Wahoo!!! Lets get this area rolling with members pictures of their favorite rocket boosted gliders!!! Either your own or one you thought was pretty cool :D .

I'll start with my current personal favorite which most of you have already seen. My 4" Mach 10. It just had 2 more flights this past weekend at the blue/grey regional. This thing has flown about 30 times now and is still going strong. I want to make a BT-80 based RC one for the new Quest D5-4 motors, but the vendor I was waiting for tiny servos from just delayed their release :mad: .

I love your upscale Mach 10's I remember you showing me them at NARAM 35. IIRC you have a the elevator neutral during boost and it flips to glide position at ejection. Do you have any plans/diagrams on how you set that up?

Here are some pics of my favorites. One photo is one of my Sky Dart launches, another is the rear engine BG I designed for THOY, and the rack photo has my Space Twins 2000, Nighthawk, Competition BG, and Sky Dart. The Sky Dart is hands down my all time favorite.

Scott, you already posted pictures of the coolest glider I've seen in person.

As for my own gliders, I really do need to repair my Fake Wulf's wing tip and try it again.

Plus I ought to try launching my Edmonds Deltie again some time. It may need a new booster, since I left the original one sitting in my car for a year or so and it got a little bit brittle from the heat and sunlight.

In this case, the most interesting part was resurrecting the wrecked birds.

And here's one I had high aspirations for that turned out to be quite a turd. But I still have hope for it. I picked up a piece of hard, trailing edge balsa stock at the RC hobby store the other day in hopes of upscaling the Zoomies a bit, and seeing if I can get them to fly. <fingers crossed>

Hi Eagle,
Nope, I went the lazy route... It will boost straight hands-off... I do like doing a few rolls and sweeping turns with it under power though. It ejects a weighted cone just like the original one which gives it its ballistic stability on the way up. I will be reducing the weight in the nose for the next few flights though. As a result it will fly higher, but I will probably need to feed in a little down elevator during boost.

I love the Sky Dart too... I have a Neubauer Rockets "Sky Dagger" that I need to get built. :rolleyes:

How well does your Space Plane glide Bob? I never got past trimming mine before it got crunched. It's repairable, but on the back burner.

How well does your Space Plane glide Bob? I never got past trimming mine before it got crunched. It's repairable, but on the back burner.Actually, it glides fairly well most of the time. It's the boost that sometimes gets exciting, especially with any kind of wind.

The spin tabs on the rudders don't really make it spin. It's more like giant barrel rolls. I could improve the boost with more nose weight but haven't gotten around to it.

I have the nose cone friction fit with some tape so I could add weight if needed but I did a lousy job of gluing in the bulkhead. On one flight, one of the "energetic" ejection charges blew the bulkhead and nose cone off the front. :o I was able to find the nose cone and it's since been repaired.

The elastic that pulls up the elevons could be better. Sometimes one of the elevons doesn't get pulled tight against the stop and the glide suffers.

My old Spaceplane boosted better and had a good glide until a shotgun ejection charge blew part of the elevon and elevon stops off. :mad:

The spin tabs on the rudders don't really make it spin. It's more like giant barrel rolls.
The R/C "2X" SpacE Plane i made, for C6 boosts, flies too fast for me to control the boost. What I did was to hold the ailerons (mixed elevons) hard over to make it roll a lot, to even things out. What I would suggest for the original model is to delete the spin tabs (GASP!), and arrange the elevons so that one is "up" by say 1/8" and one is "down" by 1/8", to make it roll. The key is to get equal up and and down angles. So, one up 3/16 and one down 3/16 also should be good, maybe better since it would roll faster. Maybe even 1/4" up and down. It will take a bit of tweaking of the mechanics to get the elevons to be that way for boost, but it is not really a big problem

BTW - bad news. At a launch last week I was doing a "routine" flight of the 2X SpacePlane. rolled fine on boost, as usual. I go to transition it for glide, and nothing, it just keeps rolling, al l the way into the ground. I suspect that the battery connector lost contact at liftoff. But the R/C gear was working after it crashed, so the lost contact was intermittent (so, it did not get unplugged). The model is repairable. The biggest issue right now is one servo arm broke, and I do not recall what servos are inside there (permanently glued), so that I can identify exactly what brand and size of output arm needs to be replaced.

Not yet. I actually want to save those for testing out in a contest sized C Rocket Glider. The contest model boost is ALWAYS scary-hot and fast, so those C3/C4's should make it a lot more reasonable. And also should boost somewhat higher too, since a relatively draggy model is more efficient on a lower thrust engine (long as it keeps pointing up). That Quest engine would have to be a "C2" for me to be able to boost the 2X by piloting rather than rolling it on boost (the 4X Space Plane is a pussycat when boosting on a G12. But if I boosted it on a G40, and the wings did not rip off as they 100% for sure would, it would be a nightmare to boost it by R/C).

I completed the Semroc Nighthawk xkit this winter, haven't flown it yet. The Skydart is recently restored from a vintage model of my brothers, and flown for the 1st time ever a few weeks ago - it had a dangerous looping flight, pulling up just a few feet above the ground - no damage, but needs some work on the elevator to get a straight boost. I probably fly the red baron the most, it is just so easy to prep, and always puts in decent flights. The scissor wing and Semroc X-21 have flown quite a few times, and both glide quite well.

What's your experience?

Thanks! I've got about twenty flights on it... so far not a scratch. It flies great, is very stall resistant and boosts hands off in calm winds. I read some of the same reviews you did. The only structural mod was to increase the size of the strakes. The thing about a glider that size is if it doesnt touch down wings level and slightly nose up it can really tear itself up. With the R/c mod I have complete control of that.

I put togeather a 34" speed 400 wing. All I did was install the motor tube where the electric motor went. I had many good flights on e6 reloads.

It ended up going up in smoke when I tried to use an old BP motor (e5) that catoed when I was out of relaods.

Note to self install a good forward plug on the motor tube next time! :)

They dont make this kit anymore but I am hoping to get a hotwire setup going soon and start cutting my own.

I took a tip from Chan Stevens EMRR review (http://www.rocketreviews.com/reviews/all/oop_shx_star_shuttle.shtml) and rolled my own paper

aft end though!

Unfortunately, last year the booster suffered a deployment failure (dang

I built what I finally named the Big Ole Rocket Glider (BORG) in 2000. That version flew on an H73. Others have used motors from D12 to G35's. It kept the RMS casing on board and use a piston to deploy the forward elevators. Half-inch foamboard for the wing, with symmetrical balsa leading edge to frame the foamboard. The rudders and canard were regular 3/8ths inch FB. That noble looking fellow is not me, but was one of the OKC Tripoli folks. The launch was the coldest one I have ever been to, with the north wind blowing from the Artic circle straight through western Oklahoma. Love to see your stuff, AstronMike.

I like the Stiletto designed by George Gassaway. It's a slide wing rocket glider. The wing is held back toward the tail under boost and then slides forward when the ejection charge burns the string holding the wing back. Another rocket glider design I like, don't know what the name is, but it's a sliding pod design. The pod is forward under boost and then slides back when the ejection charge occurs. I haven't seen the plans for it. There is a similar rocket glider called the Nymph designed by Geoff Landiss. I believe both of these plans are available through the NAR website.......

The Canaroc Space Models - Nomad:

http://www.leo.nutz.de/images/rockets/nomad_glider.jpg

I built this kit in 1982 and used it to compete at the world championships in Poland in 1983 for the German National Team. On it's first flight it glided out of sight and was lost, so I thought. Later in the day a competitor came up to our tent with the glider in his hand. I was thrilled that it was found and I never have flown it since. Too scared I guess :o

I was planning to use some BT-100 or BT-101 I have for the booster section, with a cluster of 24mm motors, and electronic staging for the X-RV, with parachute recovery for the booster section.

It's another one of those dozens of projects circulating in my mind that I just ain't got 'round to yet :(

Here are my favorite gliders:

Estes Condor Glider - right now it is painted primer white and it is waiting for its booster to be built.

Rokitflite's Fake Wolf - great design and glider. I built mine heavy so I called it "Der Flying Cow". Flew five times trying to balance it but it "disassembled itself" upon impact on the fifth flight... waiting to be repaired.

Semroc's Nighthawk - What a challenge to build. Airfoiling the wings of the glider as per instructions took me about 4 hours and an asma attack... still needs to be balanced. Right now the pod has been painted Metalflake orange and the glider is black.

PDR's Orbital Transport - this one I finished today and is waiting for clear coating.

I noticed that while sanding mine that one wing was way easier to sand than the other so it turns out that one of the wings is considerably heavier than the other

I wish I had weighed the wings before building. I would have ordered another set of laser cut parts and tried to match up a couple of wings that were closer in weight.

I added a couple of grams of lead to one wing and it's still not enough.

Between getting into gliders and no longer having the farm field I've turned to smaller park fliers. The Fake Wolf inspired me to try a cardstock/BT-5 version of a DM-1. So far I've got a 5" tube and the wings designed. This small, it might end up as tumble recovery...

This thing has flown about 30 times now and is still going strong. I want to make a BT-80 based RC one for the new Quest D5-4 motors, but the vendor I was waiting for tiny servos from just delayed their release :mad: .

I completed the Semroc Nighthawk xkit this winter, haven't flown it yet. The Skydart is recently restored from a vintage model of my brothers, and flown for the 1st time ever a few weeks ago - it had a dangerous looping flight, pulling up just a few feet above the ground - no damage, but needs some work on the elevator to get a straight boost. I probably fly the red baron the most, it is just so easy to prep, and always puts in decent flights. The scissor wing and Semroc X-21 have flown quite a few times, and both glide quite well.


I was going to ask you about the scissor wings performance. I have been thinking about getting one for awhile now, just wondering if it is worth the effort.

I love gliders, but don't fly them often. Our model rocket field is too small - my little Sparrow (http://www.payloadbay.com/article-sparrow.html) left the field flying on a 1/2A motor. And when I'm at the high-power launch site, I spend all day getting my big rockets ready to fly, so there's no time for gliders.

I'm gonna have to find more space and time. :-)

I'm a huge fans of Edmonds's gliders. Generally, they don't require any hand-tosing to set the trim. My favorite is the Deltie Thunder (http://www.payloadbay.com/article-launch-of-a-deltie-thunder.html). It's a big glider that flies great on Aerotech E motors.

I recently found out that my neighbor flies RC model planes. One he flies is a carrier for a rocket-powered glider his friend flies. They use "First-Person View" cameras to see, in real time, the "pilot's" view from the planes. The glider flies on Aerotech G motors. Some video:

http://www.payloadbay.com/video-7968.html

AstronMike builds some really cool gliders that are terrific performers. (Some even land themselves gently on your parent's RV's canopy.) Here's a video of several of his flights:

The attached are fotos of the first generation delta foamie RC Rocket Glider designed by me and The Tellurian.

He was marketing the dogtoothed leading edge version called Snaggletooth.

The model is:
an all foam delta,
Fully Symmetrical,
40" wingspan,
2 channel elevon controlled,
Powered by 24mm engines (Estes D11-P, E9-P, or even Aerotech E15-P)

We have flown it two staged with a D12-0 and D11-P and more recently E9-P staged with D12-0s.

This was originally posted on RC Groups way back in 2003.

Neither Tellurian or I have flown these foamies in awhile. Boosts had to be flown up due to the thrustline and no dihedral. Floating was awesome though.

marpe
09-30-2009, 07:53 PM
Intended as an RCRG trainer that was more robust than a balsa glider I tried some unique tricks with 4mm corplast.

Unfortunately it does not boost hands off and thus can be very dangerous in the hands of beginners.

So no plans to share on this one.

I have flown it single and CHAD staged with D12-0s and up to E9-Ps.

Look for the ejected D12-0 casing in picture 3. Pic 4 shows the delayed ignition of the sustainer due to a jetex wick delay. This buys me another hundred feet+ of boost. Way cool!

Glides like all flat plate deltas do (ie. like a brick)

Total glide time 1-2 minutes depending upon how well I can control a vertical the boost.

Very nice! I took a slightly different approach. Modified an Edmonds ECEE Thunder for R/C. It uses 2 servos for pitch and roll control. One additional servo is used to lock the canard flap down for glide ( it is allowed to "float" during boost ). Turned out to be very well mannered during boost and easy to fly during the glide. Mini-how-to posted (http://www.rcgroups.com/forums/showthread.php?t=735338&highlight=ecee+thunder) over on RCGroups.

Dusted it off after a long, dry, burn ban summer and flew it last weekend. The best photographer in the club was out there and got the shots below. Enjoy.

Well,who doesn't like gliders? This is the current fleet,and I have a few more tricks up my sleeve...I've just put the F-22 together and I'm really impressed with how well this glides,perfectly flat without any noseweight,but I haven't cut the right side aileron into it yet. The Space Shuttle is also good,oh,and the Trans Wing is a great flier too. I don't know about the scale Shuttle though,it'll probably never fly. I'm threatening to open that Sweet Vee up,it would be a pretty cool plane,maybe with a ducted fan too!

My favorite gliding model is the MPC Lunar Patrol. This is the clone I built a couple of years ago...

georgegassaway
03-17-2021, 06:55 PM
The MPC Lunar Patrol was my first successful glider model. I tried an Estes Falcon, which on flight 1 death dived into the ground. After repairs, flight #2 shredded to bits on just a B motor.

For the Lunar Patrol, I painted one glider fluorescent blue, the other fluorescent red. My first ever contest, in Atlanta in 1971, I used that for B or C Boost Glide. I wanted to say time the red one, but they said they would DQ it if both gliders came off (My first exposure to the "DQ anything unusual" mentality by some contest officials). So I taped the blue one to stay on. It did not win of course, but may have taken 3rd or 4th (maybe out of 3 or 4 fliers, unless someone DQ'ed).

I got a "wee bit" better with gliders after that.... :)

My 1974 fleet for NGRM in 1974. They sure had a lot of glider events that year. Several slide-pod R/G's for C R/G, a small swing-wing for 1/4A or 1/2A R/G, a Tandem-wiged glider AND Flex-wing for either 1/4A or 1/2A B/G. And an LM for Plastic Model, which IIRC did not fare well (I've built a much better flying LM since... :) ) .

My first successful boost glider was the Estes Orbital Transport. Loved that thing.

My Estes Falcon was built and tried earlier, but it boosted right into the sun glare and vanished on the first flight, on an A motor. Never saw it again, even though I did a good search grid on the large field.

Did an Estes Space Plane next, which I got to work fairly well. Little tricky to trim.

Did my own interpretation of the Space Twins dual boost glider from the Estes free plan. Did not change the gliders, but used a BT-20 booster instead of BT-50. That worked very well.

I have probably built just about every parasite boost glider kit since the 1970s and a number of other boost glider kits and a few rocket gliders. I designed a modernized version of the Space Twins called the Gemini, with two stylized Space Plane-like gliders (more wing sweep and swoopier tail surfaces). Flew this at the NARAM 32 sport range in Dallas in 1990.

Circa 1981 I built a modified Larry Renger Skydancer RC BG. My first RC boost glider. Used strip ailerons instead of conventional ailerons (for ease of construction and simpler linkages) and changed the shape of the twin vertical tails, just for fun. I had at least 100 flights on that thing, mostly using CHAD staged D12-0 to D12-3. Was a little boring on a single D12-3. This model was also flow at NARAM 32 in Dallas. I think there is a picture of it in the NAR magazine article that covered that NARAM. Have not flown it since around 1996. Still have it and it is still flyable, if I install a modern RX.....

Lots of things, since. Wish I had pictures of all the old ones I built.

Edit: I ran across a newspaper picture of the Skydancer going off the pad at a model airplane fly in called SMALL Steps in Little Rock, AR in June of 1990...31 years ago. And, the model was already 10 years old. Me at the rear flying and my old buddy Randy Rogers doing LCO duty. Not a great pic, but about the best I have.

Starting about 2014 I did a number of RC RGs and a couple of RC BGs. I did a number of Depron profile rocket gliders inspired by Frank Burke's designs.

Here is a nice shot of my OD Depron profile XB-70 boosting on AT E-6 power. I had a bunch of flights on this thing before bringing it to NARAM in Springfield, MO in 2016. A very nice flyer. Just before the event, I went to a lighter single cell 450 lipo for RX power, which replaced a stand alone BEC and a 2S 270 or 300 lipo. This removed a little weight and reduced the drag a little. Great, except for the fact that it now being lighter and less draggy it was able to reach and exceed the speed of foam on boost when flown at that NARAM. Ouch. All repaired shortly after, with a nose transplant and some new carbon in the fuse to make sure the speed of foam is now higher for that model. Still flies well.

One more post about gliders.

I took a bunch of models to NARAM 58 in Springfield, MO in 2016. Too many, as I did not get around to flying them all in three days.....;) However, it is always nice to have options on what to fly.

Here is what I brought: Left to right starting with the Bomarc: Dynasoar Rocketry Bomarc, My own design XF-108 Rapier, My own design glide-able SA-14 Archer, Dynasoar Rocketery profile InteRCeptor, own design semi scale Blackhorse spaceplane, RC parasite Guillows foam Space Shuttle, own design A-4B RC BG conversion of the Estes V-2 kit and my own design free flight Mig-21 BG. My slightly broken XB -70 is in the rear. Up front is my own design Douglas D-558-III RC RG and my Dynasoar Rocketry profile X-15.

Flew the Bomarc twice, the InteRCeptor once, the Blackhorse spaceplane once, the D-558-III once and the X-15 once, plus the attempt to fly the XB-70. Also flew a few conventional rockets at NARAM that year.

Partly in view on the right is my friend Richard Ng's F-104 rocket.

A good time was had!

It would probably be awesome on a G12. But probably best to do an F13 boost first to be sure it does not go out of sight.

Thought about it, but it is on the edge of OK on the chad staged D12s. If you do not hold at least an 70-80 degree climb, it builds up a little airspeed and gives off a little bit of very high pitched aileron flutter, almost like a strummed electric guitar note....:) Easily fixed with a aileron counterweight, I predict.

I am a little tempted to fly it this summer, in its 40th year of existence. Might just convert it to a fixed pod and fly it on a E6 reload.

Still have a Phoenix to build for the 32mm case. Might happen, now that I am retired!

Oh, had not thought about aleron flutter an an F13 or G12 boost.

Thing is, not so sure an E6 would be enough thrust for it. Well, maybe a 45 degree tower launch, with an "accidental" blip of down to climb at first at about 30-ish degrees to be sure of eough airspeed before pulling up more steeply.

What does it weigh? Of course, all this time later, maybe you could put in even lighter new radio gear and lighter batteries, and go with fixed-pod so the lighter radio gear up front could be counteracted by the E6 reload and pod mass.

It's so weird to realize that 2-channel R/C R/G's I built in the 1980's for Cannon R/C gear, total R/C mass of about 2-2.25 ounces (with 50 mAh Nicads), can be done NOW for little more than the mass of the receiver alone (about 6/10 ounce).

I've made 2 to 3 Estes kits before that (1970's), then a "twin Skydart" model in the mid 2000's (rudder-only RC for each). Kind of like the "Space Twins", or Lunar Patrol with two gliders on each side of a core rocket.

Sometime...I want to do a 1.4X or so RC Skydart. Likely BT-55 size, but maybe 1.5X sized flying surfaces. The 2X needed a D12, but was best on E's. At about 1.4X or so, it could work pretty well on a C6, I think. More economical to fly. Ironically of all the R/C gliders, I don't have something I can just go ahead and sport fly off a normal launch pad or rod. Last time I sort of did, was an Astron Space Plane RC 2X, built mostly as a test model for the later 4X. The 2X flew on B's and C's. Had an accident though, so long gone.

The concept was not new, but the flop-wing method for a flying wing sort of was. Had terrible yaw stability problems (as in no yaw stability) til I added half-round rudder tips, problem solved. Had a bit of a flaky glide trim though, a bit of dutch roll and glide smoothly one moment and bobble a bit too easily from a minor air current.

The wing fold method worked very well, but this was not the deep dive part.

THIS was, using the wing fold tech for a "conventional" glider, 36" span:

To fit into a 2" tube, the fuselage had to fold in 3 places, plus the horizontal stab rotate 90 degrees, plus the offset rudder to fold flat. It was a "Eureka" moment when I stopped thinking of folding the fuselage vertically (pitch axis), with all sorts of complications, to horizontally, which solved so many things.

There are reasons why I kept the project under wraps at the time, and then did not end up using them after 2012 (main thing is the FAI rules changed S4 into "Rocket Glide" after 2012, and a bit risky for NAR contest flying).

The folding FAI glider is fantastic.

I still have an upscaled Skydart and Spaceplane on my long term RC RG build list.

I have a vintage Skydart kit stashed back, a build and flown but unpainted version of the modern Skydart II re-release and a new in bag modern re-release.

A local hobby shop, Roy’s Hobby in Hurst, Tx still had three or four of the modern version of the Skydart kits hanging on the wall when I was there last week, at the old retail price.

George,

Did you ever pursue that folding conventional glider design further or abandon it, due to the FAI rule change ?

George,

I saw and read the thread at that link.

I guess my question should have been " did you ever expand the design into using vacuum-bagged foam wings and control surfaces, for even more weight reduction" ?

Frankly, your folding glider designs are fascinating, George !

Have you ever considered an RC version ?

With the previous mention of the R/C Astron SpacePlanes, here is a link to my website, with some info and pics about the 2X and 4X versions.

If you look close, you can see the joint where the BT-80 separated for transport along with a bit of the forward part of the wing. Shipped in a cardboard box.

And I recently found this video of the 4X flying at NARAM in 2008, so posted it on Youtube:

George,

With all of the knowledge and experience you have, you should write a book . . . Seriously !

It would be a great resource for Rocketeers and a "legacy" for future generations to use and enjoy !

So, no new gliders, in 12 years ?

C'mon, guys !

Go to the 2nd post here < https://forums.rocketshoppe.com/showthread.php?t=12652&highlight=flying+jake > for 'Bumble Bee' launch and glide pics. Not sure what the current record is for 1/2A boost Glide Duration, but this one was still rising on a thermal and disappeared after at least 15 minutes.



I've since built 3 of the Bumble Bees, but haven't flown them yet.
The CMR Stingray is finished, but has yet to be flown. The CMR Buzzard still needs a few finishing touches, and the Geoff Landis Goose III is still in a shoe box.

The GOOSE III image won't enlarge.

In addition to the GOOSE III, Geoff Landis also designed the GOSLING.


Did you make any patterns of it ?

I just added a new photo of the Goose III parts. I did make patterns for both the Goose III and Gosling, but cant seem to find them right now. On a side note, the Gosling plans do not include a pattern for the rudder. I was just going to - wait for it - 'wing it' when I get around to building one by enlarging the drawing in the plans.


I did build a Goose III years ago (1998?) and flew it at a CMASS launch. At about 50' up, the back of the canard broke off - I may have put too much camber in it - but at pod separation it transitioned into a beautiful flat glide. The wind carried it into some tall grass and I never recovered it, but it really is a nice glider.

I suspect that "flutter" might have been a possible cause for the Canard failure . . . Thoughts ?

Absolutely, tho 'fwapping' might be a better description. My CMR Manta made the same sound before it 'exceeded the speed of balsa' on a B6-2.

I think that particular Canard is prone to flutter / "fwapping", due to its high aspect ratio design.

Using "Balsa Plywood" should cure that problem, since it would be stiffer and resist flexing during boost.
