Unhappy Ace Rocket Manufacturing

Ok old timers',

And that is said proudly. No disrespect.

Ok, I won a rocket called Legal Allegro from that awful place Ebay. Has anyone heard of the company called Ace Rocket Manufacturing from Mission Hills California. I actually only wanted the NC out of the kit. I won the kit without any instructions accompanying it. There was a Aerotech specification sheet that was included that is copyrighted in January 1983 from California Rocketry, if that tells ya how old the kit is. And it looks like Ace used to be located in San Fernando, CA. No street address included.

Yep. Ace made the nice lightweight 5:1 (or was it 5.5:1?) ratio nosecones for 4" tubing. At the time, PML and LOC were making shorter nosecones that just didn't look right for most of the rockets I was building, plus the ACE cones were cheaper. I have several of them on my HPR rockets, but I don't have any unused ones left.

Korey Kline founded the company in the latter 70's, IIRC. He later formed Hypertek which makes hybrids.

If any of you read Rosinfield's Launch article, he conviently left out the fact that a Hypertek system was the first commercial hobby hybrid flown, not as a beta or a demo, but by a paying customer. Both Aerotech and Hypertek were at the Manchester field that day flying demos. I can't remember who bought the motor and flew it, but I think I still have a video tape of it somewhere. I can't remember which launch it was, but I think it was "Spears 2" when Lamothe fried another rocket with a "dragon's breath" motor.

Ace Rockets also made the Legal Eagle rocket. It shared the "Legal" name with the Legal Allegro because both of these 3x24mm cluster sport rockets could legally be flown within NAR limits.

I think the Ace Legal Allegro used 2.25" dia. tubing with approx. 6" ogive nose cone. Maybe someone else on the forum may know but the Semroc BTH-70 is probably a pretty close match but I think Carl only makes the Secant Ogive for the ARCAS kits in that size tubing. You may consider Carl, Sandman or BMS if you don't mind a balsa cone for your kit. Back in the day Composite Dynamics and Stargate Rocketry also sold similar sized tubing but I'm not exactly sure the wall thickness, but they were heavy walled and about 2.25" od.

Al Swackhammer will most likely chime in. He has some original ACE rockets and plans. Ace parts were pretty commonplace with early HPR scratch builders and I saw a bunch of the Ace rockets in action at the first LDRS that I attended in Hartsel, CO.

California Rocketry (Jerry Irvine's publication) featured advertisements for Ace Rockets and made mention of Korey Kline in almost every issue.

Question Legal Allegro

Yah, the kit I won looks to be complete with exception of the instructions/plans (not included). I could probably build it, if I knew which side of the cut fins was the leading edge and also what distance do I inset the 3 long motor tubes into the main body tube. The kit included a NC, already cut fins (although they are warped), a baffle kit, main body, 3 long motor tubes (look to be 24mm) and a 3' estes plastic type of parachute.

It should be easy to determine the root edge (edge glued to the tube) of the fins as the grain should always be semi-perpendicular to the body tube (it should NEVER be parallel to the tube).
The grain should slope from highest point (in relation to the nose of the rocket) on the root edge to lowest point on the outer most edge from the root.

Red face Legal Allegro

Ok. I knew that. I must have had a blonde moment. Now I feel really dumb.

I have done web searches for pics or plans, and can not find any. After I get home from work today, I will try contacting the original owner of ACE.

Are these plywood, basswood or balsa fins? The grain should tell you for basswood or balsa, but grain is often ignored with plywood because each ply runs a different direction anyway.

Basswood. but really warped. Less hassle to just cut new ones.

I can see where finding the root edge of this particular planform could be a problem since you lack the instructions because of the fin design. These fins mount in the same configuration as the LOC/Precision 4-29SS, not like the Public Missiles Phobos.

Legal Allegro fins mounted the same as the Allegro fins, see below. Allegro had four motor tubes with four fins and the Legal Allegro was basically it's baby brother.

Personally, I'd cut the new set from 1/8" Lite Ply.

Your three motor tubes should be about 23" long and should extend out the main airframe about 21". Do you have a tube coupler with your kit? If so, the motor mount tubes mount in that tube coupler to center it into the 2.25" dia airframe. How is the fit of the motor mount tube in the main airframe?

Hope this helps.

Cool Legal Allegro

Steve,

Thanks for the information!!! It really helps. I will develop the rocksim file tomorrow during my lunch break. Yah, I took the measurements of the kit parts when I got home today. Yes, the MTs are 23" long with the BT being 17.5 inches long and 2.25 inches diameter. Nose cone measured about 5-5/8 inches (above the shoulder) with 2" that will be sunk in the BT when mounted.

The fins are a in the shape of a elongated right triangle with sides of 3-5/8 x 9-7/8 and 10.5 inches per side.

The header card mentioned recommended motors of 3 D12s or 3 E6s.
I will have to run some rocksim comparisons to see what would be optimum. Lord knows I wont be able to launch until late april. Oklahoma has some bad winter time weather. High winds or its always drizzling and raining.

Although I am starting to dabble in some KN/DX motor technology lately. I have been surfing Yawn's and Nakka's websites. And have actually made a new 18mm motors that ran just fine by themselves. A little more practice and I might make the jump to 24mm ones.

Again thanks for the information.

Just Jerry from the Rocketry Planet forum said to keep the paint job simple with black fins and NC and florecent orange for the BT.


Tony




I will make a post trail when I start building it.
