For anyone who may be unfamiliar with it, here are a plan and a review of the "Flyin' Stovepipe" boost-glider (see: http://www.spacemodeling.org/JimZ/eirp_56.htm and http://www.rocketreviews.com/estes-...epipe-plan.html ), and here is an article (with plan, see: http://jetex.org/models/plans/plans...da-am-5611.html ) on what might be called the Flyin' Stovepipe's "Jetex coleopter ancestor." Also:
Regarding aeppel cpm's problem with the booster failing to disengage from the tubular glider of his Flyin' Stovepipe, a more loose coupling between the booster's fin tips and the inner wall of the glider (perhaps using dowel "hooks" that engage launch lug "loops," similar to the way the "parasite" gliders in the Estes Condor, Firefly, and Orbital Transport kits are affixed to their boosters) would facilitate separation of the booster from the cylindrical glider at ejection.

Centauri
I built this 2/3 scale Coaster Centauri a while back and thought that it would be my least performing glider. Boy was I wrong, at a club launch I put it up on a C6, at ejection it caught the wind and went around 300' downrange, it would still be going if the wind had not settled.

One coloring trick...
It was either here or on TRF that I read about a method of coloring a boost glider. I have yet to try it myself on a glider, but I can say that it works for balsa nosecones.
Take a packet of RIT Dye (the tie dye stuff), and dissolve it in 91% rubbing alcohol. Then you brush this over the area you want colored, and allow the alcohol to evaporate off. The dye and the salt remains, but the lack of water doesn't affect the balsa much. Once you knock off the salt, the results are fairly even. HTH Jim .

Interesting... Even if perspiration (say, from handling such a model out on the flying field on a hot day) causes the dye to "wick off" (which it may not--I don't know), more dye could always be applied as you described. Another thought: This coloring method might be good for use in some group model rocket-building sessions, especially with younger kids, because it should dry faster than paint.

There's an article on Apogee's site about using RIT on balsa.
I have an idea for an alternative Stovepipe booster, but I want to build and fly it before I talk about it. I like the post and lug option. What kind of wire makes the landing skid on that Centuri? I've been looking for something like that as I further upscale the Hummingbird. |

Made that skid with music wire, don't remember the size (.035 maybe). Hobby shop should have it. |

A second parallel rod is useful as an umbilical to tape the clip leads out of the way of the glider's wings and tail. Bill
