I think I saw it in the Model Rocketeer mag, though I can't recall what issue date.

Tried this trap door type of pod and didn't like it because the door wouldn't always open or the streamer wouldn't come out but worse of all the tape wouldn't hold the pull string so it just spit the motor and the pod would stay stuck on my glider. I am making a couple of rear eject pods like from this thread because I can see its a better idea and WILL pull the motor and pod off backwards out of tbe way. So no more tangled gliders. |

That's the pod from a "GEODETIKA" . . . I always wanted to build one of those, but never did. Personally, I think it needs more Rudder area. Dave F. |

Just wanted to reiterate the importance of keeping the CG location of the rear-eject pod the same as the original kit pod, whether retrofitting or fabricating a new rear-eject pod. The original pod’s length and balance point (with an unfired motor installed) was chosen by its designer to ensure a stable vertical launch and minimize or eliminate looping or weathercocking on ascent.
This becomes even more important with gliders with pre-canted forward canard wings. If designing from scratch, the launch CG of glider and pod with an unfired motor installed should fall at or near the center of lift of the canard.

removed the unneeded commentary....
https://www.nar.org/contest-flying/...0 the%20glider. I would just attach a kevlar cord between the 2 parts... http://georgesrockets.com/GRP/RandD/Spooler.htm http://georgesrockets.com/GRP/RandD...ler_Pod_R-D.pdf it appears your pics show a reverse spooler pod ejection system.....

Not actually. Only one item to recover, less complexity, my system ejects recovery gear backward and out of the path of the glider.
