    I bought a 24 mm Rocketarium retaining system from Apogee and attached to the aft end of the stuffer tube with JB Weld. This should insure that the stuffer tube is ejected on the next flight without ejecting the 24 mm motor. I took a file and just light removed a few high points on the lead wrapping on the forward end of the stuffer tube. The stuffer tube should be ejected on the next flight.

    I had bad luck with the German A4b at Hellfire-22 flying on an E12-4. The E12-4 worked fine (lot# A 06 22 12) and the Apogee motor retainer worked, also. I used the Orange transmitter, which had only a small amount of flap change using the trim control. The flap lever on my Orange transmitter does not work. I knew this before the flight. I am thinking now that I should have used the joystick to bring the nose up, but I didn't do anything. The A4b stuck in the salt with damage. I am thinking of making taking out the R/C and setting the flaps to the right amount after the pop pod has ejected. The pop pod was also damaged on impact.

    I've always though it interesting how much the A4b looks like the F-25 Firelily.
    (I didn't try to RC mine, though!)

    Well it sounds like its repairable but unfortunate none the less. That Orange is a Lemon [no offense to Lemon owners] That is one huge area for recovery with no trees, good for boost gliders though. A bad hip means flying it back to myself is the only way for me.

    After crashing my R/C German A4b (see Post#92) patterned after Tom's design that started this thread, I decided to take out the R/C components and convert the model to a more conventional boost glider. It took some re-constructive surgery just to get the model to the condition shown in the photo's. Anyways, I tied one end of some LPR shock cord elastic to the end of the push/pull rods and the other end to an internal post to install an up-elevator position. Then I cut up pieces of motor mount tubes to make grooves on the pop-pod tube to hold the elevators in a neutral position during boost.

    These look awesome guys! I can't help but look at these though and wonder if anyone is planning on or has done an up-scaled RC A4b using any of the larger LOC Precision V2 kits...

    I tend to think that the LOC V-2 kit would be too heavy. One thing that I have picked up from Frank at DynaSoar Rocketry is that rocket gliders and boost gliders need to be as light as possible.

    You could do a non gliding version using a loc kit, too heavy to glide. I have done a gliding rc version in profile of 6" diameter that weighed 12 oz, there has been one ultra lightweight depron 6" full fuse version that flew as an aircraft but could do vertol, the construction was artwork, used a pusher or fan I think.

    Mine also flew as a rocket glider by popping the electric motor off.

    My A4b cockpit was damaged in last summer's crash. I got a new cockpit from The Sandman.
