I built the below-diagramed rocket here in Europe from stock Klima components but am a bit afraid to fly it, I'm concerned whether the chute will properly eject. The rocket is powered by a cluster of 4 Klima D9-5 18mm motors. The 0.5m bottom body tube has a Klima baffle on top. When I ordered the baffle, I assumed it would be inserted into the airframe and glued near the bottom, just above the motors, but the instructions said to mount half of it inside the top of the airframe, so it acts as a coupler. The shock cord (shown in green) runs from a wooden eyehole on top of the baffle to an eyebolt on the coupler at the top of another 0.5m airframe, which contains the chute. At ejection, the second airframe is supposed to pop off the baffle and the chute is supposed to come out. So the ejection charge has to be strong enough to pop the second airframe with sufficient force to pull out the chute. I suppose that with 4 motors the force will be adequate, but I've never seen a design like this, and the chute is further from the motor than it is in the usual rocket.
Any thoughts?
Thanks,
