 Top Secret 2.0

An upscaled re-design of Bret Simpkins "Top Secret" model rocket, circa 1973.

This upscale features a Pine Nose Cone, BT/C-55 Body, 1/8" Basswood Fins and Oval Tube Fins. Powered by 24mm or 29mm motors.

This rocket will be a test mule for a "new to me" rear eject that spits the motor out the back, and drags the parachute out with it. It has a motor tube to redirect all the ejection debris out with the rocket... the chute will never see the ejection charge.​
The motor slips fits into the motor tube and is temporarily secured with a small piece of masking tape.​
A D12 lifts the rocket to about 700' apogee... we'll try it on this motor for it's maiden voyage.​
 




 Here's the original "Top Secret" design and data:
