Soyuz lift off on 17 motor
cluster flight
2 video
Rocketry Forum thread
Modified build of the Vostok
kit by
Cosmodrome Rocketry. 60.5 inches tall, 1/33 scale.
Flight weight 10lbs, including 2lbs of motors and 1.5lb nose weight.
1x ProX F30 (24mm 3grain 73Ns) + 8x Estes E9 + 8x Estes D12
433Ns total impulse = I impulse
198N average thrust, average burn duration 2.2 sec, with the E9 burns ending
at 2.8 sec
At about 1pm on a beautiful spring day, the Soyuz lifted
off on a column of fire and smoke for a very nice flight.
All 17 engines fired and both Top Flight Recovery 45 inch chutes deployed
cleanly. This second flight was nice and straight, without the coning seen
on the first flight. The boosters remained firmly attached to the core as
intended, and all major sections of the rocket are in great shape.
The excellent Rocketflite CF igniters are mostly wired in
series strings of 2 and then those are joined in parallel, reducing total
current load.

Lifted off on 1x H54 + 1x G54 (both Pro-X 29mm 3 grain loads) + 8x D12.
Experimented with higher total lift impulse for this flight, got slightly
more altitude but saucer landed at an angle. Saucer is still in great shape.
The Turbine Rocket Saucer
went up for its 37th flight (no pictures) and ...
