At Mid January i started to build the Sputnik, I'm using the Leo's model HERE 1:48 Scale and converted to use 2 Stage and clustered.
Is designed to use 1 D12-7 on the stage 2 and 4 A10-0T on each boosters. the A10 should be without delay to release the bosters as soon the motor turn off. each booster will have 2 engagement devices 1 in the nosecone another in the bottom of the booster, the nose cone engagement device will release when the ejection charge push the nosecone then the shock cord will pull the botton engagement device and the booster fall using a a stream, the stage 2 continue flying with the D-12 Motor and will use a parachute.
all to easy
As soon i start i realized that was many factors that i wasn't considered so i made some modification, but i'm still afraid that the ejection charge will be not too strong to release the bottom engagement device cause the stage 1 will continue thrusting so will be not time to release it. but we'll see
this is the initial squema
