if a rocket advertises that it goes 1000ft. i assume that it is the max height of the c engines. is it a general assumption of B engine 2/3 that (670) and A engines (about 350), or is this way off. just curious in guessing how high some rockets will go with differant size engines.
thanks

You're probably close in looking at it this way. However, I have noticed that if a rocket will do about 1,000' on a "C" motor, it will be closer to around
500' on an "A." Joe A. South Louisiana Rocketry #8

Andrew,
The letter A/B/C on the motor refers to an impulse class that doubles with each letter. B is twice A. C is twice B, and therefore 4 times A. D is twice C, or 8 times A, 4 times B.
Given that, a better estimate would be that a B would fly half as high as a C, and an A would fly 1/4 as high.
If you are really curious, you may want to check out RockSim software from Apogee Components. You can download a free demo copy at
Hope that helps.
