The lesser weight of the engine just pushes the center-of-gravity forward, and should result in a more stable rocket. The adapter weight is relatively insignificant in comparison to the weight loss in motor difference. The only worry on 24's is the liftoff speed. The kit has a lot of nose weight that needs lifted, and so I'd be sure to use at least a 5ft launch guide / high-thrust motors.@Apogee Components , don't mean to take too much of your time here, I want you to keep kitting more of these babies up! But have a quick question about using 24mm engines from your recommended list of those - your instructions are very clear that we shouldn't use a regular motor mount because of how exacting the stability issues are on this rocket—Tape only. But we'd have to use an adapter for a 24mm engine. Does the lesser weight of the smaller engine combined with the adapter weight still keep it within specs, stability-wise, or will there need to be adjustments made?
I ask because the 739 feet using an E-30T-4 is plenty high to make me happy, plus the lesser cost of those engines too.
This I will verify with the man at the top and confirm here today.
