Can you use a short motor in a long motor mount tube?
In particular, the question is what if you have a short Aerotech 38mm 38/120 reloadable in a MMT maybe 10-12 inches long - is that ok as long as the parachute and stuff fits in the rocket ok?
Any chance of the ejection charge busting open the MMT from the inside in a case like that? The charge would be down in the tube a ways in a case like that.
I know its ok for the motor stick out and to be longer than the MMT, but wasn't sure about if its shorter.
Maybe Im thinking about it too much but thought Id ask.
