Tweener,

You really don't need the "E" motor to get this rocket to fly well. On a D12, the simulator gives me 488', and it reaches flight velocity at 41", meaning you need a 48" rod.

The "E" motor gave me 934', but it needed an 8' rod to do it. That suggests more of a structural tower to keep it straight. Too much support tower for a one-bird project.
