Just an FYI,
Estes is about to release scale models of a whole bunch of X-Prize contenders, and one of them is the Canadian Arrow. This is basically a stretched V-2, and the scale model is to be a 2.6" diameter version the same size basically as the old Estes BT-80 based V-2. All you'd need to do is shorten the body tube a bit to make a V-2.
This ought to be awesome on E and F Aerotech 24mm motors, even more so if you want to modify it for a 29mm MMT. And just $17! (mail order price.)
Let's see, I need one to build stock, one to build as a V-2, another to kitbash into an A-4B, another into an A-9....
