Her is a shot of one that no longer exists from a bad battery about 3 years ago. It is the WM 40 that I recovered with a G90 and a 12/8 apc prop. I felt that was the best prop for speed on it. Make sure you beef up the firewall inside and out. Beef up the retract mounts on the inside by slooping epoxy in their to the corners. I installed a larger tank. Get the cg right on and also do a lateral balance. I flew that thing for a couple years. it was dead on. i have a couple with Saito 100 and 61fx.

I'm curious as to what kind and size prop are you using on the tower 75
