Well I thought I'd chime in again. Just for kicks, I pulled the LA65 off my Ultra Stick 60 and put in the Tower 75 that I had sitting new in it's box. Man, what a combo! I ran two tanks on the ground to break the engine in and sent her up with an APC 13.x6. The US60 flies awesome with the TH75. I can actually hover at 1/2 throttle and I'm not even that good at hovering.
