Raideron, Thanks for the info about KE coupling. I'll have to set up my radio some more. Also thanks for asking about flat spins. I was just trying some tonight (inverted) and couldn't get the nose up. It seemed to be spinning faster than I wanted it too as well. On the product review videos it seems to be spinning slower. Gotta work on that. I also have a Saito 82 with an APC 14x4 W prop. Thanks again. Rob
