Thanks for the info guys. I think I'll get a prop nut. I'd like to get an aluminum spinner but after looking at the prices, Yikes! I have taken and butchered some plastic spinners to fit the wide props but I don't like doing that. I think I'll order up some stuff from Tower including the prop nut and a servo reverser. Do most people use a servo reverser for the elevators or try to program it in their radio? I have a Futaba 9C but the only thing I could determine is that I would need an 8 channel receiver.
