How much? Well..............If you mean did I need to do anything additional out of the norm I would say nothing. Its a very well built airplane and the hardware kit (like 75 bucks I think) is very complete. I went with Hitec Digitals and used a g62. I think their next shipment is in June, but you can E mail Tom or call Wild Hare to find out. Check out the Wild Hare Support forum under Giant Planes.
