I agree about the servos, go with the 645MG. I have used them in 27%-30% planes with no problems, they will work fine if you're not into heavy 3D flying,as far a the batteries goes I would not use the ones that came with the radio. A good inexpensive way to go for your first big bird is the Nickel Metal Hydride, check with Dave Thatcher at Radical RC for switches and your batteries. Just my 2 cents, I would maybe shop on the Swap shop here for an engine, you can pick one up at a good price that will be very dependable. Hope this helps
