I am new to r/c planes and I just wanted some advice. I am going to buy the Hangar 9 Twist 3D. I wanted to know if it came with a engine and if it didn't could somebody tell me a good engine I could put on it. I am also going to get a JR XF421EX Aircraft Radio System. Will this work with the Twist? And is this ll I would need to go out to the field and fly or is there something else? Thanks.
