I have one with an AXi motor instead of the Rimfire. It's a beautiful flying plane. I also use 4 cell A123 battery packs. I think the Electrostik RXR is a great bargain. You get the plane,motor,servos, and ESC. It's a large aircraft, almost.40 size and best of all, it's a Stik. They've been kitted in all sizes and they fly great.
