The ARF is supposed to be available the end of this month on Tower's site. I am planning on holding out til mid-july for the RXR version which comes with a Rimfire Motor, Silver Series ESC, and servos installed. I imagine the 42-40-1000 motor should have plenty of power for basic acrobatics. The ESC will take a 4S lipo. Typically I would just get the ARF and install my own electronics, but for the money ($239.99 on tower) the RXR will give me another fun sport plane to put in the air quickly while I spend my time building other projects.
