Replace brushed 480 with E-flite 480 outrunner, Hi-tech micro receiver, Dualsky 40 amp ESC, eflite micro servos.
You will need to create an engine mount. Couple with 22ma lipo and this bird has plenty of torque with scale speed.
Looks the part in the air and due to hand-launch, belly land, no under carriage looks even better.
