The Hummer is designed as a 2-channel sport model and also makes a good l/2A racer. Although the Hummer is not recommended for the beginner, anyone with some R/C experience should have no problem flying it. The Hummer requires only aileron and elevator control so any radio with 2 or more channels may be used. Special micro-size radios are not required. The prototypes used 2 functions of 4 and 6 channel radios. The radio compartment is large enough for standard size battery packs and servos.
