Modified Peg Perego RZR 900 converted to 24v with HPI GT550 motors

Repacked the gearboxes with grease and installed some HPI GT550 RC motors. Also modified the shifter so both motors get power from forward high.. this setup only failed because I allowed one motor to be fed 24v with the shifter in low and my kid apparently likes going slow sometimes so now we don't have that option.
