reprogramming the circuitboard sounds very questionable to me. i don't think that reprogramming the circuitboard can be done with box-mart junk, and you'll still have to create a whole new circuit for the radio signal decoding and frecuency crystals along with use up-to-spec mosfets and the like. it's not as simple as just a simple program. proportional steering and throttle is a complex program and unless your dad makes a living, programming proportional rc vehicles, it's going to be next to impossible
