Does anyone have a pic design for a r/c speed control pwm (unipolar) or know where I can find one (I know nowt about R/C) but need a motor speed controler for a motor which draws about 200A @ 24V locked rotor current I can sort the power chain easy but am looking for the interface to raido control (pain to do with servo and pot) The output only needs to be single direction as a contactor will be used for reversing. Hoping to enter into ROBOT WARS (silly UK tv program) TIA Steve......... :-)
