We are using AT89C2051 for generating PWM for each motor and alreadycontrolled speed of each motor by varying duty cycle using a pushbutton.Still we are unable to control four motors using RC. Weprogrammed for sensing PWM out of RC but value is random in eachthrottle position.No problem for PWM out from AT89C2051. It sensedaccurately and constant value obtained for each steps.We are usingP89C51RD2 for sensing PWM out.Can you help me to solve this problem?I need programming techniqu..

to control 4 motors usinf and rc radio you can just connect 4 motor controllers to 4 rc channels and setup some mixers in your radio.
But if you want to fly a quadrocopter, that won't be stable enough, you'll need a control-unit equipped with gyros and ACC's.
