Yes, there are 5 Input channels that control 4 axis. THR, RUD, ELE, AIL, and PIT. All these signals are mixed in the uC with the Gyros output, and the axis is kept level. Transmitter is normal 6 channel RC radio. The uC controls the 4 motors in unison as well as semi independently, to allow this to ...

Greetings Vic, The ESC Accepts the same kind of signal as the Direct Output from the Rx, which is a single pulse of PWM So the next step is to measure the timing of the PWM signal from the control board, and note the repitition time (ms), signal for min and signal for max (us). Also confirm the sig...

Greetings Vic, The bottom of the Diag should say Brushed Motor in stead of ESC's Got it! So the controller is already sending four channels of PWM signals to the existing motors? CORRECT I jumped to the conclusion that you had R/C servos, but more likely you have DCPM (brush motors) running from PW...

Servo Problem NEED HELP
I am trying to convert a Walkera X-UFO that has 4 Brushed motors to be able to use Brushless motors. The Signal coming out of the Rx is PWM, and the signal going to the gate of the FET's is a Pulsed signal. Here is the Time's I got. Hori Div = 2v div. Vert Div THR IN 1v div Vert Div THR Mix Out .1v ...
