Throttle in Manual mode (not working) and stabilize (working)

Posted by Victor on May 4, 2011 at 12:59pm
Hello,

 

I have an APM 1.0 board that gets power from an ESC, LIPO battery 11.1. I have connected 3 servos, xBee, Mediatek GPS and the RX to the board. When I'm in manual mode I don't have any control over the throttle. When I mode the stick to 25%, 50% and 100% nothing happens, but when I switch to stabilize mode, the motor rotates the way is supposed to. I've been reading several of the forums but the discussions talk about manual working but not stabilize. Any suggestions as to what could cause this anomaly?

 

Thank you

    Possibly your multiplexer chip is damaged and the manual input side of the throttle channel is burned out.  If you are in "hardware manual" (eg pwm value on ch8 above 1850) then there should be a direct hardware connection from the channel 1-4 inputs to the channel 1-4 outputs.  Only a hardware issue can interrupt that.
