No Throttle Control

Posted by Taylor Mantick on July 14, 2016 at 8:55pm

Hello Everyone,

this is my first time working with and attempting to run arducopter on an apm 2.8 board. I have everything set up and ready to go, and can arm my motors, but once they start spinning at their idle rpm's (min throttle) any throttle input past that sends my motors off at 1 speed no matter what percentage my throttle is at except minimum (when they shut off back to their idle speed). i have no control over the throttle on my copter, and my ESC's, radio, and everything are calibrated. If anyone has any idea what could be going wrong or knows how to fix this i am dead in the water and ready to quit on this board, so your help is much much appreciated.

Thanks

    Thank you so much! I don't know how you figured that process out, I had to repeat it more than a couple times but I was able to finally fly, I just ran it in stabilize for about 20 seconds a couple of times, everything banked correctly, pitched correctly, and yawed correctly, but most of all the throttle worked correctly! its too late to fully test it right now but you can bet I'll be up bright and early tomorrow to hit the local RC airfield, then after I get a little more of a feel for it and maybe some PID tweaking I'll embark on the challenge of setting up my OSD and FPV system, hopefully all will be functional by Monday when I go back to work, I am completely addicted to this hobby and the challenges it gives me, I CAN'T THANK YOU ENOUGH my friend you are aces in my book!

    Yes sir I did! I uploaded ardurover a couple of times, reset the board with that firmware a couple times, then re-uploaded arducopter back onto it, went through the calibration wizard, and was good to go. Swapping out those firmwares erases the EEPROM on your board which pretty much erases its "personality", so things that were acting funny or not quite right could potentially be corrected (if not a hardware issue) and luckily my throttle issue was one of them. Hopefully this is the case with yours as well! You can just google how to erase EEPROM on apm and you'll find what you need as far as how-to's. If you've already tried this or it doesn't help, and you've made sure you've calibrated all your hardware, check your min/max throttle (specific to copter), and throttle rate (which should be set at or near 1000 which allows you to access the full range of your throttle) parameters and verify they're in order. If everything else fails and your dead in the water like I was for almost a month, just spring for a new board because it most likely is a hardware issue at that point.

    Hope this helps
