More APM 2.5 Setup issue

Posted by Ray on March 2, 2013 at 4:19pm

Hi All!

 Im Ray, live in NM. THis is my first setup using APM. Im not new to helis, been flying for about 6 years, just new to trying the UAV thing.

 Im setting up a APM 2.5 on a 600E. I get to "Configure Servos' Part of the heli setup and the servos are not moving. Im using a SPectrum DX 8 and AR 9300 reciever. My servos are plugged into the outputs and the signal wire is to the inside of the board. Im getting NO movement at all. Even if they are in the wrong order I should still get movement. I have been through the radio calibration part and i have even hooked the servos to my reciever directly to make sure that everything is working correctly.

I hoooked everything up using the pic below.

 THanks in advance for the help.

    Thanks Randy:
     So then how do I recover the logs, where are they stored so that I can view them?

    Hey Ray I have an idea.

    I also get the occasional "glitch" in my collective similar to how you describe yours, only not as frequently. What radio are you using? I use a TGY-9X and the pots in the sticks are known to fail. This will lead to the problem you are describing, as the electrical contact inside the pots will "crackle" leading to glitches. I noticed this issue when I was calibrating my collective and I noticed that it was impossible for me to get exactly 10 degrees because it would jump between 9.5 and 10.5 degrees (a bad spot on the pot). IMO in my case this is definitely related to the radio. 

    This can be fixed by either replacing the pots in your radio, or getting another radio (9x is only $50 lol)

    Hey Ray, I have the exact same issue as you. If I find the solution I'll let you know, otherwise I'll look in here to see what you did to fix it :)

    EDIT: ah, just read the article.. Thanks for that :)

    How are you powering the board? If you're using the Power Module, you must have a BEC/ESC on the output side to power the servos. the JP1 jumper should be off in that case.
