H-quad with APM2.5, FPV, FrSky

Posted by Pedro H on June 24, 2014 at 4:04pm

Hi folks,

Building my second quad.  FrSky and FPV gears works perfectly but having trouble with APM2.5(my first time setup).  

My currently problem:

Having trouble getting the ESC calibrated.  What am i doing wrong here?
Also got this HK 15a UBEC; but not sure where wiring plugs into?   UBEC.JPG
Does lipo plugs into UBEC red wire and the 2 y-wires plugs into the APM2.5 output pins?

    Finally got H-quad built with APM2.5.2
    I was able to Save Trim today:

    But problem I discovered is interference.
    Using Mission Planner "compassmot" the result:

    -at 10% throttle: 57% of mag field
    -at 50% throttle : 151% of mag field
    -at 80% throttle: 229% of mag field


    Any ideas on how to reduce the interfaces or shield the APM2.5?
