ArduPlane fails to connect to MP with 3DR Radios

Hey all,

I've been using the 3DR radios successfully on my ArduCopter for about 2 months now. I recently ported the radio and my APM to a newly built Skywalker 168cm with the hopes of an AP/FPV enabled fixed-wing aircraft. 

After I uploaded the most recent ArduPlane software (2.5), I am having trouble reading telemetry from the APM on the MP. I don't think the radios are a problem since they've worked in the past and they both display a solid green LED when I power the aircraft radio WITHOUT connecting TX/RX to APM. However, under normal circumstances, when I power the APM and thus the connected aircraft radio, it immediately displays both a blinking red and green LED and fails to connect to MP (timeout error). 

(I do not have the USB connected at the same time)

Has anyone run into this error before? Perhaps I am overlooking something simple.

Thanks,

Franco

    Then test the radios first before asking for help.  If they work then don't title your thread to imply that people are having problems with the radios, and don't post in the 3DR radio forum.
