I have been working on building a tri copter for some time now and finally have all the parts in.
I had everything working good with no RC TX, (just going through the telm).
After I hooked up my spectrum ar8000 with its own power hooked up I can't geting the APM 2.5 to do anything other then the LED's A,B,C RX, TX and Alive are on solid no flashing and I am unable to connect to MP.
I have been looking though the site for clues to what might be wrong but can not come to a conclusion. I am thinking may a blow fuse or a diode.
Any help trouble shooting would be greatly appreciated
