I'll stick to the bullet points to keep it short. It's a non-v P2 I just replaced my 200mw trans with a 600w/Immersion. It looked great on the BP 7" monitor Hooked it up to DJI Assistant like I always do. It worked fine. --I suspected the compass might be a little off due to the fact after I had it on the bench for a while I noticed the quad was near a magnetic screw holder. The Mod setting was just a little out of range so I watched a video and was going to do the fix which consisted of moving a magnet around the quad. I went to switch to a longer PC to quad cable which is a little longer than the one that came with the quad. It fit perfectly and I swear I have used this before but I may have gotten it mixed up with another that looks just like it. All of a sudden my quat starts beeping. There is no gimbel calibration movement The software no longer recognizes the Phantom. Is it possible that since I was just under the hook to wire the new transmitter up that I didn't secure something and it is a coincidence that it comes apart now? I know that's wishful thinking. Anyway I hope some of you guys can lead me in the right direction for troubleshooting. Where you at Jason?????????????\ Fully charged batteries. Thank You All Oh yes, I do have the gopro inthe gimbel and yes I do have the antenna on the Transmitter.
