Rx connection dropping all the sudden

I am having an issue and am not sure why it is happening.

I switch flightcontrollers from librepilot revolution to the pixhawk. I also have the 915mhz telemtry radio other  those 2 things everything on my quad is the same. I am running a frsky xjt moduel and x6r rx. Never had an issue with dropping connection with the revolution FC. 

It never happened in flight so far but i only have a couple tuning flights. On the pixhawk so far. There have been a few times where the transmitter wouldnt connect to the rx i would move the transmitter around and it would finally link up. 

Well i was just outside auto tuning the pitch axis and everything was going well i went to correct some drift and no response. I didnt even get a voice alert telling me that signal was lost. I was 10ft from my quad. It ended up crashing into my neighbors house broke 2 props and knocked my gps puck off the mast. Thank god nothing else broke. I have over 1k in this thing and that would have sucked. 

So my question is obvious why am i losing my link to my rx with the pixhawk? I didnt set up failsafes yet because i am not flying more than 20 feet from myself, like i said i am tuning and testing. Didnt think i would need them quite yet. Rx is powered from pixhawk. Pixhawk is powered from power module. Any ideas on this?

  • Well just found out that the crash destroyed one of my motors. It has an internal short now. Not sure why I am having issue with RX connectivity  with the pixhawk but oh well I guess. Quad is grounded till I can get new motors! Sucks ass!
