Since up grading hardware/ software I now have an intermittent problem with my Rx TX. PV2 flies great for a round 1.5 minutes then losses comms ... goes into safe mode and returns with Rx TX every now and again making communication till around 5 minutes with them both turn on where all communication stops. If I turn both off for 10 mins and they will communicated for around the same time as above and stop again. I have down loaded all the new hardware and software 3 times and its still happening. If I leave the phantom on and turn the Controller off I will not get a re connection but if I do it the other ways around I will get a re connection which tellls me it the Phantom with the problem in receiving . Any advice would be helpful as there are not too many of these in New Zealand !!!
