I am only getting about a 1/3 of a mile out of my spektrum dx6i (with 6200 rx) and I lost my plane .
Thank God I was able to recover and use the electronics.
I fly next to my house where there is an open field.
I think it could be the 2.4 gig wireless networks around my block.
Or could be that the new spektrum dx6i is to week and I need to go to a dx7.
My video 900m transmitter did great and had no errors or any problems.
motor kms 380
esc castle creation 40amp (i think)
