Today I was up flying - fairly open area - about 200' altitude and about 1000' out - open area - I got the "control signal lost" and it started RTH. No power lines nearby, etc. Only mods I have done are the WiFi extender TP-LINK Omni antenna for the WiFi extender. Otherwise the remote and bird are stock. Fresh set of fully charged Sanyo Eneloop Pro's in the remote too. Is this a reasonable distance to expect from the stock remote transmitter? I thought I read somewhere it was good for about one mile. I had the remote transmitter antenna perpendicular to the ground. Now I am a bit skiddish going too far out... Thanks - John.
