Just installed mine last night and tested it today. I'm a little disappointed as I'm only getting out to about 2500' before RTH kicks in. The most I ever got from stock was around 1800'. So it is an improvement, but not as much as I had hoped for. Maybe I did something incorrect during the install. Is there anything I should check? I followed the instructions to the letter. I'll hopefully test again in a different location later this weekend to see if it's just interference limiting the range.
