Wondering what others are getting for flight range on there fc40's I read some posts that suggested if I put 1 of the phantoms antennas horizontally and the other vertical was the best range and took her out as far as she would go in a straight line at 300 feet high and then looked at the video to see how far she went and looked on goggle maps and seen it was exactly 300 meters before she stopped and wanted to come back from being out of range of my tx I then put the antennas back the normal way and I got 320m tho it was a lil bit better to get an extra 20 meters. It still seems far short of the 500m it should get in FCC mode on the transmitter. My battery's should still be pretty fresh still i'm using energizer 8x life litho AA's and I'm at 1.6 volts each. Or 6.4v for all 4 tho I never tested them when they were brand new to see what there starting volts were. and wondering if that is still high enough to be getting the best range I can get from the TX.
