I am in FCC mode, but seem to only be getting 600'-900' (at very best, usually closer to 600'-700') control range (in all directions) before I it goes into RTH mode. I have flown around 12 flights so far, and have never crashed or damaged anything. When flying, I am in a park in a somewhat rural area. According to the manual, I should be getting 800m in open space, which would be closer to 2600'. Is there something I could be doing wrong, or something I could do to improve the range?
