Well i don't know what brand Radios you guys use? I use futaba and if you would take the time to read a little in the manual you would see that they say all you need is 100 ft. But i guess they don't know what there talking about ether. I have a few gas planes and i know a lot of people that have big gas planes and all we ever try to get is 100ft . I guess theres only 2 or 3 people in the world that knows how to do a range check. I'm sorry if i'm not one of them.


Thanks again
