I know Futabas are great, I'm actually switching from Spektrum. I've never had any range issues with them, I just had a glitching problem with some signals at our track and turns out only people with spektrums were having that problem so I switched. I went with the R2106GF, it's going in my mini 8ight, and by the time that thing gets far enough away from me for there to be range issues it'll probably be impossible to see lol.
