I think those guys have it right.... I know we would all appreciate a radio that made 4ws easier to use. Honestly, I don't see alot of guys being interested in a higher priced radio as the typical Nomadio, since range and interference are not typical problems for crawlers. I run an M8 w/Spektrum, but that is simply because it is what I use on my other land based RC's... not for any advantage that the 2.4ghz gives.
