I need a new radio....

[lincpimp]

I use a m11 and a m8, both with spectrum modules and rx.

Seeing as the dx3r is the newest and greatest I would say to go with that. If I decide to upgrade i will go with it. I most likely will not upgrade as i have had alot of success with the airtronics stuff, and know how to use all of the m11's functions (that took a while to learn).

I definitely like 2.4ghz, much better than anything else I have tried. I bought the m11 for use with mech brake setups, but have since changed my mind and mostly use motor brakes. The flexibility of a top end radio is very handy. If it is only 50-75 bucks more for the r model I would say to go for it.
