M17 2.4GHz Ultra Response Mode (SUR) FH5 4-Channel Radio Transmitter w/RX-491 (RX491) Waterproof Receiver & 1S LiPo Tx Battery Pack

My previous radio that I'm now using for non race vehicles was a Spektrum DX3s.Never had any issues with that radio but could tell I needed something better.Even with super fast servos the response seemed like it should be better.Other drivers had mentioned the Sanwa was a lot faster radio but was skeptical.Well the M17 changed all of that and was Very noticeable on the Black carpet track.I had to be careful at first not to brush the boards because it was turning faster because of the faster response time. Now that little flick to avoid the boards when you mess up your line actually works now.

I like the controller fine I use it for no prep drag racing and only use a few functions so for me it was hard to spend the $600 for no more than I needed it for.

This thing is worth every penny. I have it bound to all 9 of my rc cars! Also got wireless charging adaptor, so it can charge on an iPhone charging pad. Easy to use and set up, and bind to multiple receivers.

Raido has excellent software but feels cheap compared to my FlySky Noble Pro which is all aluminum & $200 cheaper. Overall though, I do like the M17.

Well worth the money

Very easy to use, and works excellent.
