In my honest 2cents worth opinion, forget speky and buy a Nomadio React. its everything the 3r/s is and more. besides being 4 chnls. it has 40 models, multi mixing, abiltity to use digi/analog servos together, light and comfy to hold use, telemtry is built in and works Great with only the need to buy the sensors you want at 25.00 per unit, they offer a Temp sensor RPM/Tach Sensor, and a volt sensor when using an esc, plus the plug into the regular rx, just need to buy the acutal sensors and plug them in.

its only 260.00 for the tx/rx. additional rxs are less (85.00) than the spektrum units. i ve been 200 plus YRD away without any noticable delay in transmission.

IF you want a Killer radio without spending 450 on a 3/4PK or a Nomadio Sensor, the React is a Killer radio that has everything you could want and more as a RACER, let alone a basher.

plus you can plug it into your CP and use it playing DIRT< or Need for Speed or such computer games to boot. and make the game its own model and setup and save it so you never have to reprogram for the game. just move to that model and go...

my React has been one of THE BEST RC upgrades i ever got.
