Tekin RS Gen2 Sensored Brushless ESC/Gen3 Motor Combo. This combo includes the awesome RS Gen2 ESC and the Redline Gen3 21.5 Turn Motor.  Redline Gen3 RPM Sensored Brushless Motors have been engineered to be smaller, lighter and faster than the previous model. Much more than a re-hash and new look, the GEN3 Redline Sensored Motor is ready for any situation and able to create the speed you need to win. On Road or Off, the GEN3 delivers smooth power across the entire RPM range you’ve come to expect from a Tekin motor.

The GEN3 21.5T, 17.5T and 13.5T are available in an RPM version as well as the standard versions. Designed for applications where higher RPM is more beneficial than torque, these motors are perfect for 1/12 and touring car racing classes. These motors come standard with 12.5mm performance rotors.

Tekin RS Gen2 Sensored Brushless ESC/Gen3 Motor Combo (21.5T)
I am a fairly newbie , I actually bought this combo just to try something different to my off road combos for an entry level for my first 21.5 class on-road build. However I had been racing 21.5 class off road 1/10 buggy with another motor combo and running slow. As there was a major meet coming up (before i finished the on-road build) i thought i would rejig the buggy gears, shocks, general set up a bit to see how competitive i could actually be. Then i though, why not, go the whole way and try this combo in the buggy (B5.1 factory Lite).
Its a new car. The response on the ESC in default mode is awesome. The performance is outstanding. I love it. I am a Tekin convert after just a couple of days.

ESC and motor performance are both spectacular.
Manual included with ESC is detailed and excellent. Programming is simple.
It runs very cool in my class with maximum legal gearing. It has a built in temperature gauge and logger.

It comes unwired. Some people may not like having to solder to the ESC posts. Look up Randy's soldering tips on team Tekin youtube and that will helps you a lot.
Warantee is void in wet or even just damp conditions. It rained on my major comp weekend. So I didn't run.
