Just few quote from Tekin support forum
"I agree with Canon. My R1 pro cogs about 1/2 throtle and this causes the car to become very unstable and throws the back end out. I am a bees gorgeous away from sending mine back.
The only light at the end of the tunel seems to be this firmware upgrade. When is Tekin help address the issues we are facing with the speedys in Australia? It seems that our batch came out with a firmware version that it shouldn't have? I spent 5 hours testing mine with different profiles and settings today. Nothing I did made a difference. I know that my motor is fine and also my radio settings are fine. They work well together with a Sphere."
"I received my R1 Pro 1 week ago and was very excited to go racing Wed night. Hooked it up as described to my Novak 10.5 and noticed right off the bat that the acceleration was very slow. Meaning you could hear the time delay it took the car to spin-up which is far slower them my Novak controller. I adjusted everything possible and was not able to change the start-up speed. When the races started cars behind me actually rear ended me because the car would not accelerate fast enough. Of course i did experience the cogging affect everyone is seeing also which from a stand still is tolerable. The part that is not, is if the car is rolling backwards it will not start until the motor has stopped. This effect and the slow acceleration are just not tolerable."
I got R1 pro for two weeks ago, I found it move backward then run at start up every time and it no respond for 3 to 4 seconds after a heavy brake or after a accident. I am playing with 5 cells and 3.5 brushless motor.
People could argue that it will be fixed soon, maybe, but even if it's high performance ESC the price seem to be a bit high and the wire is sold seperatly (I guess I'm too much used to CC stuff :P)
