Just bought myself a Tekin RS PRO after 3 years using a LRP Sphere TC.
I find it a very impressive controller, especially the smoothness surprises me.
But there are a few problems;
I'm running 1/10 TC modified and I'm using a 4.5t Speed Passion (V2) motor on a large 1/8 scale open track. I used to do this with my LRP controller. After my run with the LRP the controller was cool/warm maximum 68F/30C, batteries warm/hot 104F/40C and my motor warm/hot 160F/70C. This was ok.
Now I'm using the Tekin RS PRO. I ran a smaller pinion than I was used to do with my LRP ESC, as this has been advised. Result: Lack of top speed and too much revs (like you would normally expect). A buddy of mine changed the settings using the Hotwire and increased timing boost to 5 and start RPM was near 5000 RPM. This didn't help much. To be honest wasn't planning to mess around with timing and turbo etc too much since it's modified.
Finally switched to a larger pinion and kept on going every few runs until I almost reached my normal top speed (I use this as an indicator). Still I would like to go up one more tooth (to reach my normal top speed), but temperatures tell me not to do that. I'm now running 1 tooth extra on my pinion than I would with my LRP!
Temperatures after running with the RS PRO:
Motor and lipo are ok, but ESC is too hot. Almost all indicators lit up (can't remember how many). I have a high RPM cooling fan installed that is cooling the ESC solder post, but still the ESC is hot. I also changed the standard capacitor to a 16V 4700uF one.
Point is: My car lacks top speed and ESC gets too hot.
Other relevant settings V203:
drag brake OFF
brake strength 100
neutral width 10
th profile 3 (linear)
push control OFF
timing boost 5
Could it be a faulty ESC?
Do I have to use dual mode maybe?
Am I doing something terribly wrong?
Hope you guys can help me out...
