thanks a lot, Johnny.
just to clarify, if I make a flat graph, all bars are on the top (low frequency), the boost would kick in too early. is it right?

Thats correct, you would never let the motor get to that freq range for the boost to kick in.

Not to be mistaken but one curve won't be good for all the different classes. Where a TC seems to need the torque at the start to get the car going and thru the infield for driveability and the finally the boost on the straight a 1/12th probably can get away with much less torque at the start but then could use a little more for the infield and again the boost on the straight, so a TC profile would look like it starts out high and flat and then eventually tapers to low freq for the boost to come on and a 1/12th profile could look more like a camels hump, although being careful not to have the mid peak so high that the torque is coming in and snapping the car out in the corners. Again these are JMO, please feel free to add to this if I'm right or wrong.

Hi Johnny,
I run my 1/12th on asphalt and run a 5T motor. I use the Kopropo profile.
Do you have a esc curve that you can post. Do you recomend in terms of brakes frequency and drag brakes.
Thanks

Thanks.

Sorry guys I just don't run low turn or mod motors so I can't help you out. Maybe someone like Drew or Heibiki will have something, but I don't know if they run 1/12th.

The thing is to try a profile that looks like a camels hump, but start it off about in the middle of the freq, if it hits to hard on the starts, drag the AVG bar down till it doesn't hit as hard and then go from there. You might have to tune a little for mid field and start of timing boost, but it should be pretty simple.

Thanks mate, first look at it its quite different from the mod 12th setting from the Ko website... Cant wait to try that!
Why doest the curve start at 3.38... which I think high...?

Thanks again can you just descride why the curve starts at a high frequency and then comes down to low frequency and back up again....?
Cheers m8

Getting better, but I'm looking for a tekin rs killer profile for 17.5.

On another note, I am running fanless for the esc, but wondered if heat will gradually make the speedo slower during the race. I also heard that the esc fan is mandatory for boosted applications. Is this true?
