I found that a linear throttle curve was a problem because I have a "heavy trigger" finger. IIRC at the 30% point hold with the left mouse button and pull down so that the results is a soomth curve upwards.
Well, this is one thing I notice with the Tekno conversion. It utilizes the stock Revo clutch which allows the motor to rev up before actually having any load on it at all, which would reduce cogging quite significantly, if I'm correct.
