I race 13.5 boosted spec which puts the motor under quite a lot of strain, this class pushes the motor to the max as we run a lot of boost and turbo. I ran Fantom last year, I know the braking changes from motor to motor but the braking is still behind the LRP in this area, everything else is excellent though, hopefully with Jan Ratheisky on board he will help develop the software as I know he does a lot of 13.5 blinky racing
If you are creating alot of motor heat it doesnt matter what you do the brakes will be soft it might be better with the LRP but dont forget the LRP esc acts like an on/off switch thats fact.Get the temp down and you will see the brakes will return.
