Ludo, if the torque is a little to much, what you can do, is mix some motor with the ESC timing, as long as it don't go above 30' in total, it is a good way of tuning. Adding some timing to the motor takes off some of the rip, and gives you a little more RPM, and then the added ESC timing, tops that up.
But glad you liked it, imagine what it is like, 10.5, carpet, foams, additive and 1400g weight...!!
