too much stress?
Well in that situation you can loosen the slipper a bit, use a less powerfull motor, or indeed use a less performant lipo.
Over here in Belgium, some of the best 2WD-drivers use only a brushless 9.5 or 10.5
a 7.5 will do also. A 23-pinion sounds ok, but it also depends on the track.
