I ran both an LL3 Tuned & LS3 Tuned this weeked and for me the LS was the better motor. ON track the LL3 had a slightly higher peak RPM and a could pull a little more gear at the bottom but the slower spool up made the motor overal slightly slower.

I would say the LL had more peak power, but a narrow powerband and slow spoolup in the middle.

The LS has a very broad powerband, faster spool up, and doesn't drop off as much when outside the ideal rollout.
