Bruce750i, currently I am using the two speed. I had a BB Revo that I used with a locked tranny and it performed well, I may need to lock the Slayer as well because the Neu 1515 supplies huge amounts of power/torque. I have tons of gearing options (Traxxas wide/close ratio gear sets, 12T to 22T pinions, 34T to 40T spurs), so I would like to experiment a little with the gearing before I lock her down. The two speed does have disadvantages for track/racing, as the auto shift can lead to Inconsistency (shift in the middle of a turn, approach to a jump, etc.).
