V1, stock firmwear, low timing, 30% brakes, 12.0 cutoff. I have run it with a 1515/1y on 4s in a Tekno Revo, 8ight-T and LST2. Never changed settings, never disconnect motor wires, never look at it wrong. Just move it from truck to truck and race with it. Probably has 12-15 race days on it. No mods; fan still blowin'!
