2200kv MMM

[nuz69]

No. A 1512 1.5Y will short your runtimes if geared for the same speed, because it won't be efficient at all in a truggy. The motor is too short. The runtimes don't depend of your motor, unless its undersized, but of your voltage, your gearing and the weight of vehicle.
To increase runtime you need to increase efficiency, if you cant change your motor, you need to up you voltage and reduce the gearing, to keep the same power and reduce current.
More over your timing is not right for Y windings. Best efficiency with the 2200kV 1515 1Y motor is 4-5, not 0.

==>Try first to reduce a little your pinion, set the correct timing. Punch at 75% is good, you don't need more power at start.

A Castle 1518 1800kV will be more efficient in a truggy on 4 or 5S, and the 1520 1Y 1600kV on 6S with low gearing would be the best solution ever to have insane runtimes, but I do not know if the rules permit theses motors...
