It is very easy for a guy with Ebuggy to just yank on the throttle and drive the car harder than he needs to. Plus a 1900kv motor is still over powered on some tracks. If your running over 1900 then your not really driving a race car. Non of the pros are running anything over 1900. Many are going to 1700 for outdoor.
Just some info to think about. I have yet to smoke a plastic gear with a 1900.
In our part of the world, and on our tracks (medium-large, dusty, bumpy, real blown out dirt off road tracks), several of the best e buggy drivers have changed their 1800kv Hobbywing motors to 2200kv motors, because they felt that the 1800kv motor did not provide enough power.
My 9 year old son races e buggy and ran with a 2200kv Hobbywing combo with punch set to medium. Many told us it was too powerful, and we bought a 1800kv motor to try it out. On the two tracks, on which he is most familiar with and are consistently fast, the 1800kv motor gave consistently slower lap times.
The 1800kv was geared higher (a couple of tooth) and punch was set a notch higher.
He ran it for a while, but could not get his lap times down to his previous level.
We put back the 2200kv motor and instantly he was faster and back to "normal" level.
So, in our opinion, and several of the pro racers here, 2200kv are better than 1800kv, and definately 1700kv.
