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.
