So I'm looking to purchase a new racing motor for my E-buggy and I'm set on one from Hobbywing, as I have a Hobbywing ESC and I want to use the full-sensored mode that the ESC offers.
Up untill now I have used an 'ok' off-brand 2000kv motor with fairly weak batteries.
I'm looking at either the Hobbywing 1900kv motor or 2200kv motor. I know most of you are thinking "1900kv is king" right now, but hear me out.
I don't race on your typical tracks, especially the ones you see in the US. I race on everything from tight dirt tracks to crazy grip astro tracks to a HUGE multi surface track with a 100m straight.

Now to the actual question: What would be the better option: Buying the 1900kv and changing the gearing for the different tracks OR buying the 2200kv and changing the gearing + turning the power down/up on the radio.

I know 2200kv is overkill but I have a feeling 1900kv might be 'underkill'. It would seem that the 2200kv would give me a little more versatility, but Maybe I'm seeing this wrong. Anyway I'd like to hear your thoughts.
