Mini LST2 Going Brushless... What KV?

[Gregtxman]

Does anyone know a website that will estimate how fast my truck will go with different KV motors? I am staying with 2S lipo for now, but I want decent speed as well. I am thinking 7400 or 8200 KV Losi Xcelorin. I know that Castle makes an awesome product and it is not that much more expensive. Should I go with the Mamba Micro Pro instead? Has anyone ran the Xcelorin?

anyone have any info?

umm... were do you plan on running you car? because if you use those high kv motors off road it will overheat really fast and about speed I would look on youtube so at least you would know what to expect but I would think about 30-50mph depending on your gear ratio and motor you get hope this helps:D

High kv=SPEEEEEED, low kv=tourqe.
7200 good for both

were you are gunna run it will tell you what you whant to get if its gunna be like a track I would do like a 6400 if you are gunna run offroad run around a 4500 and if you run on road run the highest one you want;)

[Gregtxman]

I hope so... I am only running 2cell lipo, but Im thinking that it will hit somewhere around the 40 MPH range

What gearing are you using? Ball diff? Viscous Diffs?

I have upgraded to the Losi ball diff in the transmission, but thats in the driveline.
