Brushless Touring Car Questions

[Sower]

Right, this isn't for racing. Although it's the TT-01R with the bearings, oil shocks and a few other hop ups. I plan on using it for drifting and just playing around. The reason I was looking at the 6900 is because there are two new ones on eBay for $60 each. Plus I already have a MM esc.

Ultimately I would like to go higher voltage vs. higher amps, but it's not like this is a racing car I'm trying to optimize like my truggy. I was thinking of getting a 2s 3500 lipo with the 6900.
