B4.1 Brushless RTR for Racing

[Jordy]

I've decided to try my hand at Indoor Carpet racing at a track near me but before I Spent ££££'s on a B4.1 FT, ESC and motor etc. I thought I'd get the RTR brushless first and see how I get on this season.

The only things I plan to change are the servo & to use my DX3R & spektrum receiver instead of the RTR ones.

What are your guys thoughts? If I do use the RTR what are the essential upgrades to do.

Also what lipos do you recommend for club racing?
