RTR competitiveness?

[sefton]

thinking about coming back to RC racing (after around 10 years out)

however I don't want to pump something like 1k into it again.

before I sold up brushless and lipo had just come on the scene. I guess lots have improved and changed since this time. (hopefully less faffing around with cells etc)

I was just wondering how competitive a rtr (like a RB6) would be these days? against a custom build with medium/good electronics.

I guess the servo would be slow?

I used to love building the cars - is it possible to build a similar spec as an RTR for the same money?

thanks
