Sounds like you want onroad 1/10 scale.. since you did say RS4..

The HPI is a great car, I owned one. But common wisdom around here and the local track is that its great for bashing and non serious racing. IF you want to race, get a TC3.
I haven't driven a TC3, but I'm guessing that it just handles better!

The RTR kits are right around 300, but think about the kit.. you might like the 2 speed transmission for the added cost! It definitely is worth it!

Btw, please dont use misspelled cuss words! Its against RCU policy!
On that note.. welcome to RCU! I hope you enjoy what RCU has to offer.
