No an R version is not available yet and probaly not anytime soon but who knows. I pieced one together and The only things not available from Tamiya yet is a carbon fiber rear shock tower and carbon fiber chassis although you can get those parts from 3Race. The car handles fairly well for 17.5 although I haven't tried anything faster. The torque steer isn't noticeable although you do need to spend some time balancing the chassis especially if you run lipo.
