hi all. what is the differnece in the Hyper 7 PBS and the Hyper 7 PCR? Is there any differnece between speed and overall performance? And which is the BETTER one out of these two?

Also, does anyone know what is required to turn the Hyper .21 8-port engine in a pull start engine, so i can use both starter box and pull start, and the price of the items required?

And does anyone know any good UK sites that sell hyper 7s, accessories and everything else for a nitro car?

thanks everyone!
sorry for asking so many questions!

The only diffeences that I could tell off the bad between the two are the PCR has Laydown Servos and a Pull start on 8 Port. The PBS has upright servos(better imo) and no pull start. Sounds like you might want to go for the PCR if you want the pull start. Both speed and performance wise are the same, unless you get caught up in that whole "lower CG" thing. Which is BS!
