Very sorry about the delay getting back to you, yes we have a beginners Gas class which runs every fortnight on a Friday night, while we call it RTR we let all novice drivers start there with not much restriction on the cars.
Once a certain skill level is achieved we encourage you to go up to the next class, Gastouer.
I don't know much about the R40 and I don't think anyone races one in the club, main thing with any car is parts back up and help. Being that there not common parts and advice may be limited.
Also to beware of advice from hobby shops, there are only 2 shops that have involvement with the club, Trackside RC and Toyworld Lawton, advice from other shops needs to be checked with the club, seen a lot of drivers buy stuff that is not much good for racing.
Next race meet is Oct 5th we start racing about 7.00 pm with entries closing at 6.40pm, best come out and have a look, I encourage you to do a little homework first this may save you money and you will most likely will enjoy it more.
