I can't see it being a problem as were looking to encourage people to race and many will do exactly the same and buy a RTR car. I think you may need to get new tyres and you will need a lipo sack for charging.
Head over to
http://sorcinfo.org/ and you'll find the information on the series and you can also contact Dom the secretary for clarification.
Hope to see you at the track.
