I had a look at using the standard screws for Parma rear wheels but only a very small amount of thread actually goes into the hubs, have you had any problems with that at all? I would like a little more thread in there if possible so maybe longer screws cut down to the right size?? As for the front end tip, you know what, I did exactly that with the CEFX car, so why did n't I think of that with this? DOH!! I will hopefully get to run the car this weekend at Torquay, next weekend is the Plymouth winter series race and the weekend after that is the Plymouth national. Hopefully it'll go in a straight line and turn both ways by then. Feel free to come over and say hello mate, I'll be the one scratching my head trying to get his new 12X setup right! Cheers guys, Chris.
