I dont know why but I have found myself in the frenzy of a build using parts I have had sitting around for a while. The body sits nicely with no binding on the chassis, the chassis rolls smoothly on four wheels, the guide turns freely without interfering with the nose. I have followed the 2015 VRAA rules for the 2.5 class but if changes happen I may be able to take advantage of them. There are a couple of small additions to make to the chassis but all up weight with a motor is 64 grams. So once paint and other details are added I should be above the 65g minimum. I know this is no "Chris Walker" but I am happy so far....not that much cussing while resoldering a joint or remaking of parts.
I have been reading up on car specs and you are correct in focusing on my final drive ratio...it needs to be taller, longer or higher. A change of pinion and/or crown will take place before the Vanwall flies away.
I have my car packed and ready for the Post office journey to Canada for the start of the VRAA. Now I look at the pictures I see a detail I have missed but....it is just too bad now. I have no idea how it will run compared to others in the field. I think the motor is a little "soft" but it handles well.
