I would have to agree 100% with you Ray, if you don't measure things and make sure all is well you will have trouble. Overall that could be said with nearly anything on a 1/12 scale car, that's what makes it so much fun
As for Adrian, the last sentence in your post couldn't be farther from the truth. Sure, the old front end isn't perfect but then again neither are the new ones. As per Ray's post this is why everything needs to be checked and checked again. I have been waiting for someone to make an old school front end (geometry and simplicity wise) that's perfect, perhaps machined even, for years. As for 1/12 scale on asphalt, I think most people would agree that while it's still alive carpet is really where they belong. To say that it works just OK on the rug is a big understatement.
How many Speedmerchant cars were in the A at the carpet nats? What about the 1-2 in Cleveland this year on an amazingly bumpy track? The proof is in the pudding (err racing).
