Hi Jeff.

I'm not sure I agree with you changing from the CGM to the TC3, simply because the cars are so similar. If anything the CGM is a TC3 with the weak spots fixed.

I run both the Yoke which I race myself and the TC3 which my son races so I have had plenty of experience with both. They are both brilliant cars.

Now to answer your questions.

1. I have yet to build a car of any make that doesn't require at least some hand fitting. All I have ever done with TC3 diff cases is just not tightened the screws right up. I suppose you could play with the area where the bearings sit but that's about all. Certainly nothing dramatic.

2. Set Ups. If there's one car that's easy to set up, and easy to drive it's the TC3. The factory set up is almost right, and certainly a good starting point. I have prepared so many TC3s for customers and I now set them up all the same way, and they all handle perfectly - at least on our track.

Remember that almost all today's competitive cars have TC3 suspension geometry. I measured up my SD and my son's TC3 recently and if you put the 2 diagrams over each other you will see that they are almost identical. The HPI Pro 4 too has identical geometry.

The only problem in the States is that Yoke have a very small team of factory drivers so really good info is not so forthcoming as is TC3 info. As somebody already said Blackstock and Baker's set ups are readily available and these guys are quick.

But really, in my mind both cars are ballistic so I think you should go for whatever is best in your area in terms of parts and race information availability - which is probably the TC3 anyhow !

Sorry if I've confused you even more. And just to confuse you even further I can tell you that son Josh will do identical lap times with both cars - about a second and a half a lap quicker then I do with my own car !

Whatever you decide on, I can help.
