So I run the Castle Sidewinder 3 in both my RC10T buggy conversion, and also in my B4. Same exact setup, they also both have slicks for the clay track.

The big difference is that the B4 has a gear diff, and the RC10T has a ball diff.

What I have noticed, is that the B4 is a hell of a lot faster, and I'm not talking just in the corners, it's on the straights. It lights up the tires anywhere on the straight if I hit full throttle. Actually it does this anywhere on the track, which usually loops the car around.

Whereas the RC10T, when it doesn't wheelie, it's WAY more controllable on the straight. Or just more controllable everywhere, and WAY more forgiving.

They're both geared so they don't run hot.

My guess this would be linked with the weight and tire size differences. I also believe the Associated Trucks have a different gear ratio. Hope this helps.

I'll say it again... your T Buggy conversion is pretty darn cool as-is.
There are tons of variables there besides the differential. Same wheel rate, weight, and weight distribution? same camber, toe and anti-squat between the two? Suspension geometry also plays a big role.

I *REALLY* love driving the T-buggy. It's so much more forgiving than my B4. Plus it's fun to surprise some of the newer guys with just how good an old car can be.

I know there's a TON of factors that could play in why the B4 is faster than the RC10T buggy. They run the same wheels and tires, so that's out too. I think it's just progress, little things here, a few things there, and so on for the B4.

If you just want to have a happy fun time, you take the RC10T buggy, if you want to race with your pals, take the B4.
