78/28

If you wanted it to be a little more aggressive you can go with 78/29 or 78/30. It will bring down the punch a little but give you higher rpm's.. Just be careful to watch motor temps Without boost though you should be fine

Thanks guys!

It's definitely also about making sure the thrust balls can grip the rings, but the bigger gain you'll see in diff performance and life is when both thrust races are flat allowing the balls to roll completely free. The rings shouldn't be rough, you should just be able to see light hatch marks on their faces, no gouges or heavy scratches. Sanding the diff rings is also a very good idea for the same reasons.

has this kit been convereted to Metric?

Negative X2

So is the 4.1 temporary and is there a B5 in the works?

AE says no B5 in the works but I'm guessing that's a LIE!!! My hope and dreams are that we'll see SOMETHING new at the Worlds in Finland this summer. Even if it's 80% 4.1 with some "new" stuff on it.

That's what you dream and hope for?

Winning the lottery is in there too but a new B5 would do..

B5? duh, winning.

Sometime after Finland more my guess, why step into the world's with a unproven new design..

I think the losi 22 is what a lot of people are going to start working with. Just this past weekend at the races team darango from germany was here runnin their stuff. The new buggy that is still in the blue prints looks just like the losi. Mid motor and everything. Not to mention the kid won with it too

True, I doubt we'ld see a new car that's for sure. Worlds should be fun to watch this year. I don't see a for sure winner, I think there are 3 maybe 4 brands that all have 2-3 guys capable of winning. but that's me

rooting for AE of course
