That was like 6 weeks ago (kyosho), and you switched to Losi-and now you're already switching again..Good luck with AE cars..

The Losi was horrible.

Hmm, I gave seen quite a few on the for sale board, did you sell it? So, now you are running B4.1, T4.1 combo, hope they work out for you..

I'm starting to think that all the brands are equal but all the stud-muffins drive AE.

my friend took some photos of the top and bottom of his car, I put my car next to his and I would say its about 3/16 longer than a stock b4 chassis, he took a 2"x1 1/2"x1/8" CF, 4 countersunk screws on each side and put some sort of glue on the bottom of the chassis to stick the 2 peices together.

Guys,

I did a search, but did not find much. I am thinking about switching from a ball diff in my FT B4.1 to a gear diff with silicone fluid. Is there a specific area/thread for this topic?

Or...can anyone recommend a starting point for a gear diff with silicone fluid on an indoor clay track?

Thanks for the help!

What kind of tires are good for grass with the b4.1?

on my rtr i used either 50 weight losi shock oil or 2k fluid it worked the best,why would you switch the ball is so much better.

Just looking to try something different. There are a couple guys at SDRC running the gear diff that are more than fast with it, so I think I can make it work. I have one lying around and just wanted to tinker with it. I like the ball diff, but rebuilding it after every race weekend it getting to be a bit much.

Thoughts?

Every race weekend? Something is not right.

It sounds like you are doing something wrong if you are rebuilding a ball diff every weekend. Mine would last a few months before a rebuild.

you dont need to do that, the gear diff fluid if anything wears out quicker than the ball diff about 4 racedays. maybe.

+1 i dont rebuild my ball diff more than 3 times a race season

Any suggestions?

I usually rebuild mine 2-3 times a season, or before a good sized race, people must be running their diff's too loose that they are burning them up so quickly..
