I guess I'm the first to test very low gear ratio
I've seen it done before. That gearing is for extremely large tracks.

Champs is the best way to get Kawahara parts. It take a little while longer for some of the very hard to find parts, but they always get them. Plus customer service is top notch and they're english is pretty good. Never had any problems using them the last three or so years.

Here's directions on how to contact them:
http://www.rc-champ.co.jp/Champ_Inte...onal_index.htm

It's a different ordering process, but I tend to like it.
- Email them what you need
- They email you back to tell you if they have it or not (if not they'll get it)
- You confirm that you want to order and/or wait the parts to come in

BTW, they don't just sit and wait for the part you need to come into stock, they get them straight from the manufacturer and send them straight to you.
Some online shops said they could get me Kawahara decals. Waited months, until they said they were wrong and can't get them. Champs got them to me in less than 2 weeks.

Default dual diff setup

Hi Guys,

Any suggestions for a baseline dual diff setup? I was thinking 10k/30K.

Thanks,
Ralph

Thanks for the responses on the dual diff setup.

I tried to use the machined diff gears but they seemed too tight and locked up the diff. Anyone else have this problem?

Because you want it with stock setup, I suggest these:

Smaller diameter front tires,
Increase front track width to 199mm or 200mm
Increase front camber maybe -3 degrees
Increase front downstop, maybe 2 on hudy block
