Default Final drive ratio?

Hi guys,
Excuse the silly questions as I've been out of the rc car loop for quite some time.

How do you work out the final drive ratio from roll out?

It's just the losi manual gives recommended rollouts for different motors. I have a speed passion 13.5 and GT2.0 and have no idea where to start gearing. The package for the motor gives a recommended fdr and the speedy is recommended to be geared to a lower fdr (higher numerically)

cheers

Assuming you are running rubber tyres just divide 200 by the rollout and you get FDR.

Default Ceramic Diff Balls

I'm looking at purchasing some ceramic diff balls for the Type-R and wanted to know if anyone has any experience with the 3/32 size versus the 2.4mm? Also, does anyone have a particular brand they have used with some success?

Thanks in advance!

I got some none brand name ceramic diff balls on mine and it felt better right away! I bet ya any brand ceramics will make your diff feel better.

Default Diff ring size

any one tried this?
http://www.bfastrc.com/losi.html

I want it to try but didnt find one for the car yet, does any one know if non keyed diff ring is same size as ASC one? or other Losi kit?

if they dont make a set I like to order one set of keyed rings and another set of non keyed rings to make up 2 set in case I want to run front diff oneday.

Quick question for you Type R guys, I know alot of you have been using some type of Corally wide front bumper on your type r's and I've done the searches and have not been able to find out what bumper you're using.

Any help would be appreciated.

Thanks, Jesse

Dragonfire --> Well done! A lap over the whole field is very impressive... Care to share your setup with us?

Just finished the WA Electric State Titles and managed to bring home a 4th in 10.5 amongst a field of XRays and 2 Tamiyas... Was also the only one running an SP10.5 too... I'll post my setup in the next week or so when i get some time.

Don't know if anyone has seen this http://www.rctech.net/forum/electric...ml#post5653811

It's already has the Type R model installed. Good tuning tool.
