what pinion?
 

b3 with original stealth transmission with 81t spur wondering if i should be running a 24 or 25 tooth pinion with an lrp vector stock spec x11 10.5 motor and lrp sphere comp esc

cheers!

I'd also like some gearing ideas with a 9t ezrun combo and 78t/81t spur, what pinions to try?

pinion
 

me too please. I have a 6.5 80t spur.... what is the best pinion for that, regards.

I think 24/25 is about right in the B3. Maybe a little higher with a 10.5. I use to run a 7.5 on a 24 and that seemed about right for me.

9t maybe 22?

Ray you have a Cat SX... 22 for outdoors. 19/20 at ludlow

Thankyou Big G. Are you going tonight ?

nope

anyone have any ideas on the pitch - i know im looking at 24/5 teeth for the b3 with a 10.t motor but no idea on the pitch!

Should be 48dp

thanks

does it matter which brand all i see on ebay is hpi or tamiya - i guess as long as pitch is right and they are made from a durable alloy should be okay?

are the hollow ones any different to the solid ones as some seem to have some weight saving and appear hollow on the outside of the gear

cheers!

Any should be fine
