clutch bell DP info
 

Im currently messing about with scratch build models and just wondering if theres a commonly used DP for the spurs etc on nitro models,

0.6 0.7 32 48 etc etc Im trying to make sure that I can get the right final gearing range that I need and compatible spares etc

been looking at 1/10th clutches and bells, traxxas seem to do them up to 22t

but nowhere seems to ever mention the DP as I suppose you just buy the parts as per the model you need

The dp for all modern 1/8th off road car main geats is Mod 1.

An easy way to determine diametral pitch DP, add 2 to the number of teeth and divide by the outside diameter, this can be a bit of a guesstimation if it is an odd number of teeth.

P=(n+2)/OD

oh cool thanks guys, excellent help from both of you.

scratch building stuff is great fun,but wanted to try and avoid any last minute problems especialy as its my first nitro motor toy :)

will print and laminate that formula for my pitbox, very helpful

now off to egay to search for 1/8th clutches and mod1 spurs

:) very happy
thanks:thumbsup:
