DH 9116 Pinion Gear Spec


Is there anyone who knows the pitch of the pinion gear. Its the only piece of the puzzle I don't have. 8-T / 2mm shaft Dia. / pitch ?. I found one on ebay with a 32 pitch. Thought I'd give it a try if the pitch was the same.

Below is WRONG.

Closer inspection shows its not any of the pitches that were from
my RC car days.

A 48 pitch 1/10 scale car pinion looks like it meshes but it's slightly off.

Sooo, I don't have a clue.


I will find out. I have every pitch ever made from my RC car days.
I'm guessing it's 48 without looking.

Yup. A 48 pitch pinion and spur I had in my parts box mesh perfectly.

I made a diagram for future reference.

I hesitate to comment - I just know someone here is an expert and won't like this answer.

An easy formula to calculate the pitch is divide number of teeth + 2 by the outside diameter.
A good reference for all the formulas is here.

There's a couple different ways the pitch is given - like on the walkera helis it's given as .4 mod. There's a calculator to convert them here.
