C+D gears

[AlvaSpeed]

I remember seeing the specs of one of the Large Scale RC guys TT that he races with a different combination of C+D gears.


I can find that thread. I don't remember if it was here or in another forum.


What combinations are available?

Their MCD steel 23/26 gears , I've ran them for a year now, gives a slight difference in ratio by swapping them on the C and D.

Alva, here is a great gear chart, don't know if you've seen it or not:

Thanks, I have seen this chart before.


I wanted to know where do the other gear combinantions fall between the ones we are currently using.


I know if I use c26+d23 it is going to be a higher overall ratio. But how high? and how low with a c23+d26?

Here is a table I made for the complete gearing optionsI don't warranty the exactitude of the result in this table so if you want to make your own calculation here is the formula(A/B) * (C/D) = Total RatioLUMAX

I thought that the A?B set had to be a total of 60 teeth and the c/d had to be 50?? Will only having 49 cause any problems or are they cut differently?

The MCD 23/26 c&d combo work fine. There is one less tooth, but with a little slop they work fine.
