RCM Available gears

[BrianG]

I'm trying to figure out what gear set I want to use on my E-Jato project. I'm not sure if I want to go with Mod 1 or stay with 0.8 pitch. Mod 1 has thicker teeth for durability, but the Jato is so light, I don't think that will be an issue.

Anyway, the problem I can see is that the transmission doesn't leave much room for a variety of gearing options. So, I need a fairly large spur. The Revo spurs go as high as 40T, but are not very big around. So, I need a large pinion to give me the room I need. Besides, I want a spur-to-pinion ratio of about 2.2:1 or 2.3:1. At 40T, that's an 18T pinion, which aren't available for Mod 1.

Soooo, I figure I'll stick with 32p. If I stay with the 54T spur, I need a 23T or 24T pinion, which also aren't available.

I can't go with a smaller spur because then I get tranny clearance issues between the motor and tranny.

Argg. Any other ideas?
