OK on to the next phase of this project. Hybrid Diffs. I can get the cases, but I have to come up with the gears.

The Hotbodies gears are compatible with the RCM Hybrid cases. In searching for parts, I found this http://www3.towerhobbies.com/cgi-bin...?&I=LXLGX2&P=7

It appears to have a 50 tooth spiral ring. Would this be compatible with the 10 tooth pinion? Here: http://www3.towerhobbies.com/cgi-bin...?&I=LXJBM3&P=7

This combination would give me 5:1 diff gear ratio which is even better IMO than the 4.3:1

With the Emaxx, from input shaft to tire the ratio's are:
1st gear: 5.62:1
2nd gear: 4.57:1

5:1 is perfect! Power it with a AXI 4120/14 at 660kv and watch it fly!

It seems there is another issue with the Hotbodies pinion. Here we have a 8mm shaft with no hole? What's the answer to this?

Maybe this? http://www3.towerhobbies.com/cgi-bin...?&I=LXFWS2&P=7

I could turn the cvd's around backwards and put the dogbone end at the diff. Are the two compatible though?

Hmmmmm.........I wonder.
