Gearing, motor kv, and heat question....

[Finnster]

If you can't find a spur/pinion ratio that you can use, and don't want to change motor& batts, you can always swap in truggy diffs and lower the FDR that way. that savage diffs are crap anyway.

IDK how you put the CD in, but a huge spur may stick way out the bottom or hit the sides or such.
