FDR for SP v3 6.5T motor?

[Cardnim]

HI all,

My motor is getting quite hot (80 degrees normally) and I wonder if my FINAL DRIVE RATIO (FDR) is wrong.

Here's what Im running:
Schumacher Cat SX2
S.Passion v3 6.5t motor
S.Passion GT.2 (lpf) ESC
22t pinion
83t spur
33/23 internal steel idler gears

I cant find any info about the FDR for these motors either in the manual that came with it, or on Speed Passion's website.

Can anyone help?
Thanks guys.

Andrew.
