I should be gettin' my 7xl in this week from mike..

I'm goin' to try 22/66 gearing... 6S lipo, 22.2 Volts

51000rpm (motor)
3:1(Spur to pinion)
2.77:1 (1st Gear)
1.81:1 (2nd Gear)
3.31:1 (1/8th diff)

multiply 3 x 2.77 x 3.31 to get final drive ratio for 1st gear
multiply 3 x 1.81 x 3.31 to get final drive ratios for 2nd gear

I have an ms excel sheet that does the calculations, PM me if you'd like me to send it...
