Could someone help verify these specs for me. BrianG at RCMonster.com has an cool web page with a bunch of useful info for brushless setup. One is the estimated speed calc.

Specs I gathered from the online XB-E manual but need verified:
Differentials
33t Ring Gear
11t pinion
(33/11) Diff Gear Ratio: 3
Spur & Pinion Gear (Manual has two pinions listed)
41t Spur Gear
10t Pinion
11t Pinion
LIPO Batteries & Voltage
(2) 11.1v 3s 3600mAh lipos
22.2v Total 6s Lipo Setup
Motor KV? XB-E listed two but I foung a seperate document for the motor B4485.
960kv Brushless Motor Specs seperate Documentation
1150kv XB-E Manual
1220kv XB-E Manual
Tire Diameter?
XB-E Buggy tire: 6"
PLine Excavator: 7"
I couldn't find a size anywhere for the buggy tires. I plugged the Proline Excavators size into the calc.
This is the output I got by plugging in the numbers bolded from above:
Differential Ratio: 3
Transmission Ratio: 1
Other Ratio: 1
Spur Tooth Count: 41
Pinion Tooth Count: 11
Total Voltage: 22.2
Motor KV: 960
Tire Diameter (inches): 7
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor Coil Resistance: 0
Spur/Pinion Ratio: 3.73 : 1
Total Ratio: 11.18182 : 1
Tire Circumference (inches): 21.99 inches (558.58 mm)
Rollout: 1.97:1
Total Motor Speed: 21312 RPM
Vehicle Speed: 39.69 mph (63.76 km/h)
Effective KV Value: 960
KT constant: 1.41 oz-in/A
Motor Torque: Amperage not specified...
Final Torque: Amperage not specified...
Final Power: Amperage not specified...
