[nitrostarter]

MC! Great job there! Nice finish on the chassis and battery boxes!!

I didn't see where you stated your gear ratio.

I'm not sure what kind of top speed you are looking for but here is how I ran my 1521/1Y 6s powered LST XXL:

Differential Ratio: 3.3076923076923075
Transmission Ratio: 2.090909090909091
Other Ratio: 1
Spur Tooth Count: 63
Pinion Tooth Count: 26
Total Voltage: 22.2
Motor KV: 1577
Tire Diameter (inches): 6.6
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor Coil Resistance: 0.008
Spur/Pinion Ratio: 2.42 : 1
Total Ratio: 16.7582 : 1
Tire Circumference (inches): 20.73 inches (526.66 mm)
Rollout: 1.24:1
Total Motor Speed: 35009.4 RPM
Vehicle Speed: 41.02 mph (65.89 km/h)

This was pretty quick for the LST and it's "MT" handling. Maybe your gearing is off? Not sure...
