Thanks nuz for your opinion... The difference in price between the two motors really isnt a factor when you are spending this sort of cash. neither is the weight i guess. But i guess i am worried that i will not be able to gear high enough to reach my desired speeds. but according to this gearing, it looks like i can just about considering the high speed idler gear will be installed.

Differential Ratio: 3.2222222222222223
Transmission Ratio: 2.215277777777778
Other Ratio: 1 + high speed idler gear should add around 8-10mph
Spur Tooth Count: 44 stock spur
Pinion Tooth Count: 25 largest pinion
Total Voltage: 22.2 ideal average voltage
Motor KV: 1600 neu 1520
Tire Diameter (inches): 5.5
Tire Ballooning (inches): 0.5 Hpi dirt claws on spi rims
Motor Current Draw: 0 not sure how many amps the motor would draw on stated gearing. would esc overheat????
Motor Coil Resistance: 0
Spur/Pinion Ratio: 1.76 : 1
Total Ratio: 12.56309 : 1
Tire Circumference (inches): 20.42 inches (518.68 mm)
Rollout: 1.63:1
Total Motor Speed: 35520 RPM
Vehicle Speed: 54.67 mph (87.82 km/h)

KT constant: 0.85 oz-in/A


if this speed calc is accurate then i would get the 1520 immediately. i need a motor asap... starting to get savage withdraw symptoms haha.
