Yeah i agree on the torque sleeves.............i take em off too, it gives a few thousand more rpms and lets the motor cool better IMO. Here are the ratings on the EVX2 esc..............not sure what the 30amp part is either, it shows a "rated" current of 180....?

Input voltage: 6-14 cells (7.2 to 16.8 volts DC)
Case Size: 2.27”W x 2”D x 1.05”H
Weight: 3.6 ounces
Motor Limit (540 size): 10-turns
Motor Limit (550 size): 12-turns
On-Resistance (@Trans)–FWD/REV: 0.004 Ω / 0.004 Ω
Rated Current–FWD/REV: 180 amps / 180 amps
Continuous Current
(@100°F amb.): 30 Amps

Better props help too with speed...........less flex if you go with octura's or similar and they can be finely sharpened. Altogether with the higher gearing, 14 cells, water cooling, torque sleeves off and sharpened and balanced octura props you will basically have all the speed you're gonna get from a villain with stock motors.
