Somebody once said "be careful about what you wish for." I purchased a Cirtix Stock Club race + Ultra Sportsman 25.5T motor Combo. I put the combo in my VTA to test it and found out my car was going much slower than before. I gave the motor to my roommate who was able to test it with his SkyRC BMC-01 Brushless Motor Checker. His motor checker showed my S.P. 25.5 motor had about 1223 Kv. We tested a Novak Ballistic 25.5 motor in the BMC-01 Checker and it showed the Ballistic had about 1542 Kv. The Ballistic motor has +319 Kv advantage over the S.P. 25.5 motor.
The Ultra Sportsman and the Competition V3.0 are different motors as well.
I believe the Ultra Sportsman 25.5 was made to be a Cheap crawler motor. The Competition V3.0 25.5 was made with racing in mind and should be on par with the Novac for VTA.
