Ruddog RP540 540 Sensored Brushless Motor (17.5T)
Not bad a bad motor for 60 bucks. It isn't what my schuurspeed 17.5 motors are, but these are good for practice or just bashing imo.
My only complaint is the solder tabs seem flimsy and can move under pressure.
I'll update this when I get some more time on the motor.
UPDATE: Don't think this can be beat for the money. It's 90% of what the high end motors are imo. It's slightly heavier than the new ultra light motors 10-20 grams.

Ruddog RP540 540 Sensored Brushless Motor (17.5T)
Standard test with the SkyRC Motor Analyzer:
Max KV @2208, RPM @ 17,890, 1.2A.
Timing Average: 24 degree (27/20/26). Peak 085 dB.
Weight was 173g. Box contained nice foam padding not shown in video.
Limited on track runs, but so far I've been pleased with top speed and quickness, with no heating issues. Nice club motor.

Ruddog RP540 540 Sensored Brushless Motor (17.5T)
This is a very fast motor, more than enough for my beginner skill set. I kinda feel I should have bought a 21.5T. The leads are accessible and supported by heat-resistant fiberglass, unlike the melty plastic surrounding the leads on the motor that I never even got to use.
