Review of Dragonfly Hurricane 2207 KV2500 Brushless Motor for FPV Racer from FPVmodel

Doesn't this motor look great?

Build quality of these motors from FPVMODEL look amazing. Especially when taken into consideration their price.
Quality/price ratio on this motor is huge.

Hope their performance in flight quality will be equal to their looks&build quality.
A great feature is also plastic ring along the bottom part of the windings that will prevent bolt, which is too long, to push against windings and damage the motor. What a great and simple idea.

Air gap is nonexistent and on the bottom side of the magnets here are blobs of glue used to balance the bell. Also, another important aspect is that vertical play is nonexistent also.
Bearings sound nice and smooth.
