    I have swapped my Racerstar AirA 2508 1200kv with these ones (1300kv version) and have mixed feelings. What I like: -Nice looking finish -big bearings (brand unknown) -thick wires -spare bell housing screw and shim -good price What I don´t like: -poor balancing -quite heavy for it´s size (~55g with wiring) -no spare rubber o-ring (~4x0.6mm) and shim that is placed on the shaft between bell and stator (already lost one) -less efficiency than my AirA (~10% less) on 7” props during hoover They are a good alternative for the AirA motors on 7-8” long range builds. If you like little bit more power and authority go with these motors. They are also more durable due to bigger bearings. On 6S you can even do some serious freestyle. If you are out for max efficiency go with the AirA´s
