2212 920KV Brushless Motors CW CCW for F330 X525 F450 S500 F550 S550 ZD550

I built my own pixhawk based drone. I used these motors with the recommended 10"x4.5" propellors and 30a PWM ESCs. The motors are decent work thus far are working great. The kit came with 2 clockwise and 2 counterclockwise motors. The motors have bullet connectors on the end which fit quite tightly with my ESCs. Overall I would highly recommend these motors if your trying to build a quad.

I love my new bright red motor. It has the power to lift a large drone I'm building with a 1045 prop and a 40amp esc (might be a little overkill), but the windings look nice and tight with a very thick wire that looks like it can hold a lot more current than it's rated for. Also, the bearings on the look great; they have a very smooth feel, and the casing is a thin light aluminum, which is ideal for people who like to fly their drone on the edge (it makes me feel better than saying crash a lot).

Motors are ok. I am using 4x of those for my X525 Frame with 10x45 props. *BUT* Had to re-solder two motors connectors (total 4 connectors fixed), they came with a really bad solder job, I could tell whoever did the cut of the insulation prior to solder, also did cut 4 of 5 conductor threads. So those two motors had no "punch". Made me lost maybe 4 hrs, after checking/recalibrating ESC's, Removing heat shrink (which by the way was correctly installed, hiding the problem) After the solder job, Voila! Honestly, I don't know if will order again, still mixed feelings, the motors have endured a pair of very ad crashes without any damage. Maybe luck ? Maybe they are sturdy?

I have purchased this set of motors twice now. The first set went towards a 9" quadcopter and those motors worked flawlessly. I especially appreciated that the motor shaft was very thick and so it never bends during any sort of crash. This did require me to drill out the hole in my prop, but well worth the extra durability in my opinion. My second batch of motors wasn't as good, as one of the motors was dead on arrival. I did not use the motor until 2 months after my purchase, but I reached out to Readytosky through the Amazon Customer Service Chat and they send me a new replacement motor. The new motor arrived within a week of my notifying them of my issue, which was very nice. For additional information, the ad motor I received would not spin up fully when connected to a known-to-be-good ESC. It would start spinning slightly, but never go to the full speed as one would except. The replacement motor worked perfectly however. All in all I think these motors are a pretty good deal, especially knowing that Readytosky will replace a faulty motor should you receive one.

One of my motors came broken but the seller replaced it quickly. One thing to look out for is the propshaft is way too large for most propellers so you would have to use the same company's 1045 props. Also make sure you have your own screws because those arent supplied. Otherwise, the motors deliver good power and are excellent quality. They worked well in my Eclipson Model A 3d printed plane which i crashed into many pieces

No complaints. I needed only one as a replacement. Works fine in custom px4 drone on phantom 2 base, I dont feel any difference between this and the original dji 2212

Cheap motors. Only lasted for 14 flights and all 6 motors are making noises and grinding. 2 motor shafts are loose and have play. These motors are not a good choice for a hexacopter build. My opinion they are a beginner's motor for a small build.

I have put 5 stars for durability, however, I'm not sure I have had them long enough to tell. They seem really good so far.
