The media could not be loaded. I have been trying to make my own mini drones for a while and none of the motors I haves used have worked as well as these. The power of one of these motors was enough to lift the whole drone frame(this includes the other 3 motors) with ease. The wires are also very reliable and are well attached to the motor, so I trust they won't break unless u are putting them through some strenuous conditions.

I bought this for my Tello, It fits very well and had no issues what so ever, It performs like the other original motors. Definitely great product. For Tello, recommended.

First off, $15 is ultra cheap for two full sets of 8520 Motors. Second off, that is really really cheap when you consider how high of performance these are. These things do really really well with 55 and 65 mm props. Yes they do run a little bit hot, but they're still quite efficient. I have 6 or 7 packs through my first set, and I already know I'm going to buy more of these. They aren't the highest performing motors ever, but they do well and are a good balance between force and efficiency.UPDATE: it looks like I spoke too soon on these. After about 10 packs, three of the motors failed. They don't spin freely, and they suck down juice. I'm no longer going to recommend these even at two sets for $15. It's a darn shame, I really was hoping these would be more robustUPDATE 2: Crazypony reached out to me and had me send pics and vids. I did. They said they would work with me on a solution and then went silent. This is terrible.UPDATE 3: Crazypony got back in contact with me and offered a solution that I find reasonable. They tend to take care of their customers, and I will continue to support them ever with a couple of hiccups on items I have purchased from them.

I've been flying these motors on my micro FPV rig for over a month now. So far, here are my observations. I tested all 8 of the motors and they all worked, spun well with no issues. I have 4 on my micro FPV quad now and have put about 50 packs through it over the past month. Flight performance is great, the bigger motors really do provide more power but I have noticed that they get a little hot, especially with the bigger props that I'm running (not shown in picture). Overall, for the price, I'd definitely recommend the motors.

If you need to replace a motor for the Ryze Tello, these are the ones. I need to let you know, if you are replacing a CCW tello motor with black and blue wiring... you connect the blue motor wire to the tello black wire and the red motor wire to the tello blue wire. That is very important, as it deals with polarity. The two other CW tello motor wires are black and white. Those are matching and when replacing one of those motors go black to black wires, and white to white wires.

They worked great but the shaft size was to small for the sharper image DX-4. So the bottom gear was to loose so you will need to buy the gears also

Good replacement motors that last a long time. I would buy again. In fact I think I already have

inconsistent quality, lack of power that is to be expected being brushless and lower kv than my previous motors.purchased these just to revive an old tiny whoop while i waited on the new one, one of the motors rattled, and drained my battery quickly.glad to finally be on brushless motors, so glad......
