I like the prop mounting over the 5010s. Would love to give these puppies a spin around the park but the bank account say No.

Looks like they have used the same small bearings like they use in the 2836/11 motors. I hope not as they do not last. I've bought dozens of motors from RCT but the quality seams down a bit over the last 6 months.

Ill try to post asap though I doubt if it can bee seen, I really dont know why it was bent you can see it evidently when its turning specially when the screw is on it.

tested vibrations with my ipad (iseisometer), and its conclusive that vibrations are present with the prop adapter attached.

Hi caotri just an update i managed to solve the problem with the adapter. Turns out it was not bent rather, the adapter did not sit flat on the motor due to poor machine finish. I promise to post pics of it tomorrow so you would have a better picture of what im saying. But sad to say this is a poorly built motor i suggest you buy those specialized motors from hk, or those rctiger 650kv.

Please, can you be a bit more specific? Looking at the RCTimer's picture of these motors, they look good if nothing else. I know and understand that quality of many items coming from China are in the toilet nowadays, but the cost is still the best I have seen so far.

I take a marker and cover the top of the motor where the adaptor sets over. Hold the adaptor against motor and give it a couple of twists. Most of the time I find the problem is they second sourced the adaptors and the hole in the bottom isn't machined deep enough. If this is the case the twisting motion will rub the marker off top of motor. I haven't tried this one but seen it on several others.
