Default Brushless motors of varying power?

My question is for those with the HH Brushless upgrade... I have done several of the upgrades and fly my CPXs all of the time. I have seen some of the motors with insane head speed and some of the motors with a much lower head speed.

It was making me wonder if perhaps the motor was showing signs of wear or if some motors are just that much better than some. I can say with 100% certainty its strictly variances with the motors because the batteries are all fresh and I have done swaps in the same helicopters in the past.

Anyone seen the same?

Lots of things will change the speed of a motor, Regulating the voltage, regulating the frequency, number of poles / windings. But there is only 1 way that a motor will slow down due to age. And that is bad bearings. You should be able to hear or feel that.

Well I did the easiest test I could think of. I swapped the motor I suspected of being worn into the CPX which had a super fast brushless motor.

The test confirmed it is the motor that must be worn. Looks like I may have to pick up a spare to keep on hand. I do fly the heck out of the little CPX motors so I guess it was only a matter of time until one wore out a bit.

Once the HH motor bearings wear out, I would recommend replacing the motor with a BL outrunner and use that with the original HH esc. The esc works very well on other motors. That is what I did and have never looked back. Tons of power with no motor boggs. Keep in mind you do need to swap out the frame to do this. There are cheap 3d printed options that work well.

I agree 100% and I actually have several brushless outrunners in my Nano collection - all of which use the stock HH ESC with no issues.


The HH brushless inrunner motors seem to have noticeable variances when they are new which was what sparked my post. Some of them are just flat out monsters and others are just "good."

So I found out something after tinkering with the Nano’s the last few days. Rather than go into detail about every part which I changed thinking something was maybe bogging down the brushless motor (I basically rebuilt it to brand new) I ended up deciding to change the one thing I didn’t bother to change - the brushless ESC. I tossed in a new one and BAM! Thing was flying like a monster. I am baffled as to why the brushless ESC works but was causing the motor to be sluggish. Perhaps a failing FET? I’m used to the ESC’s just burning out but I’ve never thought about it “wearing out.”
