Brushless motors will spin in either direction, all depends on which way you plug in the 3 wires to the ESC.

The CW and CCW usually determine thread direction, but they do not have to be that way. You can use all CW or all CCW if you want to and wire accordingly like Jackson stated.

Good lord that is a huge motor. It is strange that it doesn't tell you which way the thread is going on the prop adapter, maybe at checkout they will let you choose? I'm not sure I don't deal much with hobby king, but I know they usually advertise them as CW or CCW, depending on which hardware is included. Maybe enterm all the info into the search bar and see if you can find a listing that is more specific. Each warehouse will have it's own listing if you actually search for the item.

Funny, I was going to ask the same question. I've read somewhere that you shouldn't run them in reverse. If there was no difference and you just wire them according to which direction you want them to go, what's the point of having CW and CCW threads? The only possible explanation I can think of is that if you have a motor rotating CW with CCW threads, there's no way the nut can spin off. I'd like to hear more on this.

That is exactly the point, maybe I should have mentioned that. They are self tightening prop nuts

Hi the CW and CCW is the prop mounts on top so the props dont spin off ,the motors are all the same

Thank you! That explains a lot. So if I'll buy x4 these motors, I could run them CWx2 and CCW x2? Or I have to buy something to do that?

No, there is no positive and negative on brushless motors. If it's not going in the direction you want just switch anytwo of the three wires

Hi mate so you under stand this a little better , A brushless motor is 3 phase this is why you have 3 wires from the ESC .
The ESC does a few things it converts phase-less DC from the battery ( lipo) into 3 phase AC it will spin the motor by pulsing the AC current ( timing ( Degs) and Drive Frequency this in HZ ), this is why if you change any 2 wires the motor, it will turn the other way as the pulsing goes the other way round the windings , this is the simple way to understand what is going on ,and while we are talking motors the KV is the amount of RPM per 1 Volt you put in some guys will run a 3 cell motor on a 4 cell battery so its faster and more powerful but this can make them run hot and burn out ,some motors will list 3 to 4 cell so if you go for the 4 cell set up they normally run a smaller prop but you need to make sure the ESC will work on 4 cells

Thank you! Then I'll order 4 of these motors right away with 1245 props :).

here is a little info that might help you better understand it


DC current is determined meaning that it is steady, a strait line, so there is no phase.



Here are a couple graphs I did really quick that should clear any of that up.

AC in your house: (single phase AC, it is called that because you only have one wire that is 'phased')

Note that voltage is defined as the energy difference between two points so when you have -120v on the 'hot' wire and 0 on your neutral you still have 120 volts worth of energy.







12v DC: (no Phase)

Here is a little animation to show a 3 phase brushless motor like we use.

Hope this helps, if you have any questions about it feel free to ask.

Yeah, this info helped a lot and that motor gifis awesone. Thanks.

Overall this thread was really helpful. Awesome forum!

Speaking of motors, my LHS just got some Emax RS2205 redbottoms in. $48.......................EACH! Think I'll hold off for a bit
