would someone please mind posting a pic of the motor saver and motor mount?

I've bought and used more than 20 of these motors on various planes. GREAT VALUE! Last 3, however, not so good? Usually run an 8 x 4 prop on 2S. Runs great at first. Then, after a few runs, one of the windings TURNS BLACK and the motor stops working. This has happened on different planes with different ESC and different lipo's. I assume the problem is with the motor? Anybody know what's up?

Hi handyjap, thanks for your guide. I'm really new to rc electric. Please advice how you will choose 2 wires among the 3 wires for connecting to the ESC ?? Thank you very much

The one side of the brushless ESC with 2 wires (one black and one red) connect to the battery. The other side is the output to the motor and has 3 thick wires. There is e third set of 3 thin wires which is the BEC output for the receiver and servos and the control input for the ESC speed. If the motor turn the wrong way round for the propeller (test without the propeller installed aplease), swap any 2 of the 3 wires connections between the motor and the ESC. That means disconnect any 1 wire connection between the motor and the ESC. Then disconnect a second wire connection between the motor and ESC. Now connect the first disconnected wire from the ESC to the secondly disconnected wire from the motor and the secondly disconnected wire from the ESC to the first disconnected wire from the motor. As this is actually a AC 3 phase motor, swapping any 2 wire connections between the motor and supply with each other will reverse the direction of turn of the motor. I use "2mm Gold Connectors 10 pairs (20pc)" PRODUCT ID: AM1002A between the motor and the ESC to be able to easily reverse turn of the motor but for higher current you might consider "PolyMax 3.5mm Gold Connectors 10 PAIRS (20PC)" PRODUCT ID: AM1001A.

Hello, i recently bought this motor and I received also a prop saver ( O ring) and a spare shaft. However, the 3 connecting wires are all black and not coloured as shown in image above. Can anyone tell me if this is normal ???
 handyjap 825 points
Mine also has 3 black wires. It does not mater much as if the motor is connected and run the wrong way round, just switch 2 of the motor wires. Use tape with a marker or colored shrink s***ve to remember the connection order if you have to disconnect.

This is a good motor for smaller props sizes than the 1300kv and 1500kv versions. In my bench testing I got the following numbers:

(With a 3s pack)
APC 5x5: 10.82v, 6.7A, 73.5W, 7.1oz thrust
Gunther 125mmx110mm: 10.73v, 7.08A, 76.4W, 9.4oz thrust
GWS 6x3DD: 10.82v, 5.68A, 62.3W, 12.1oz thrust
GWS 6x5SF: 10.49v, 10.86A (!), 114.2W, 13.1oz thrust
GWS 7x3DD: 10.74v, 6.67A, 72.5W, 14.7oz thrust

(With a 2s pack)
GWS 6x3DD: 7.91v, 3.61A, 28.7W, 7.8oz thrust
GWS 7x3DD: 7.84v, 4.36A, 34.3W, 8.8oz thrust
GWS 7x6SF: 7.35v, 9.5A, 70.6W, 11.9oz thrust
GWS 8x4DD: 7.5v, 7.59A, 57.5W, 13.7oz thrust

There is a good range of performance options for lightweight planes.


Thanks HC!

This motor revs a GWS 8 x 4.3 @ 7000 rpm on 2s480 Tanic cells @ 8 amps. That gives you 300g of thrust.
Its a 12 Pol motor with 16 Magnets.
Weight is 24g. The performance of this motor could be improved by using smaller magnets, there is no gap between the mags. Coverrage of the mags should be under 80pcnt of the ring. The winding is lousy, my grandma can do better. "you get what you pay"

I have 4 of these motors. Need I say more? OK, I will. Great on sub 10oz planes, esp with a 8040HD prop on a 3S as a pusher on my 10oz flat jet. Keep the drag down and don't use more than an 8040HD prop. Even sounds pretty cool. We have 4 of these jets/motors at our field now. Can't go wrong if you use it on light foamie planes.

Looking for a little parkjet motor and ran it up on 3S 1000 mah (Hextronic) got 14000 rpm at 6.7 amps with an APC 5x5. The 5.5 x 4.5 was a bit much for efficiency, the rpm dropped to 13200 and the amps went up to 8.1. With a 6 x 4 the Pentium 12 began to loose sync at 10k rpm. I like the 5x5.
