A lot of people have complained about the stock bearings in these motors, but my biggest problem is that there is too much play in the shaft (the bell moves up and down) in about 75% of the pieces I have. First, can anyone tell me the size of the C clips used to retain the shaft? Second has anyone tried to remove the play in the shaft and if so, how?

I actually replaced the bearings on these motors before I ever used them figuring it would be easier to do them all at once before they failed. I found the retaining clips at Zoro Tools. The part number is G0468955. You get a bag of 100 for $3.14. I just flew my hex for the first time yesterday and they worked great.

I replaced all of the bearings, but the imbalance and play in the shaft makes them a real headache.

Hi, tell me please, what kind of cross plate should I use for this motor? I've tried http://www.hobbyking.com/hobbyking/store/__14501__NT
M_Prop_Drive_35_Series_Accessory_Pack.html but
only 2 holes match Thank you

I have always mounted my motors using only two screws. You do not have to put four screws in, thinking that's how it should be mounted. If you can match up the two 19mm apart holes, you re doing very well. Even the 16mm apart holes would do too. Use blue thread lock, or the motor will come loose unexpectedly. Happy flying.

Does anybody know where I can buy prop nuts or cones for this motor?
 __HaKK 729 points
Hi Mark, I just measured on my motors that you just need M4 lock-nuts with a spacer. If you live in a metric world, any hardware store has the 4mm lock-nuts or "Hex locknuts M4 10pc" (PRODUCT ID: OR017-01006-M4) or other M4 lock-nuts from Hobby King.

BTW, if you look at my RCgroups blog entries, you can see my buddy codes for this motor.

before using, you have to check the motor in the following manner: 1. you have to disassemble, and see if any winding are falling off the teeth. If they do, you should put a drop of glue or something to keep the winding from coming off. 2. not all bearings are lubricated! be aware. you can remove the bearing shield and put some oil inside. I've used a "high speed bearing oil" from HK in the car's section. otherwise the motor is very good for my octo! I'm using it with F-60A ESC (flashed with SimonK firmware) - works great! these motors are very good for the money! will buy more of these... essentially these are as effective as re-winded DT750 - with APC 12x3.8 or 13x6.5, 4S battery this motor pulls 1000g with just around 10A and at approximately 50-60pcnt of the stick. - after about 2 min - it is still cool to touch.

Pretty impressive motor unit. Delivers gobs of power on a HK Turnigy 2200 20-30 Lipo and GemFan Carbon Nylon 11x4.7 Props. Finishing is great, installed it on a Reptile 500V2 frame and flying on a APM2.5 FC. Great value for such a high performance motor.

I have bought several pieces of this motor. I have found some quality issues. 4 of 10 motors was missing the main shaft screw and two motors came with loose bottom bearing. The motor itself is high quality. Just look for missing screws or loose bearing. If you are planning to use over 1.3kg multi rotor and 10" props, use 4s battery, or change for 12" propeller. With a 1.6kg quad/3s/10x4.5 props it hovers in 60-65pcnt. In a hex a/2kg/10x4.5/3s it hovers with a little bit over 55pcnt, but its power hungry (10min with 5000mhA 3s) and is a little bit sluggish. So, in my opinion, 4s is mandatory with 10" propeller and multirotor over 1.3kg, or just try to use 12" props. All tests I did motors came down pretty cool. Highly recommended.
