It's easy to improve the internal cooling my modification of the three spokes. Simply abrade to bring them into a "propeller-like" shape.

I have multiple planes with this motor. The FC28-12 brushless motor is comparable to the BP-21 in performance. Perfect size with a sport 7X6 prop at 17A to carry a 15 oz plane at 70 MPH.
I like the motor but have had trouble with what I thought originally was bearings on three motors but ended up being debris on the magnets. This debris looked like fragments of a broken magnet but all of the magnets in the motors were intact. All of the motors came on the same order.
It's a little difficult to clean magnet fragments off of the magnets. The E clip was easy to remove and it was easy to remove the shaft. I used a dry cloth, toothbrush and air compressor and finally got the magnets clean and saw a drastic improvement in motor performance.
I will buy more of these motors but if they grind at all I will check the magnets and bearings.

| I love theese babys. Low cost and enough power for my 350g Delta with 3s HC Rhino 1250mAh and APC e 7x6. That´s enough for vertical climb. 5 Stars!!

| Amazing power to weight on my stock stryker 134kph 7x6 apc style prop 30amp esc 2200mah 20c approx 15min flite time full power all the way battery get warm motor stays cool only down side as pusher setup puts load on the small bearing tends to not last long but for the money just buy some more for spares easy to mount on brushless mount put motor on outside and if you got a spare motor put removeable mounting plate on in side of mount and bolt together you wont be dissapointed good cheap setup

Good, cheap motor used on my Easystar with a 6 x 4 APC prop, climb and glide lets you fly for over 40 minutes. I have another on my Gonzales 30 inch wingspan sport using a 6 x 4 folder, 3 cell 2200 lipo giving over 15 minutes flight.
Ample power for the job.
The only fault are the bearings which last for about 10 flying hours. But at this price who cares!

Tested on 2S l600mah lipo with 8x3.8 SF
prop. Pulls just under 10amp. Good idea
to have bit of airflow over motor. Runs
smooth no problems! Great value.

Excellent motor for the price. Have been running it with a Bluebird 8x6 and GWS 8x6 on 3S 1700mAH lipo. Very good but not unlimited vertical on a GWS E-Starter. Have not had any problems with the bearings and I have been running it for about a year now.

Great motor. Slap an 8x6 on this guy and WOW. My 20oz cessna 182 RTF from hobbycity now keeps up with single, small EDF planes. Even outruns a few at the park. That being said,
Mine also had magnet fragments in the housing and I had to take a high pressured air hose and blast them out. Took a while. Only reason why it's 4 stars instead of 5.

| This is one of my favourite motors for my scratch build projects. I have several and not one has failed me. It is very versatile, and I have one or 2 motors on my shelf just in case I stumble over a new model to build. Recommend this motor.

| seriosly guys, you cannot beat this motor! if you want to upgrade your easystar (easy star)!!! all you do is hammer out the stock motor insides, glue it in place, (make sure you get rid of the magnets) then glue some ply in the end of the can motor, and screw the brushless to the motor with self tappers, and use a tower pro 30 a speedy, glue it on the top of the wing holder, run the wires into the fuse, and use a 3cell 2200mah, near verticle 500*

| These are very good motors. I use them on all of my parkjet builds. Thay work great on planes up to 20oz. With a 7x6 prop and a 1000ma zippy lipo you get all the power you need and still have 8-10 min flight times.

| I plan on purchasing more of these motors. They have perfect power for the park fliers I am building. You can't go wrong with this motor. Be sure to use the appropriate prop size or you will not get the full potential out of this motor.
