great with a skylinerI got one of these not really knowing what to expect ,put it on my new test rig tonight ,can only measure thrust untill meeters get here but on the bench i got 12 oz with GWS supplied assembly with this motor .GWS 10-4.7 prop and 3S li batt i got 28 oz thrust Motor ESC and batt are running about 135deg F after45sec WOT static test WOW!!This is a great motor, lots of power. I put it on a simple stick with a 15amp esp and a 10x4.7 and it flies with real authority.Fit and finish is better then some cheap motors, but the accessories on this one are not great, and had to do some grinding to get the supplied prop adapter to screw on. The rest of the motor appears fine so far, but still working on this one. For the price it looks pretty good so far. Seems so small for the claimed performance. I'm keeping my fingers crossed as testing continues.bought two put them on a twin project and they are more than it needsI pull it on my sailplane . it flys like a rocket! I use 10*8 prop and it give me 7000rpm at 19amp!
