This motor installed on my Omega 1.8. Its a 600 gram with a 9x5 graupner folding prop and a 650mh lipo. This set up work excellent.Motor itself appears to be good. THe included prop adapters are not exactly straight. Took some work to get them straightened.
4 cell 2100 HXT pack, with an Align 25a ESC at medium timing
3 blade 9x7 Master Airscrew prop
12 amps to start, dropped & settled out at 11.4 amps under load.
Work nicely on my 2.5 Omega polyI tested one specimen. It has higher internal resistance and lower current limit, but it is still performs well on small acrobat with 400g AUW with 3s1000 and APC E 10x4.7 propeller (takes 7A), it has high thrust to current ratio (77g/A).

10x4.7 is best and maximum for this motor, with 11x4.7 it gets very hot quickly.

I am giving four stars because motor didn't fully meet expectation based on specification. But I still recommend this motor and will buy again if I have smaller plane which needs bigger slowly rotating propeller.
Sehr guter Motor. Fliege ihn an einer 10x4.7 sf apc. Der Versand dauerte 8 Tage in die Schweiz. Zubehr ist in Ordnung. EmpfehlenswertSehr guter Motor. Fliege ihn an einer 10x4.7 sf apc.
