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.

I 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).



Test results:

parameters

kV = 753 rpm/V

Ri = 0.55 Ohm

Io = 0.56 Ohm



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. Empfehlenswert
