Put one in a small Foamy (Graupner Nemesis, 350 grams). With a HK 6x4 Prop and 3s-Lipo 800 mAh, I got really good performance, although no unlimited vertical.

Then I bought two more of these motors - both show breaks in the winding out of the box - no good.

Habe 2 Stueck geordert und erhalten. Sind fuer einen 2-motorigen Flieger gedacht. Leider macht einer der beiden etwa 10% weniger Touren. Werde ich mit dem Ruder ausgleichen muessen. Ansonsten bin ich mit der Leistung zufrieden. Aber HK sollte das Anschleifen der Achsen sein lassen. Ist bei diesen kleinen Motoren nicht notwendig und man kann keinen Spannkonus verwenden.

Original folding propeller of the Hobbico FlyZone Ventura (6x3) fits perfectly, and you may use the old screws.

5.7 Amps with 2S 1000mAh Lipo (idProduct=6472, too thin to insert two!) and 6x3 folding propeler (idProduct=5273), replacing the original Hobbico FlyZone Ventura 380 brushed (of course, brushless ESC is needed).

I'm pending to fly and also to try the original folding propelers over this motor.

excellent, I will recomend this motor for easy star, phoenix, and other similar planes. Thanks hobby city!

Putone in my Easy Fun with a 6" prop and it works better than new. Plenty of power with only nominal drain on battery and low amp draw. Will be buying more.
