I use the simprop acro 280bb from hobby lobby:

Use an 8-9 tooth pinion with this motor, those cells and stock blades. Use the stock 10 tooth with hrnet carbon fiber blades.

Ball bearing supported and replaceable brushes. Many flights on mine with zero problems and the motoro still looks fantastic.

Others have had good luck with an Orion motor and others with a speed 300.

Good luck and let us know how it goes!

Seconding what Steve says. I've been using an Acro 280BB in mine now for quite some time and it works great!

Steve, I've been using the stock 10 tooth and the stock blades. Should I upgrade to some CF blades? If I do, what will this do for me? (besides look really cool)

Josh,

If you tend to break blades like I was - the CF ones will take a real beating! I am not afraid of breaking a blade not that I see how much of a beating they will take. I think this has helped me to move into forward flight on this little bird.

You also get a higher rotor speed which makes for a more stable hover. They are very well balanced so no shake. You also get less pitch up when in forward flight. I honestly believe the tail motor runs cooler.

Steve

PS - oh yeah - they also look cool

Very soon GWS will have a new motor for this replacement.

GWS EDF64-100, the duct fan motor is a special tunned up 280 motor. We tested many samples, and worked great!

That is what I have been hearing. I would think a high frequency ESC would be in order for a coreless motor, but those who are using them report good results. I have no personal experience with that motor.
