This is a new Hyperion HS4020-910 Motor that was designed for use in a large Helicopter, something with around 500mm blades.
As the pictures show it has a long protruding shaft up front, and also is to be "back mounted" which could be a problem if it was used in a plane.

The specs are as follows: KV is 910, can operate from 8 cells, continuous amp draw is 65 amps, continuous wattage is 1820, maximum current is 87 amps, maximum watts is 2455, weight is 284 grams (10 ounces), shaft is 5mm.

Xmas price is $50.00

Ivan, I need to know what amperage you want to draw.....and how heavy is the item it's going into. Like do you need 300 watts or 600watts.

Thanks Bill. Most likely next weekend due to covid restrictions. But I'm desperate for that exact motor

Ok Ivan, 40 amps on 4S will give you around 600 watts and on 3S about 470 watts. That should be good for a 3.5 to 4 lb plane so now I have something to go on. I'll have a look and get back to you.
