Earthstar Electric Gull 2000 at Arlington 2011

Really cool video!

Here are some tech comments from the designer and developer of the eGull motor; thats me.

Kelly Controller calls it the 500 A type, because it can deliver 500 A peak for one minute. But the continous current is only 250 A. So the controller is not too big; it is just right with some headroom for a little bit more power. The power consumption is mainly given by the propeller diameter and pitch.

For more information about the motor search for "Forschungsbuero".

Thank you, Zach. really nice video, wish there was like surround sound to make out the whispers over the t-rexs. that u turn was neat, almost like a rotation. did Mark pull off an impossible 360 too at arlington, engine switched off, <500ft, <2mins?

@rahulchou Thanks for watching! And no, he didn't.

Wait so 18 or 20 amp speed controller?

[chosen1007R]

@chosen1007R You idiot it says 250 amps.

[creekriot]

Are there many of these (or very similar) in use? I believe I saw one in the air north of Canyon, Texas at about 1:30 PM on 7/10/11.

@creekriot thanks for watching. And no, not that I know of, but im sure there are other electric planes around, if that's what you mean.

@RedDevilSquadron Thank YOU for the great video. What an INCREDIBLE airplane! I was driving when I saw one that was similar and first thought that it was an ultralight. About the time I realized that it was too large for an ultralight, I noticed that there was no fuselage between the cabin and tail. I found myself doubting what I thought I had seen.

How many Amps is it pulling on a cruise speed?

& Total Lipo Capacity?

[RedDevilSquadron]

About 250 amps. The ESC is a prototype 500amp, so its much bigger than necessary. And not sure on the total capacity. Thanks for watching

Hey Zach...thanks for posting this! I saw this at the fly-in and was very curious about it. I think an electric ultralight is awesome. Sounds like a T-Rex 700E :-)
