Mark Beierle, the designer of the Earthstar line of planes (Thundergull, Gull 2000, Odyssey), makes exactly that point. Ultralights and near-ultralights tend to be flown a lot more by seat-of-the-pant ...

I have been using Avare on my Samsung Galaxy S 8.4. Works great, and free updates! Two features I like are the extended runway vectors after you tell Avare which airport you target, and the airport la ...

It is hard to tell from the photo, but the glare shield does extend about 3" back over the panel.

Even at full brightness, the tablet cannot touch the brightness of the GRT EFIS next to it. I ...

Here is a photo of the panel in my just completed Earthstar eGull (electric powered). Not a Firestar, but might still offer some ideas.The 8.4" Samsung tablet in the center will normally show a m ...

I have seen several specs for instruments that use pitot pressure saying that one pitot for several instruments is OK. Makes sense when you realize that a pitot system does not actually move air, but ...

I edit my photos with a free program called Irfanview (PC. Apple products probably come with better tools). If your native viewer does not support resizing, Irfanview is a powerful, yet easy to use al ...

Tone generator? Now we're talking (ha!). I can easily see how to make a sensor by adding a second pitot tube at 45deg or so from the standard one, but I would want an audible warning, even more th ...

Since we're off-topic anyway, here is my suggestion: use a free-ware app to resize. Today's cameras produce very high res / large files, so resizing is almost always required before posting. I ...

Split-point bits work great. I bought a 10-pack #30s and made it through my entire project (Earthstar eGull).

I am building an Earthstar eGull, just lurking here. Mark Beierle solved the "chafing cable" issue by placing a "comb" on the forward face of the boom, UHMW or teflon, 1/8" th ...

I think what Dany is trying to say is, can I convert the aircraft from tricycle gear to tailwheel (like the one in the photo).

"When will purchase the aircraft I will send you pictures.
Ho ...

Mark, I cannot help you with quantities, but I just covered the wing and tail feathers of my Earthstar eGull with Oratex. Easy, odor-free, non-toxic, and I saved a bunch of weight (no paint!). I found ...

I decided to build an Earthstar eGull 2000, but am still lurking on this interesting forum. The purchase agreement with Mark Beierle includes 2 hours of transition training in his Odyssey, as well as ...

From empty, 10 hours on a single 15A 110V AC outlet. Or half that if you have two circuits and 2 chargers. Or less if you have a 240V outlet. Or 45 minutes on a CHAdeMo outlet...

Battery, motor, ...

Hello Kolb flyers,
since Chris brought it up: I have been mostly lurking and almost went for a Kolbra, but I have recently begun building an Earthstar eGull. As much is I liked the folding wings and ...

Thanks for the tip, Charlie. Most of us will have ATF fluid around (even used should work), but I wonder if fingernail polish remover could sub for acetone?

As an alternative to the Challenger, you might also consider the Excalibur - reportedly the better flying plane. I looked at a kit under construction and liked it: adequate room in both seats, dual co ...

Beautiful, Larry! Video worked well, excellent quality. And the soundtrack made it even more enjoyable.

Inhospitable terrain, alright. Do you fly with a ballistic chute? How many seconds would you ...

The NSI EA81 is a Subaru conversion. I think Stratus 2000 is the only major Subaru converter left. Right power range, but heavy. The larger VW conversion with belt reduction from Great Plains should m ...

Thanks, Richard - I had no idea this is regulated to this degree. I'm not sure if this particular airport receives federal funding, but it does not look like that would be a necessary requirement. ...
