Is this the "Draco" in question?
So it sounds to me that he wants to spend some of his earned income on a plane that really is one of the few viable means of transportation in the boonies where he is king. It's commendable. Perhaps he wants to fly higher (the article seems to imply that) so if some snafu happens again in mid-air he has more time to glide his plane and land safely. Is that a wrong goal to pursue in a high-altitude place?
According to the article, the project is "only" 1 $million!
Did he bomb some place to get rich contracts for someone?
Did he invent yet another "social media platform" for teens and tweens to admire each other on?
Did he jack up the price of epi-pen to make a killing?
Or did he engage in "financial innovation"?
No he assumed personal risk and built something ... most of the world can agree that it is admirable ...
Back to "electrical plane", informed opinion (not mine certainly) thinks there will be no such thing in the near future ... not with current battery technology ... unless we can have big charged coils of metal floating in the sky that as you fly through them (guided by GPS), you induct-charge some super-capacitor ... or when some other novel "anti-gravity" physics become mainstream ...
As for noise, didn't they ban the old Concord from NYC because of "community complaint"? Surely there are (armed-to-the-teeth) neighborhood associations in back-country Utah that can and will lodge displeasure if the decibels are too outta line.
I might come across a little cranky myself ... being on-call has that effect. I apologize in advance. This forum is an enjoyable place to visit.
Yeah, that's it. I learned a few details in reading the article you posted, this project took him 5 months, that is absolutely unbelievable! No matter how much money you have to throw at it, there are just so many details that suck time, like finding you need something real bad, sent UPS, and it's the start of a 3 day weekend (my personal unfavorite). Like him or hate him, the guy is some sort of frigging genius, and a hands on mechanical one at that.
The altitude it can fly at is mentioned as that's where it's fastest (thinner air) and the engine most efficient.
I too have witnessed a B-1 full afterburner takeoff, and really enjoyed the incredible noise, totally awesome, but I bet when it flies low over cattle they drop dead, my plane, they don't even look up!
I've said it before, but what I can see happening, sooner then pure electric craft with a decent range, is a hybrid. I want my PlugIn Prius's powerplant in my plane, (Draco's owner could do this, probably in less then 5 months, I can't) how cool would it be to make a long descent and be topping off the battery, to assist in the takeoff? OR (and this is really out there) tied down overnight on the ramp, in windy conditions, and be trickle charging the battery by a windmilling prop? Not practical, just a fun thought, like people thinking we recharge our bike battery while pedaling.....
The Prius uses 1.5 GPH at 75 mph, more or less, about half what my plane uses at the same speed roughly. The huge difference is the plane travels in a straight line, and in mountainous terrain that can effectively double the planes advantage. Just yesterday, fighting a strong headwind, the GPS was telling me I was making 55 mph over the ground, while the airspeed indicator was showing 83, so I was getting passed by cars below. But then the highway got twisty, and I was able to catch up, and thought I had the last laugh. Then the wind got stronger, and I hit a bit of rain, and it got a bit bumpy, and the laughter stopped for a bit. Gusts to 37 MPH as luck would have it, right on my nose, in a low drag car like the Prius, no biggie, planes and flying are great, until they aren't.
