Building what you want can never be useless. You are learning and kind of teaching. It is woth it.

I think the simplest improvement you could do is reduce drag, there's a bunch of little places, around bolts, your rudder pedals and boots, various connection points for things, etc, where I think little 3D printed more aerodynamic caps and things like that could be implemented to reduce drag. Every little thing counts when it comes to drag like this and you probably could help your battery life a decent bit with simply reducing as much drag as possible.

If full scale is anything like models, an aircraft with lots of dihedral will pitch down with a pure rudder input, in addition to banking. It's actually a good way to avoid a stall.

Do you think end caps on a wing with that much dihedral would be beneficial? If you could reduce the turbulence at the wingtips possibly you could get more flight time.

Unless you are pretty much on surface of the sun there is no point doing that. You need the panels, those will increase weight and drag, nor wont be optimally angled to light. Then you need charger that also increases weight further. in the end you have increased weight so much that if motor is powerful enough to carry all that extra shit, you create about same amount electricity as it takes to carry extra weight. Only plus side would be potentially over time charging the damn thing if there is no power outlet around, but since range of this thing is so little already you can just land and plug it into wall charger...least long as the batteries are still alive, witch is maybe 10 years on high quality ones, before you need to replace them or just go up run out of battery in seconds and come back down. Note as airmanship you should always have extra fuel, if you need to go around or divert to other field. In this case you need extra capacity and since your life is essentially on the line of cheapest possibly made semiconductor actually working, i would highly suggest using two engine design with separate controllers, so you have back up system if main engine, battery or controller fails.. same with controls.

Solar panels won't make much difference. Let's say you are flying an aircraft with 13 square meters of wing area at noon, on a perfectly clear day, when the sun is straight ovehead. Insolation might be about 500 Watts per square meter. If I'm not mistaken, that's about 6,500 Watts. You've installed very high grade, super duper solar panels which are 30 percent efficient. That takes you down to 1950 Watts. You've used a truly excellent motor that is 90 percent efficent, taking you down to 1,755 Watts (2.4 hp) or about the output of a hand pushed lawnmower that's badly out of tune. If you have a wonderful, large prop, spinning slowly, maybe it's 75 percent efficient at making thrust, so we're down to 1.8 hp. Let's say we have an ultralight that weighs only 400 lbs with the pilot, that has an L/D of 10. Both of these numbers are probably a little better than Mr. Sripol's aircraft. Let's say our aircraft gets it's best L/D at 50 feet per second, or about 34 mph. At 10:1, drag is 40 lbs. We have 40 lbs times 50 fps, or 2,000 ft-lbs of THRUST horsepower. That's about 3.6 hp. If we're using the aforementioned prop, we'll need about 4.8 shaft hp from the engine. To climb at a reasonable rate or take off in a reasonable distance, much more power would be required. To make the electric version work, even on a clear day at noon, on an equinox, at the equator, we'll need a Skycrane to hold a gigantic magnifying glass over our ultralight. In the real world, when the sun isn't straight overhead, or it's hazy, performance will be MUCH less, not only because of the less than perfect angle the light hits the solar panels at, but also because it's taken a longer path through the atmosphere, so more has been filtered out.

The scene where it was plane leading a 100 paragliders was epic. Like leading an aerial attack.

As someone learning aerospace engineering it is kind of interesting how we use Bregeuet equations to calculate range and endurance based on the idea that an aircraft loses weight during flight. I was never taught any equations for electric airplanes but it does seem like it would be simpler since mass is constant.

Great video; I’d love to see more of this concept. The tandem in-flight footage is just about breathtaking. The delight of the flyers was evident.

Hey Peter, look at it in this way: you get to build flight time 20 minutes at a time. You also have the satisfaction in getting that time in a bird you built yourself! How cool is that!

Your aircraft are very useful. Each one is a valuable learning experience.

This guy is a legend for me already He made his own homemade plane ❤

Not useless at all! He is becoming a rather fine pilot, and a terrific engineer!

At 8:05 it almost looks like a stall. the right wing falls then recovers.

Peter, it flys great looking at it 👌 I can't help thinking that you might save some drag (and Amp draw at cruise) if you put some simple cowlings around your feet 👍

Be interesting to see flight time if you added batteries over the 254lbs mark
