You need a greater angle on your dihedral and or the polyhedrals and I can't tell if you're detail is set right or not but it should be 100°. Both those things will make a huge difference.
I saw a true master composite layup guy doing sailplane wings once, and he added so many different tape strips/yarn/pinstriping tape to the layup sandwich that seemed to have no effect on the final wing. Most of them were there just to make cleanup and trimming easier! It's a real dark art, and a lot of the art is just about making it faster and easier on yourself with less work afterwards and less waste.
So she’s “Thinking of flight”?……ok, that was bad. Honestly, including your wife’s interest in flight is a great addition to your channel. Keep encouraging April…she’s an inspiration to many.
It was annoying as fuck. I was coming here to see the intricacies of the construction of the plane, not his Asian war bride goofing off in an airplane. The fact that it was mixed in made the whole video trash
3:35 I liked seeing the repair on the crack here, a simple hole to relieve the stresses and stop the crack in its course. Such an appropriate fix for a glider
I'm thrilled to see old school balsa ribs in your preview for the next step. Film covered open balsa structure is hard to beat on the low end of the speed range for a super light airframe. Integrating higher performance structural materials (anything from spruce to carbon fiber) where it can contribute the most (spars!) will allow for larger aircraft. Side note: in my experience, sailplanes dependent on dihedral for roll (no ailerons) a big rudder is necessary to be effective. Really enjoyed the vid and CONGRATS to your wife on taking on the flying bug! I'm eagerly anticipating the next vid.
You need to catch it. Very impressive build. Maybe dial it back 20% so you get the wind penetration up by adding weight. A lighter larger sub 250 glider would be impressive indoors.
One of your best videos so far! April is so natural on cam which is not easy to many. And I bet, especially with your severe health scare, that she really is a supporting star. And yes, thanks soooo much for working on the ePOXy prounouncation. Takes a strong person to change his ways this much;)
Came for the interesting RC exploration, stayed for your wife's awesome adventure into becoming a pilot. That's amazing. High flights and happy landings to you both.
This was a very enjoyable video to watch. The interspersion of the wife's flight segments with the build information made this both informative and entertaining. Nice job editing.
No way! That glider that TF's Wife flew in is the same model as the training gliders at my gliding club in Australia, the ASK-21. I guess they really are widespread!
i noticed at 3:58 that you have metal bars on your window. i think that means you live in california. i hope nobody breaks in and steals your awesome planes :)
Was super looking forward to this video once I saw your teaser photo. Flight duration and range will always be best with fixed-wing, and sailplane-style airframes may be able to improve it further with thermalling capabilities.
amazing work as always... 250g limit is a joke... I've built 80" .52cu glow kadet seniors at about 3.5kg, that is another level of fun... its still legal in my country thankfully
I saw a true master composite layup guy doing sailplane wings once, and he added so many different tape strips/yarn/pinstriping tape to the layup sandwich that seemed to have no effect on the final wing. Most of them were there just to make cleanup and trimming easier!
Hi, could you tell me the elecronics parts names (motor, prop, ESC, RX) of this 250g glider? I like this glider I would like to konw that how you can take off that small prop. Thank you!
Great video. I probably will follow your fiberglass techniques. 😅 Really nice to include your whole family! The wing balance stripes were done so tastefully I thought they were cosmetic 😁
Congratulations for the great work! Please, Could you tell me where to find information on the web about the polystyrene cutting cnc that I can glimpse at 2:01 minutes of your video. Thank you very much!
No difference per the FAA. Same rules apply. If you fly informally, you'll probably not be bothered. If you fly with an AMA club you'll need to meet all the new rules.
THX for pursuing the sub-250 idea!!! It had been on my mind ever since that new drone rule came up. 👍 for more attempts - will be even more so a definite follower!
what if you add acetone to the foam after u sandwich bag it ,my point is that the acetone will eat the foam and you will be left with a fiberglass shell that should be strong ,but light.
This is fantastic! If you revisit this again, let me know how I can help you out. We got our laser up and running too. What was your wingspan in the end? Awesome to watch April get some experience with various aircraft. Cool she wants to be a pilot!
So there we have it, a plane lacking an onboard system for battery voltage is more dangerous than a plane over 250g with voltage display that can be safely brought home without crashing into something or someone.
With every gram counting I wonder if you could have had more wiggle room using a carbon fiber layup instead of fiberglass. I wonder too about the extra effort to mold the wings as hollow carbon fiber shells + spars and omitting the foam core.
Very impressed with your 2m+ build of a 249g automous winged drone. Not only does it have smarts to self navigate, you managed to reenforce the wings, etc. with fibreglass. Had expected to be just bare foam, or foam wrapped in a heat-shrink film. When saw the teaser photo, had thought this to be a pitcheron design with servos mounted near CG. Thought I was doing good building a 1.2m wing this past summer that was ~230g. I bow to you, clearly have a super power when it comes to designing/building unique RC models. BTW: Regarding April's flying interests, I'd highly recommend starting with learning to fly in a sailplane. It's the purest form of flight. Besides for most more complex aircraft when it comes to learning to pilot, it seems 80% of learning involves what to do when the engine, or something related to the engine quits working as expected. This not an issue with a sailplane. ;)
I really like your storytelling style of editing with the 2 storylines interlaced and different perspectives of the same scenes, good stuff! Subscribed.
Very nicely done. If I could ask to use your experience if you were to build a power kite based on a tethered glider what wing airfoil would you use? How would you build it to maximise lift and have the strength to pull the tether out to run the generator?
Leave the heavy motor and drive battery out and rubber launch it. Add a few solar cells to the wing surface. Use the autonomous thermalling software. Would be very interesting to see how far that setup could go. Maybe ESP32 power it, mostly in sleep mode, and only use servos very very lightly.
Nice video. Our idea of 'stiff enough' is clearly different lol. But then again, I'm a member of the BHPFC, so anything that doesn't break at cruise conditions is fine for me. Anyway, you can definitely shed some weight from the wing spar, leave out the fiberglass, and lighten the tail a bit. That does mean you can only fly in super calm conditions and it won't survive any landing harder than a perfect one, but you can do it if you want to. What airfoil did you use? I suppose an AG...? Pretty good airfoils, if you expose the foam it might transition a bit earlier, causing slightly less drag. Edit: Glad your wife enjoyed the flights. I had a day of glider flying for my birthday two years ago. It was way too hot that day - in the cockpit it felt like 45 + °C. So yes, I got sick. I don't think I would have been sick if it was cooler. Also, on my very first flight, the winch cable broke, so that was funny.
Hello Think Flight, amazing video as always! One quick question, what kind of hardware do you use for the autopilot? They must be very small to fit in that fuselage. I want to build light weight autonomous airplane, so I'd appreciate if you could tell me what you used. If you have already showed them on another video, would you tell me which one?
In this case I used an MRO Control Zero, but this could easily be done with any of the 20x20 5g autopilots available by companies like Matek, Diatone etc.
Seemed like there was potential for lightening holes throughout the wing, to shave more weight, but not sure how it'd be done pre-vacuum bagging. Also makes me ponder whether my young childhood days of balsa and doped paper gliders would be lighter for same given size.
Reminds me of an 80" flying wing I built using an HS522 foil. It used 2s indoor gear for propulsion. Didn't quite have enough twist in the wing but thermaled fantasticly. Initial cg test flights didn't go well, lol. It was probably 15 years ago but it weighed way less than your typical Gentle Lady. I still have it but haven't flown it in a while.
Great to see April's increasing interest in becoming a pilot. The future of R/C is 250grams, thanks for exploring the envelope of what is possible which in the oppressive restriction.
I would love to see something like this with some sort of solar. maybe a little smaller wing span to accommodate panel weight and some camera tech. We've had 3 people in the last year (elderly and children) go missing in our small town. They had all been found, but during the search something like this would have been great to have. canvas large areas with a camera and maybe a thermal camera to get potential pings or at least rule out areas of search.
You know, if you embed the carbon fiber strips vertically, they will add meaningful strength to your wings. Possibly enough to forgo fiberglass for packing tape covering?
I'd quite like to know what that type of CNC wing cutter is called. I've never seen the motion system for a CNC foam cutter that suspends the bow from towers before. I've made a few 4 axis CNC foam cutters in my time but that one is rather intriguing.
Try an aerogel foam wing molded in place around a single carbon-fiber spar tube while inside an ultra-thin carbon-fiber sheeting present in the shape of the airfoil.
With a drone that only weighs 250g, it should be pretty easy to bring it down via parachute. Especially since the comparatively huge wing area could probably act as enough of a parachute for a safe landing, as long as you "give them enough encouragement" to stay perfectly flat. I'm thinking about a small "pilot parachute" that attaches at 3 or 4 points. Sadly even the little bit of extra weight would make your wing span less competitive for the record length you are going for. But maybe it would also be possible to fold the tail up by 90°...
Why a engine of a drone which has been crashed to a wall, buged the motherboard of the drone to put this one the problematic arm one of 4 actually can't stop spinning immediately after i plug in the battery ?! What part of the motherboard should be ? @thinkflight ?
Semi-hollowing out the wing cores, using a d-box spar instead of strips on top and under, drilling lightening holes in the outer wing panels and pulling out as much epoxy as possible before bagging the wing should do the trick on extending the wingspan further. And as you say, for a v-tail and no ailerons you need more dihedral. Looking forward to see version 2! Also, why not a pure wing as you'd get way with the same amount of servos (2) but gain a bit more in overall rigidity from dropping the boom and pod? Too thick and heavy compared to high aspect wing?
Recently heard some great things about Depron foam -- rigid (needs little carbon fiber reinforcement), and lighter than EPP -- but I don't know how it'd hold up to vacuum bag building techniques.

You should've went with a flying wing design.
I saw a true master composite layup guy doing sailplane wings once, and he added so many different tape strips/yarn/pinstriping tape to the layup sandwich that seemed to have no effect on the final wing. Most of them were there just to make cleanup and trimming easier!
It's a real dark art, and a lot of the art is just about making it faster and easier on yourself with less work afterwards and less waste.
I would love to see a beginner series on a fiberglass and foam plane by you. You make it look easy but it is a pretty deep set of skills.
This!!!!
And keep that intermingled crap about his wife out of it
They sounded like a high school couple.
Why would he include that?@@nic9172

@2:09 "Smoking betty" please share in your next video how it works. I see 4 stepper motors guiding the bow. very cool!
Good format and build.
And great seeing you and your wife so happy.

i noticed at 3:58 that you have metal bars on your window. i think that means you live in california. i hope nobody breaks in and steals your awesome planes :)
I used 4 of those same batteries in my electric quad I made last year - works amazing and get around a 70km range.
Was super looking forward to this video once I saw your teaser photo. Flight duration and range will always be best with fixed-wing, and sailplane-style airframes may be able to improve it further with thermalling capabilities.
This guy: quietly forms 1gm drone from aerogel, lands on the ISS
Really nice-looking build and even with its aero shortcomings, you did a decent job on the aerodynamics. The bottom line is, you did it. Congrats.

If you do it enough it definitely pays to spend the time doing it cleaner.

This is such an amazing channel.... I'm hooked!
Your in-flight video from the other drone is just awe inspiring, as usual.
can you make a wing from just the mylar filled with air? like remove the foam after the covering has hardened, maybe some internal spars..
What’s the difference in RC planes and drones? Because I have never heard of a weight limit or needing to register RC planes?
Technically you’re breaking the law if your plane is over 250g but it’s not really enforced
No difference per the FAA. Same rules apply. If you fly informally, you'll probably not be bothered. If you fly with an AMA club you'll need to meet all the new rules.
1. cut holes in foam to lighten. 2. Use lighter fibreglass at wing tips, heavier inboard.
THX for pursuing the sub-250 idea!!! It had been on my mind ever since that new drone rule came up. 👍 for more attempts - will be even more so a definite follower!
I'm also about to build a CNC hotwire cutter; cutting the parts by hand is rather difficult. Great video!

I love everyone of your videos im learning so much while enjoying myself
what if you add acetone to the foam after u sandwich bag it ,my point is that the acetone will eat the foam and you will be left with a fiberglass shell that should be strong ,but light.

What material do you use and where do you buy it? Have you DIY your cutting machine or also bought? Thanks

If you add a 3x1 millimeter carbon fiber spar and put it on edge the wing will not Bend at all. I did that with to UMX radian wings 45.5 inch wingspan
Are there plans for that CNC foam cutter somewhere?

If there’s “Crop Circles” in the desert, are they still called crop circles?
nope, out there they are called OHV tracks
April is great ! Thanks.

AG08 for this one. Probably could have gone thinner, the wing was plenty stiff.
for the next iteration you should try a Prandtl wing design (NASA Prandtl-D, for example), which would eliminate the need for a tail surface.
Nice! Yep, more dihedral needed for rudder/elevator only.
This makes a good point. The restriction is weight, not size.
Hello Think Flight, amazing video as always! One quick question, what kind of hardware do you use for the autopilot? They must be very small to fit in that fuselage. I want to build light weight autonomous airplane, so I'd appreciate if you could tell me what you used. If you have already showed them on another video, would you tell me which one?
In this case I used an MRO Control Zero, but this could easily be done with any of the 20x20 5g autopilots available by companies like Matek, Diatone etc.
Say I bought a cheap normal plane and converted everything to run off of servos. Would I be able to fly and actual plane if it was radio controlled?
Seemed like there was potential for lightening holes throughout the wing, to shave more weight, but not sure how it'd be done pre-vacuum bagging.
Also makes me ponder whether my young childhood days of balsa and doped paper gliders would be lighter for same given size.
Stellar content! I would love to see more details on the hardware and autopilot setup. Did you make that CNC hotwire yourself?
Yes, I was interested in “smoking Betty” too. Looks like a double ended Maslow cnc. More info please!?
Thank you so much for what you guys do! You inspire a lot of people
Reminds me of an 80" flying wing I built using an HS522 foil. It used 2s indoor gear for propulsion. Didn't quite have enough twist in the wing but thermaled fantasticly. Initial cg test flights didn't go well, lol. It was probably 15 years ago but it weighed way less than your typical Gentle Lady. I still have it but haven't flown it in a while.
Do you have a video on the foam cutter you use
I think in the uk the limit is 20KG and must be lower than 400 ft and fly no further than 500m form the operator

The 90' solution like they use in free flight is a great zero extra weight option.

congrats on the growth! :3
Can anyone recommend video tutorial to making this equipment to cut foam?
wich airfoil did you used ? And what are dimensions of the plane ? Can you share something about it?
250g including helium? Or after it’s added?
After hahaha caught me!
