Why the flying wing has an inverted airfoil ?
@usefulaircraft13 күн бұрын
Honestly, I liked how it looked. I built another plane with the same style wing, and it flew great inverted. So I tried building a plane with the wing inverted, and it flew great, and looked better. The plane flies due to Newton, not Bernoulli. It's all Angle of Attack. There are more efficient wing designs, but this plane is so simple and fast to build, and compared to kits that take hours and hours to build, this is a great trade off. Even if you crash it, you could recycle the parts and be back flying that afternoon. Thanks for your comment. I hope you enjoy.

Nice video, good narration. A hot glue tip I've found that you may find useful: if you've glued a joint and have to undo it, a little isopropyl alcohol will release hot glue, and a heat gun will get it liquid again, I've even used a soldering gun to reheat the glue when it's in a tight tricky spot. A few practice pieces on some scrap board will have you up to speed in no time. Have fun

Great tip. I keep a squeeze bottle with isopropyl alcohol on my workbench, and there's a heat gun under my bench. The alcohol is brilliant, it works amazingly well. The heat gun however takes some skill. If I'm not careful, it can impact the foam and deform things. You've got the right idea. Keep the tips coming! Thanks for your comment.

You need to add some color to that thing I could not see it. I also fly a lot lower and closer to myself. When you fly so far out it makes it harder to keep orientation. Also if you are using a GoPro to film they are horrible for filming planes. A cell phone with a hat mount works so much better to film planes in the air. They look bigger and much crisper on most Cell phone cameras. With that said. That plane is awesome! I would love to build one. It looks fast just sitting on the bench. Great job!

I’ll agree - I’m new to the photography side of this, so I’m learning as I go. Adding to the problem is this particular model is small - really small. It fits on a car seat with room to spare. My larger models are easier to get on video, and to see in general. You’re also right about the splash of color. I usually just use a line of painters tape to mark the underside. It’s cheap and works well. The bulk of my planes are FPV - so many of the above points are moot when you’re looking through the onboard camera, but it seems there’s interest in the sub 250 stuff, so I’m happy to share some of my smaller RC planes.

I would launch that bottle rocket strait up, to avoid a crash at launch. I assume the thrust to weight ratio is about 2 to 1.
@usefulaircraft17 күн бұрын
While it would be easy to put a bigger motor and prop - but this is a very efficient, tiny motor (to easily keep it under 250 grams, and for better endurance) - so it doesn’t have that high thrust to weight ratio. Torque however is still prevalent - so until you get airflow over the wings and stab, the plane is prone to torque roll (roll opposite the direction of the propeller). That said - the plane is slick - so it just keeps accelerating straight and level. For vertical climbs - it’s all energy management - it’s got good penetration, but you’ve got to enter into the maneuver with speed as it will bleed that energy eventually. That said - it’s a really fun plane to fly, as she loves to run, and has great response. I do have other planes I’ve made that have greater than 1:1 Thrust to Weight ratios - and they’re fun too. Just brute force power - but very different flight characteristics. All of them are fun for different reasons. Thanks for your comment.

If you want to up your foamboard wing game there is an old content creator named nerdnic who had some good design ideas, do a search for his speed wing video. He goes through the trouble of shaving the leading edge of the wings then glueing the top and bottom so they come together to a point. Hard to describe. But its super slick. Also, not sure if this meets your weight requirement for a spar but he shows using 1/2" * 1/8" aluminum bars from box stores, they are only a few bucks and you can even put dihedral into them. For fast and heavier planes those spars are great and the weight isnt too bad, sub 250 they might be chonky. But having a chunck of aluminum for a spar to bank and yank with feels bulletproof.
@usefulaircraft18 күн бұрын
I browsed some of nerdnic’s builds as you suggested. He’s a craftsman - and his builds reflect that. His spitfire is really cool. That said, I’m not trying to make my planes to look like anyone else’s - I’m more evolving a design to suit the purpose of the build. Furthermore, I really draw from simple, quick build planes. My designs are made so I can pack them small, and carry them with me and build them quickly in a hotel room to stay entertained on work trips. I’m just going in a different direction. It wasn’t always this way -I’ve built up full wings from hand cut rib and glued them onto spars pinned to plans. Iron on covering, and days and days spent building. Life got complicated, kids, work, and my free time diminished, so I came up with simple planes that I could build the night before I went to fly. The style has evolved, and the number of unique parts I’ve always tried to reduce. While I’m not opposed to 3d printing parts, I try to avoid metal, and other materials (I did use CF tubes and strips for a while - but wasn’t in love with CF as I don’t have the tools and safety stuff to mill, grind, cut or make CF layups - as I don’t find the risk/reward worth it for me) - and that’s simply a choice. 3d printed spars turned into popsicle sticks as an experiment - but they’ve worked remarkably well, and they’re cheap - so I’ve used them more often. Interestingly - I used to use separate sheets to build the wings, and I even tried trimming the leading edges to profile them… but then I was reading up on early designs like the old Fokker tri motors - they are built corrugated metal. This led me to discover that the corrugated metal is actually stronger than flat sheets for a number of reasons, and I thought to apply that to the foam board, and I found it not only provided the rigidity -but it also gave a decent leading edge. There are a few builds still on my wall that were somewhere in the middle that had 3d printed leading edge cuffs - and I liked those - but they added another step and another part - all for only a little gain - so I ended up moving onto the simpler folded over wing. All of it is an evolution of a thousand builds in the pursuit of distilling things to the simplest build that results in a good plane. I’ll always appreciate the guys building realistic models and I love stuff like Ramy RC and the like - they’re seriously amazing craftsmen, and I love watching and learning from them - but we’re all on different paths - and hopefully you’ll continue to enjoy my builds. Anyway - sorry to ramble. I appreciate your comment - thank you!

Nice. I would like to point out, that when you designing a sub250 plane there are people who would like to build a sub250 FPV also. Which means you need some additional electronics like the video transmitter and camera and that additional weight. For example Im building now a STRIX Nano Goblin which is like 65g(bare plane without any electronics, motor, servos etc.) I picked the smallest lightest parts and it looks like what's left is like under 100g for battery. Keep in mind I am an beginner, never build and rc before :D

I love FPV. If you have a look at my other videos, and my builds on the wall of my office - I build a lot of FPV planes. I’ll put more out on the channel as I get the time. I’m currently a DJI O3 guy - with a couple of air units. However, I am intrigued by the Walksnail system - as I see the air units are smaller / lighter. While I could make a “naked” o3 and strip off the case as some do, I’d be wary as that case is also a heat sync, and here in Phoenix - we need all the heat sync we can get. You’re going to love that nano goblin. I’ve got buddies with them, and I’m very interested. I’m actually waiting on the new design that was just on Kickstarter not long ago that’s very similar. The sub 250g thing is a tight squeeze to fit a digital FPV system, Flight controller, and any battery with much capacity. Most of my FPV stuff is over 250g, but it’s something I’ve thought about - it’s just still on the list for now. Thanks for your comment - and I’d love to hear how you like the nano goblin after you get it flying.

Great video! I've recently discovered that Li-ion packs don't have to be low current anymore. I use 4S2P soldered packs of Molicel 21700 P45B cells to power a Arrows Hobby Edge 1300mm plane. Pulls up to 75A, 1000W at max throttle. Each cell has a capacity of 4500mAH and can supply up to 45A continuous - so double those numbers for 2P. I manually solder my packs and include balance leads so I can balance charge them in the same way as a Lipo pack. I did look at using commercially available connection frames but found them too bulky for 21700 cells. I use tin/lead solder rather than spot welding - works fine so far - I've made two packs so far and flown dozens of times already without mishap. The drawbacks with 21700 cells are that they are bigger and heavier than the typical Lipo packs that they are replacing in my planes. But the extra flight time is amazing. I'm getting around three times longer in the air. Video of one of my first Li-ion test flights in a Dynam Waco 1270mm biplane: kzbin.info/www/bejne/qGOyf4ejoZmtiLs
@usefulaircraft18 күн бұрын
I love the li-ion cells. Don’t get me wrong - Li-Po still has its place in my sub250 stuff - but for my FPV or bigger builds - Li-Ion is my pack of choice. I started off with commercial packs, then tried soldering - and eventually built a spot welder, but then I saw the battery racks, and thought to try them after a particularly bad crash that punctured a cell. Sure, the battery racks weigh more - but the added capacity make it a non issue. For balance considerations - I just charge each cell independently, and monitor their internal resistance and temperatures at charging. If any individual cell draws my concern, it’s trivial to swap it out with a cell more similar to the profiles of the remaining batteries in that pack. I much prefer being able to isolate my cells completely for travel, as it (in my mind) reduces the risk of connected packs (albeit this may only be in my use case in a cramped carry on bag). I do have a few planes that fly off the 21700’s - and some that really benefit from their added capacity, but just be wary that unlike fuel tanks on full size planes, the weight of an empty cell is the same as the weight of a full cell, and it takes fuel to tanker fuel. So in some use cases - you may find that 18650’s could give you a better specific range due to lower cruise power requirements (because of lower overalll weight). But this all depends on if you’re solving for endurance or distance, and would require very exacting power control and testing. Most times - it just depends on the airframe I’ve built, or CG purposes. Either way - we’re really lucky to be flying with these amazing batteries. Cool video, and thanks for the comment!

@usefulaircraft18 күн бұрын
It’s really easy to over prop a motor. There are some efficiencies gained with larger props, or props with fewer blades, but once the prop is too large, the motor isn’t turning at the speed the ESC is commanding, and you start to see a heat rise that if left unchecked, will eventually burn out your motor (it usually just overheats, and the insulation melts on the windings, and the motor shorts out internally.) I’m not the smartest guy for sizing motors / props, and there are some builds I’ve used larger or multi bladed props that run the risk of burning out the motor - so I don’t always follow best practices. But have a look around online- there are some brilliant folks out there that really seem to enjoy figuring motor / prop combos. If I’m honest - I use a lot of cheap quad motors and props namely because they are inexpensive. You can spend as much money in this hobby as you want. I’m a fan of bulk buying cheaper parts so I can build more planes, and everything gets recycled into other builds unless I really love the design and it gets hung on a wall. Thanks for your comment!

@usefulaircraft18 күн бұрын
Control surface wise - they should be the same. Aerodynamically in full scale aviation, there are some studies about stall propagation in forward swept wings as spanwise flow can tend to move towards the root (however washout must prevent the tips from stalling first otherwise further pitch up will occur), and movement of center of pressure at differing angles of attack and throughout different speeds / Mach can have advantages for certain applications, but they do carry complexity as well (yaw instability), so you really don’t see many (X29, Hansa, S37). At the end of the day - my foam board wing was just something I wanted to build, with an aerofoil unlike what most use (but makes building planes super fast), and the plane flies well, plus I think it looks cool on the wall. I’d love to hear if you build something similar and how you think it flies. Thanks for your comment.

Hotwiring foam has been a great joy. I can make consistent 1mm or 2mm thick foam sheets for building even lighter. You can make stencils and cut out foam blocks for fuselage shapes then cut them full of holes and skin with the very light 1mm foam and it works great.

I appreciate the weeds! I plan to send my noob podcast listeners here so they can see a good example of a flying wing setup, what flight tendencies to look for, and the basic why behind it. Good stuff, thank you.

Surely you must know that you can curve foam instead of using the slats as you’re doing on the nose.
@usefulaircraft26 күн бұрын
Yep, many of my designs have curved surfaces. But every design evolves differently based on how it's cut. As this part is laid out on the laser, the cuts are on the outer surface. If I was making show pieces, I'd solve for the aesthetic, and she'd have a smooth nose. But I build these to quickly iterate and get out and go flying. I can go from a sheet of foam to a flying plane in under an hour, and that has value to me. Thanks for your comment!

You and Brett should try folding your wing around a V-cut in the foam. That allows a nice leading edge. Add a spar and you have an airfoil. You can even push down on that leading edge while it drys to form a lifting airfoil.

Very interesting! Had no idea the this transmitter had that capability. Thanks for sharing!

Great looking and compact bird! Too interested in plans or kit if you decide to offer! Been considering new build weights, where might I purchase something like the ones you are using in the video? Thanks!

I buy the 123 blocks off Amazon. They are a fantastically useful tool for many projects. You'll find a million uses for them. Thanks for your comment.

I’ll have more videos out shortly- I’m back on the road - so I’ve got to make it home first - but there will be more. Thanks for your comment.

Interesting timing of this video. Was just having a discussion with some folks on a Facebook group this morning about pitch trims at various speeds and I suggested they do a throttle to elevator mix for dynamic pitch trim so it would fly level through a more broad range of airspeeds (throttle positions).

I come out of full scale aviation, and trim is constantly in motion with power changes. I use the sliders on my TX16S constantly for my pitch trim as it falls easily under my trigger finger and it's great for a fast trim. Flying out of trim is just something we do in my line of work. We're always trimming for hands off flying. The mixing in the radio works great. And the slow up/down really works brilliantly in many situations. I cannot claim credit, but whoever integrated this gave us a tremendous tool. Thanks for your comment.
