Flying an Experiment STOL Concept Plane!

[@Cyndertruly]

the ksp music goes hard to this build. good choice lol

[@Bassalicious]

I was about to say that. sets the mood right, solid choice.

[@DFMurray]

Fun fact, The developers of KSP1 didn't have enough funds to hire out all the music. So they used copyright free music. I think the majority of the music they used is actually in the KZbin copyright free music library.

[@williamfawkes8379]

Those wings are really nice. You've got a lot of room to wiggle out weight from the fuselage. Remember that your opponent there is using a skin to cover gaps, and you can do that too in many places.

[@floppyhobbies]

Of course. It actually turned out where the wing was super heavy and the fuselage super light (for the size). All those complex mechanisms in the wing made it super heavy but the fuselage is just empty space for the most part!

[@williamfawkes8379]

@floppyhobbies that makes sense. Would making huge rectangle holes in the solid section of the wing, then skinning it over make a difference? Can add some bracing if needed, but probably only a couple max. That wing is so cool looking, I am super jealous.

[@floppyhobbies]

@@williamfawkes8379 I don't think that would make a huge difference to be honest. The weight of foamboard per square inch is actually super low, especially since if you take the paper off you remove 70% of the weight. It's so light that it's almost as light as covering! The heavy part is any glue joint (hot glue is heavy), and the cardstock skin I'm using for the flaps which is heavier than foamboard per square inch. So the fact that I had lots of small ribs in the wing and complicated multi-layer cardstock skins for the spoilers and flaps really added on to the weight. TLDR: I wouldn't be able to poke holes in anything heavy, since it needs to be that complicated shape, and anywhere I could make an opening wouldn't actually be responsible for much weight and wouldn't be worth the effort. That all being said, I'm working on a building technique to more closely mirror covered balsa, with foam taking balsa's place and using covering over foam ribs. Keep an eye out on the channel, it'll definitely appear on a project at some point in the future if it turns out to be a worthwhile technique!

[@phr34k86]

Now add decently sized slats to that wing and you'll beat the competition! But as you mentioned that the wing is fairly heavy I'd suggest to add fixed slats.

[@svkusi]

Same, keep the flow attached!

[@ChainsawFPV]

It looks like something Mike Patey would design! Beautiful!!

[@JustPlaneSilly]

Mike Patey is the GOAT

[@eaglepursuit]

Beautifully done. I had always wondered why I never see spoilerons and full flaps in STOL aircraft

[@svkusi]

That's a cool concept.. it is an argument for the tricycle gear as per full size zenith stol.. Maybe slots on the leading edge too, to keep the wing flying at the higher aoa?!

[@HciContractor]

What a great flying plane with really cool flight characteristics 🎊 🎉🎉!! Seriously it's very cool. I'd love to build that myself. You did a great job! I think I'd hand toss it an belly land it. It's a good plane to 3D fly!

[@stenic2]

The buffeting tail on the 79 plane during slow flight is funny

[@Mate2Frio]

Now look at Mike Patey's wing design that extends the front of the wing as well.

[@athenovae]

I’m so glad I found your channel through tail heavy! Great work! Love your energy, enthusiasm, and work. ☺️

[@limadeltazulu]

It looks a bit like a PZL-104 Wilga aircraft :) And wing mechanisation like Draco, The most badass monster aircraft. :)

It’s happy (when tail wiggles 😂)

[@jvedra9041]

Vab music makes the build hit

[@Cyndertruly]

also tilt the motor 1-2 degrees to the right to reduce p torque. this is because you use an electric motor. the induced drag on the flaps will increase the issue.

[@Cyndertruly]

if you do this you can perform high alpha maneuver's.

[@PrenatalApocalypseNow]

The greatest man-made wing to ever taste air! Changing an aircraft's flight characteristics by changing it's wing shape! Just like the birds do!

[@WindCatcherRC]

This has got to be one of the coolest planes I've seen today!

[@김재욱-w8v]

nice wing mechanism there, but the low polygonized fuselage is also impressive!

[@sparky6200]

Fowler flaps & Flaperons on a homemade STOL. You're the shit buddy. I'd be interested to see the in-flight with-power difference with that cowl addition on & off.

[@floppyhobbies]

Thank you! It would be cool if I had any data on that. Just from how the plane feels, it doesn't really make a noticeable difference but it would be neat to see the numbers!

[@__pie___]

Reminds me of the mitsubishi MU-2 a turboprop twin that uses full length flaps to allow it to land on shorter runways with a higher wing loading, and spoilers for roll.

[@SupernovaSpence]

If you had leading edge slats, you would’ve won hands down.

[@coriscotupi]

Brilliant. Well done, sir.

[@danielskoog5565]

Epic build! I bet if you added slats or vortex generators on the wing it would out perform the competition.

[@TomS-j5e]

I'm no RC guy, but maybe you can build a magnetic battery connection that clicks together like the older microsoft surface tablet charge cords. Apple may be doing something like that as well. They also have some magnetic clasps for various ski helmets. Anyways, the idea was a bit of a whim after seeing you struggle with the battery connection. Appreciate the content!

[@MiesvanderLippe]

The packs they use are often quite low voltage / high amperage. Longer leads would’ve helped haha.

[@floppyhobbies]

Yeah, longer leads are definitely on the list of things to add!

[@Gostwick]

Weaponised something or another! Impressive

[@sashgorokhov]

[@ohwell2790]

They are called spoilers and disrupt the air flow and lift just like on airliners shorten landing roll. Of course on this airplane just a neat little touch.

[@goldnoob6191]

Building an airliner wing for your model ? 😊 Airliners control surface are tied together and ce central control system dispatches according to flight envelope, it' s almost impossible to achieve good control without a flight controller tuned for your plane, this also include softwares support for your configuration and/or a really smart TX. Also you should never turn off the engine when slowing down the propeller acts like an air brake ! It very noticeable 😆. You have openTx add some mix to limit engine rpm when airborne ( flight mode or specific input ) the spoilers should never be available in normal flight mode, just take off/ landing, allowing you to smooth transition between modes with delays or specific curves (difficult)

The plans are a total mess right now, some parts have plans and other parts I just made up on the spot as I was building it. I would like to make a V2 at some point, and I'll probably make better plans for that. No idea when I'll get around to doing that though lol.

Are you cutting dollar tree foam board with a glow forge, and if so what model? Also, what software are you using to model, and do you have recommendations?

[@Nilezy]

Can achieve the same characteristic's with a flat foam board, and this is before digital radio's being able to mix the channels. All I had was a two channel mixer board. but enjoyed the unique, experimental designs

[@keppscrossing]

Looks like a faceted PZL-104 Wilga.

[@Chazz155511]

I'm curious as to what cad process you use. Specifically what software and how to go from 3d model to layout for the laser cutter. Or do you keep the geometry relatively simple and simply sketch it out in 2d with a lot of mindfulness?

[@floppyhobbies]

I use Inkscape to design the airplane. I do not go from 3d to 2d, instead I design in 2d. My process essentially looks like getting a top profile, side profile, and cross sectional views of the fuselage at different points, and then using some simple math to make the transitions between them. I remember when I was first starting I had really wished there was a video explaining how to design an airplane like flite test. Maybe I'll make a video like that soon!

Huh, the rc clubs in au tend to have holes to slot in metal guides to allow protected power ups.

[@simitarknut2201]

I have a TX 16 too, how do you program the spoilers? I have a large sailplane that I want to do that to, rudder alone isn't enough on breezy days.

[@floppyhobbies]

So what I did was a I made a new entry in the inputs tab that I named SPLR. I set that up on a switch so that when I flicked the switch the channel value would change -100% to +100%. Then, I went to the spoilerons in the mixing tab, because I had a separate mix for each spoileron, and I mixed in the spoiler input. I hope that helps!

[@David-yy7lb]

Add some slats that will help alot

[@pareckattil]

What is the stall speed on this beauty?

[@flymachine]

Someone had been watching MP 😂 Spoiler alert - I don’t quite understand the practical application of the spoiler but I guess it’s an interesting experiment.

[@floppyhobbies]

If you look at 12:43 , you can see Zach use the spoilers for their intended use. He's able to descend almost straight down while still retaining control. I imagine it could be used to land in areas where you're too hemmed in by trees to make a normal approach work. Either way, I think it looks cool!

[@chickenychickens07]

Can I know what programme did you use with the wing and the plane?

[@floppyhobbies]

I actually design in Inkscape!

[@chickenychickens07]

Oh my

[@edcew8236]

The Lockheed L-1011 had direct lift control somewhat similar to your power/spoiler concept. Also, spoilers don't work all that well for roll control on full size general aviation aircraft.

[@floppyhobbies]

My inspiration was the F-14 in landing configuration with the DLC switch enabled. Also, the Mitsubishi MU-2 has full span spoilerons. It's not a common configuration but there's certain problems it solves well!

[@9e05cherianpadipurackalvar6]

went so far to get proper flaps but no slats :(

[@floppyhobbies]

[@SafetyThirdRC]

Wow Sometimes one thumbs up is not enough. For some reason I get my jollys from slow flight and this buid seems to defy the laws of physics. Would moving the main gear forward a 1/4 of an inch help ground handling? I hope hobbie grade manufacturers are watching you. Fly it like you STOL it. Cheers

What laser are you using?

[@floppyhobbies]

I use a glowforge.

[@loebair]

cool stuff! :D you should check my 4m PC6 with 5,6kg takeoffweight

[@ChrisWantsToKnow]

I think you won the competition actually, because your opponent uses more the propeller than the wings to stay in the air. Someone even says "Do airplane mode." when he does half helicopter mode. But your airplane can do helicopter mode even better, as we see at 12:31. So in helicopter mode your plane does actually fly slower than the other one. And also if both planes would do pure airplane mode I guess. Helicopter-mode is considered cheating imho. So why not trying to fly slow in pure glider mode without the motor spoiling the result?

[@floppyhobbies]

That's actually a really good idea for testing slow flight, the next time both those airplanes are out at the field I might try that. I'll be sure to reply with the result here if I do!

[@Cyndertruly]

your top speed brake needs to overlap with the controllable flaps. that's why it tipped forward as it provided downforce before the cg.

[@Cyndertruly]

it will reduce control efficiency in terms of energy retention so you might need a larger battery.

[@Cyndertruly]

if you want an easy fix, bend the gear slightly forward increasing the rake and reducing drag. it will increase speed and allow for a larger battery aft cg.

[@floppyhobbies]

They actually do overlap! I only experience downforce issues if I'm travelling at high speeds when I extend the spoilers. I think that's because they act less to stall the top of the wing, and more to increase the pressure on top of it, making negative lift. At lower speeds, they just kill the lift and it works exactly how I wanted it to.

[@Cyndertruly]

@@floppyhobbies that’s awesome. The f-16 style ailerons made me laugh seeing them on a high wing.
