a few suggestions: since it's a biplane- better figure out at least a rule of thumb for incidence of the two wings. pretty sure the top wing should be at a different angle than the bottom wing. don't do spin testing... stall fine, but don't try to spin it. It puts some huge stresses on the airframe, and it's really hard to calculate. also extremely difficult to bail out, or even deploy a ballistic chute when in a spin, especially if the plane is missing surfaces. configure the motors for tractor, rather than pusher. it will get clean airflow into the props, increasing their efficiency, although you will lose a little because the accelerated airflow will hit the motor mounts, but it's worth it, as the vibration will be greatly decreased. think Vicker's Vimy. use at least a couple of bulkheads in the fuselage. they can be pretty light. make the vertical stab and rudder extra big, because you will have no airflow over them from the props, and if a motor quits at low airspeed, you will need the extra control authority. Put some thought into the strength of the wings when the airflow wants to push them backwards, toward the tail at high speed. go ahead and make a third motor mount for the nose in case you need a third motor. and leave some space for extra foam in the nose to act as airbag.. pick your airfoil carefully. you are looking for high lift, a great stall curve, and low sink rate, rather than a good L/D. the L/D is almost irrelevant. probably at least a 14 % thick, flat bottom airfoil. a good place to start looking is a gottengen 398. Don't be too afraid to eliminate the wire bracing, or most of it, if it's really not necessary. you probably have lots of experience in that regard.. you might want to make some bracing for the tail.? focus on light weight, you can always re-enforce later, before flight, but it's hard to shave weight once you've added it. love this project! cheers!

oh, and make sure you make some horner wing tips from the start. they are perfect for your aircraft type. i just made a video on how to make them for a model. it would be directly applicable to foam. they will also provide a crush zone to prevent damage to the wings in a rough landing.

Thanks man! tons of useful insight! As far as spinning goes, I may have messed up a little on the delivery, I'll be testing deep slow flight characteristics at various power settings up high (some may initiate a spin) such as flying on one engine to determine minimum control speed. Thats where I'll plan on having the emergency chute, Most of this testing will just help me become acquitted to the performance (or possible lack of) so when flying 20ft over the cornfields ill know what to expect and how to handle it appropriately! I dont know the exact airfoil but I copied it off of a minimax, its a low wing ultralight design with many flight hours and the airfoil may be an ok first go at things! (its flat bottomed too, so sturdy construction should be easy) Thanks for taking the time to type all that out! I'll keep it in mind when proceeding forward!
@FPVREVIEWS7 жыл бұрын
Sounds good. As you have mounted the motors with the prop wash clearing the wings, the power-on stall should not be too big of an issue. Do try to get counter-rotating props, if you can, and make sure they rotate inward at the top. If you cannot, just be aware that there will be a critical motor, and that motor-out will be different between the two. keep them as close as practical to the center-line, but leave proper clearance, so that a bit of blanketing from a sideslip will not cause a loss of thrust. That could result in an ever increasing yaw problem, so leave a healthy space, but not excessive. Also better to angel the motor mounts so that the props are perpendicular to the actual airflow, which should be at somewhat of an angle of attack to the wing. you'll figure it out, and because the motors are near the aerodynamic center of pressure for pitch, the angle of the motors will only be critical to the efficiency, not for control.

Building something like this out of readily available materials may seem ridiculous to some but when done correctly and with the proper know-how it can be built and flown just as safely as any ultralight. I just read a book called "The Barnstorming Mustanger" and the writer described his first ventures into flight. He basically went to the hardware store and got fishing poles and bed sheets and some paint to seal the fabric and he made a glider that flew with relatively zero understanding of aerodynamics and flight. He was in his teens at the time and this was around 1920. People just dont seem to have the passion for aviation that they had back then. Very excited to follow your progress. Take your time and be safe and keep us updated with progress reports!

This is awesome. You can stop reading here if you like, and just soldier on. I'll still love watching what you do. I'm most worried that thing is going to be overweight. A little testing will show you just how thin materials can be. It's a little shocking to see the half inch ply there. Stuff like the the KR2 is made entirely from 5/8" square stock, and 1/8" ply. If you're gonna glass the fuselage, that thing is going to be structurally strong enough to be a cargo airplane. Or, do aerobatics. Provided you can keep the empennage on..... You appear to be somewhere between a KR2, and a SkyPup. The two designs don't really cross very well. They both are "stick" designs. The KR2 uses a stressed plywood skin to keep those sticks apart. The Skypup uses foam. Both the KR2 and SkyPup don't get fiberglassed afterwords. If you want to do foam and fiberglass, (which is a good design..) you should look at the Rutan designs. But it should be noted, that once you start to "wet out" anything, stuff tends to get heavy fast. "glass" birds tend to be somewhat heavier. Your method for determining control surface forces is.. not good. And can be quite dangerous. The surprising things you'll run into, is torque on the tail fin mounts. There's a book called "stress without tears" on amazon. It's cheap, and will ~really~ help you on this. I also recommend picking up the book "flying on your own wings." It's by Chris Heinz (of CH650, 750, 850, 2000) fame. Keep up the good work.

that's inspired a thought! if the lower wing is placed a little higher (12-14"?), the fuselage can be its main ski and only need a couple smaller toons outboard on the wings. might be beneficial helping lower the CG of the wing loading, and a little lower risk of a tip hitting the ground when taking off or landing. wheels could be added or removed for land or water. graft some 2" thick foam from nose to under the seat makes the pontoon step in the fuselage to release from water taking off.

@joshuawfinn7 жыл бұрын
Peter, looks like you have a design that will work reasonably well, so I'm not going to worry with that. What I do suggest are a couple of things learned from flying full scale.1. Do whatever is necessary to rule out the possibility of control surface flutter. It can and will actually kill you if you don't pay attention to it.2. You need a calibrated airspeed indicator. Its primary function is to keep #1 from killing you. No, really. That's the #1 limiting speed for light GA aircraft.3. Rig and angle of attack indicator. Much more useful than an airspeed indicator for avoiding stalls.4. Make sure you have some sort of turn coordinator, even if it's a streamer hung on a stick on the nose. Keep the plane coordinated, and even if you fail to heed #3, you won't bend your airplane from a poor landing approach5. Most important of all: take some measurements of control surface forces. This gives you important information for a variety of reasons, not least of which is making sure that your control linkages are up to the task. You may want to go so far as to fly the aircraft autonomously before you get into it. I know that sounds like a pain, but remember, you're not running servos anymore, so you have to resort to a bunch of linkages, and they're a little trickier than just slapping in a servo and a pushrod. Note, in addition to this, that heavier aircraft like Cessnas use a combination of cables and pushrods. Again, pay attention to the loads distribution. An aircraft that is just fine in terms of structural strength could fail fatally because the control surfaces are so high that a cable snaps or a turnbuckle tears out of its mount. This is probably the single biggest difficulty of a manned aircraft in comparison to a UAV--servos out in the extremities vs a human pushing on a stick.

@WRRocket99997 жыл бұрын
I think my original comment got ghosted from the links in it, anyway here it is again. Winding tow around the fuselage isn't really going to add much strength, unless you were making a pressure vessel. Winding like that primarily helps with hoop-stress. Which if you were making your aircraft into a pressure vessel that would be fine. But a tail of an airplane is mostly longitudinal lever loads. So Tow getting wrapped on like that isn't really going to add much unless you actually did some engineering design and filament wind it on. Still might not be the best application even then. Carbon has fantastic strength when you pull on the fiber. It has less strength when you try to push the fiber back together (compression load) As it is now relying on the resin to maintain the strength. Any time you are relying on the resin for strength and not the properties of the carbon fiber you are going to have very low performance. The resin is pretty much just there to keep the fibers oriented in a direction that they can do the most good. Carbon fiber also isn't a fix-all like everyone seems to think it is. It has some positive properties, but fiberglass actually has some properties superior to carbon (impact resistance and compression strength). But Carbon does have some great applications. I do have some general concerns over your airplanes general design. A scale model is a great way to get some general information about your airplane. But when you scale something up that much there are lots of little things that can grow into large issues. Like harmonic vibrations, some turbulence effects that are unexpected, the airflow changes when you make it bigger, etc. There is a reason why most people who build an aircraft go with a proven design. Even if they have the engineering chops for it. There are always tons of little things that you don't expect ahead of time that can bite you really hard. I don't think you will get sufficient engine power to fly your aircraft with hobbyking motors. Some motors that might actually give you enough power would be either the EMRAX motors, Or there are some hobby grade engines from Alien Power Systems that might work. A supercub is plane of similar size, but a bit heavier at @800 lbs. But also way more streamlined than your airplane. It has a 100 HP engine on it. The airplane does do 125 mph. And a minimum speed takeoff is around 40-50 HP being used. Drag is one of the largest consumers of horsepower in an airplane. Which the largest hobbyking motor I know of will just barely have the oomph to get it airborne on ground effect is my feeling. That is also running those motors at everything they have. Having a power margin is a great safety device in an airplane. Having zero power margin makes it so that any failure you have, is a catastrophic failure. My guess is your plane will end up being not that far away from 600 lbs when you get everything on it. I have made excessively large battery packs using Hobbyking RC lithium batteries. The one pack I made had 8 kW/Hr of power with 176 nominal volts and 35 Amp Hours. It weighed 125 lbs when all was said and done. Which is probably about the maximum weight you want to have in your plane. For batteries. You will also need to put most of the batteries in the nose of your airplane for weight and balance. With your motors near the back high amperage cables weigh a lot. Running 40 HP through the pack it gives you optimistically 15 minutes of flight time. Just enough time to takeoff make a couple of turns and turn around to land again. The final bit I will talk about is some things about general Test procedure stuff. Come up with an extremely detailed test plan. Do not improvise on it during tests. This is how you come back home to your puppy at the end of the day. Have people who have actual designed their own airplanes from scratch and are still living and flying their plane review your test plan and your design. Something you have to avoid at all costs is "Go Fever" Where you have spent all this time doing this, and will feel a lot of pressure from us and your peers to make it successful. Then you will choose to fly the plane when you shouldn't have. I have seen this happen to you on your other projects you have posted on your channel. I know this is a different project form those. This kills a lot of very professional pilots every year. No so much in testing their airplane, but flying into bad weather conditions, or trying to fly home with a part that is suspect. It honestly is a really hard thing to avoid doing, unless you are making a very conscious effort to avoid it. A parachute is also unlikely to save you. Though it does at least give you an option in some situations. Highest chance is that a mishap with your plane will take place at below 100 feet altitude. So even if you ditched perfectly you will still hit the ground with an unopened parachute. Also getting out of your aircraft will be much harder than you imagine it to be. Especially if you are in a spin. It could take thousands of feet of altitude for you just to climb out of it, especially when something has broken on it. There are classes you can take that will let you practice getting out of airplanes in abnormal situations. Typically this will be in a swimming pool and they will spin you a bit and dunk you in. I promise it will be way harder than what you think it will be. So honestly if I were you, I'd slow down on the building more. Don't set a timeline for completion. It's fine to set a mental one to help you get work done on it. But if it isn't ready you shouldn't fly. If there is something bothering you about the plane, don't ignore that feeling. Talk with others in person who have built their own airplanes. Don't trust testing that some guy on the internet did in his garage as authoritative advice on material properties. Be safe out there, don't be just one more of those guys that were killed by their own creation. I've had enough close calls in that regard to not recommend it at all.

I always incorporate at least two ways of mounting the wing in case one fails due to stress so I can fly it back. I would highly recommend that you take consideration in this idea, good luck man!

Playlist, wherein you can check the highpoints of my CV which pertain to this particular project..; start with my first Aeroplane hanging in the Inverell Transport Museum ("The 8Hp, 1975, Red Baron Skycraft Scout ; World's First Legal Minimum Aircraft.."), then there's my second Aeroplane, which isn't in a Museum but it was the ultimate development of "The 22 Hp VJ-24w SunFun ; World's First Ultralight Motorglider..." which I redesigned, rebuilt, carved the Propellers for, & did my own Test-Flying on...(as well as crashed it !) and there's also a Video in there covering my time as a Low-Speed Aerodynamics-Consultant (see "Aerotow-Launching Rogallo Hang-Gliders...; Development Of The Lockout-Index...")... Right, point one ; "SIMPLICATE, AND ADD MORE LIGHTNESS...!". That Rear-Fuselage you've built is already pretty much strong enough, and the proposed Woven-Glassfibre & Resin Skin will be more to provide Abrasion-Protection for the Foam than a neccessary addition for carrying Flight-Loads ; so adding a Helical-Wrap of Kevlar-String would be pointlessly adding weight, up at the back-end where you want it to be as light as possible. With an 18 - 36 MPH "Target" Speed-Range between Stall & Full-Throttle in level flight, you're not ever going to be able to pull much "G", and you're not going to be flying through Thunderstorms or major Turbulence either, so stressing the Airframe for any more than Plus-3 G. or Minus 2 G. is probably a pretty pointless excercise in adding Excess Weight...(?). There's a convention dating from the 1930s which holds that the Undercarraige should be designed to fail at 5 G's of Shock-Loading, because the last time anyone designed & built a Trainer with a 9-G Rated Undercarraige (to reduce the cost of Repairs following heavy landings...), their Test-Pilot dropped it onto the Runway from a 3-Pointer performed 20 ft up ; and the Undercarraige handled the 8-G Arrival really well, and the 'Plane rolled-out along the Runway, pulled off onto the Grass, & sat there with the Engine ticking-over at Idle...., the Test-Pilot's Neck had broken at 6 G's (as Human Necks tend to do...), and he'd died of suffocation while strapped into his seat, before anyone could reach him... So, that's one cautionary tale illustrating why "too strong" can actually be as big a killer as "too flimsy".... That Wing-Section of yours is pretty thick, therefore it's got a lot of Frontal-Area as well as "Wetted Surface", so when you add in the Cabane Struts & Interplane Struts & Flying-Wires & Landing-Wires..., this thing is goanna have a huge amount of Drag - the proverbial "Built-In Headwind..." ; so you'd better hot-wire some Leading-Edge & Trailing-Edge Fairings from Foam, to bind onto and streamline each and every Square, & Round-Section, Aluminium-Tube which your Design places perpendicular to the exposed Airflow. If you could afford to have Streamline-Section "RAF-Wires" made up for all the Bracings then that would be good, but I guess that you're goanna go with Round Cables (which have 5 times the Drag of a Streamlined Section the same diameter...) ; which is why it will be quite vital to put Fairings onto all the Struts. Attaching the Undercarraige to the Lower Wingspars, as the Model is configured, means that your Flying-Wires will be taking the weight of the Fuselage on Landing, rather than the Landing-Wires carrying the weight of the Wings ; meaning that any kind of heavy landing will likely break a whole lot of things, in the Wings.., and therefore it might be a better idea to mount a Bungee-Sprung Floating-Axle underneath the Fuselage, with 2 small Bicycle-Wheels (modify the Hubs to take Bushes on a Tube-Axle) with Fabric or Mylar Discs to streamline the Spokes (check my Video on the VJ-24w, and how I redesigned it's Undercarraige...). Having the Lower Wing so very close to the Ground, as shown on the Model, means that you'll be very DEEPLY into Ground-Effect, and floatFloatFLOATING a long way down the Runway, while you're flaring, and waiting for the Wheels to find the surface of the Earth... Other than those minor points, it looks like it should be quite a nice little Aeroplane. Are you goannna design & laminate & carve your own Propellers for it (?), to me that's the step which takes cobbling-up a home-grown Personal Levitation Device to a bit of an extra level...; building an Aeroplane isn't all that unusual, designing it for oneself is more rare, and making the Propeller/s for it is a degree of rarification indicating an outstanding level of dedication (obsessive-compulsiveness) & eccentricity... (aka, being in the grip of a significant Biggles-Fantasy...). The over-riding maxim, then, is that "IF IT LOOKS RIGHT, IT IS RIGHT ; and the only possible difficulty lies in knowing what looks right...(!). Such is Life, Have a good one... ;-p Ciao !

Hoping for a more detailed design video! It's fascinating to get a look at it. Here's my gut reactions. (Source: Bachelor's degree in Aerospace and Mechanical Engineering.) Firstly, I'd love to get my hands on some technical details of this aircraft design! Mostly because it's cool to see what people are doing, and also I'd like to proofread it a little bit. Mostly wondering what expected takeoff weight is, overall dimensions, airfoil choices, and powerplant. 1.) Motor failures- a sudden yaw near takeoff/landing AOA & altitude could send you into a stall of course. Maybe a good failsafe mode would be an automatic shutdown of both motors if one fails, with an override for turning it back on. I'm aware electric motors are pretty great, but I actually had a burnout on a twin motor at FFW which plunged my plane into the ground since my rudder wasn't enough to handle the yawing moment. 2.) Are you planning on instruments? I would argue for an Angle of Attack indicator- even if it's just a weathervane slapped on the side of the cockpit. The motor arrangement certainly would help this sort of instrument- making it easier to find a "clean" airflow to measure. Anyways, AOA indicator would be the very best stall warning to work with, needing no calibration with weather or altitude and works when in turns as well as level flight, unlike an airspeed indicator. This is particularly important since most stall-related accidents occur in turns at low speed, where a speedometer is somewhat less accurate. 3.) Are you designing the wing with stall mitigation? Will you use vortex generators or washout? Remember this would be to maintain roll control during a stall, not delay a stall or make a high lift system (high lift systems should stay away from light aircraft IMO). Other things like biplane vs. monoplane? A biplane makes sense (I wouldn't do it solely due to bracing complexity leading to more failure points), though in light aircraft like this you really don't desperately need extra lift (usually the thicker airfoils used are easy to keep light even in a cantilever monoplane). I really dig the forward cockpit- you'll have super good visibility!

have questions about the power of the motors and electronics im sure you'll answer in the next vids but dont trust glue man it can easily break if exposed to weird twisty heavy unpredictable stress reinforce it with something else not other glue coz sometimes they cancel each other also consider making your cabin with thick layer of foam so if the worst happens you'll be fine not to be rude again but also plan the worst if you crash make sure nothing heavy will hit you in the face or on the back ......safety first mate......... knowing you i have no doubt that it will work ....have fun

some suggestions on structure and safety: i highly suggest to laminate some fiberglass in the inside of the fuselage, maybe just the highly stressed parts, as well. consider fiber direction and the forces they have to take. fiber/foam/fiber is much stronger. the foam with a outer layer of glass alone does not ad much stiffnes and cant take bend and torsion forces well. the wood will take some load but keep in mind also vibrations, humidity, weak gluejoints and hard handling on ground. i dont know the numbers of the plane but relaying just on the glued wood spars seems optimistical. take a look on some infos about sandwich compositelaminat. integrate some sort of a crashbox in the cockpit section. a combination with glass, foam, carbon or aramidfiber of some sort. in case of a accident you will most likely crash nosedown. add some sort of piercing protection would be ab good idea as well. wood and carbonfiber can impale you when it breaks. consider that jumping out of a cockpit with a parachute is realy hard. and you have youre wings behinde and above you. there are ul-recovery systems with the parachute atached to the plane. good luck!

Peter, you really need to research home built aircraft framing techniques and follow them. Don't just watch a few KZbin videos. Use the same materials and practices where possible. You mentioned using Gorilla Glue for example, what are you using to activate it? I would use a good aviation grade water based wood glue; then you have two separate glues that reinforce each other as they set. You also need to clamp those wood joints when you glue them. By the way, I noticed several comments below providing suggestions and "engineering advice" and some had grammatical and spelling errors and a few were from people with names that sound like breakfast cereal box hero's or online gaming avatars. I don't think I'd count too much on their advice, especially if you're even half way serious about this build. What about Austins dad, he built a nice plane and I'd bet he'd help, maybe even sponsor you in some way?
@PeterSripol7 жыл бұрын
thanks Tom! Will do! I did take some inspiration as far as gussets go and glues! the gorilla glue is just for wood to foam adhesion, all wood to wood construction is done up in T-88 and pieces with really good fits and surface area are done in wood glue. And yeah I saw that too! the only partially credible ones are maybe aircraft mechs, but they're not structural engineers which would dictate whether or not this thing will hold up in flight!
