Pancake Motor Twin Build and Flight
Переглядів 1 тис.21 день тому
I said I'd get the pancake motors built into something that counters the torque better than my pancake single build did - and here you go. This project became a bit of a thorn in my side - it got interrupted by work, and had a few component failures that required rebuilds and redesigns - so it took longer than I expected. Nonetheless - I eventually got something into the sky - something akin to...

I think everyone wants to be a bush pilot. I know I did. While I can't afford a Beaver or even a Cub - my DIY RC Bush Plane scratches that itch. With 3d printed landing gear that's holding up amazingly well, this is a really fun plane to go play in the bush. Flaperons, Rudder, Elevator - it's all there. Just a great flying plane. Enjoy.

    You can stack flat templates to 3d print with a .2 mm gap with ironing and and peel them apart after printing, but only if they're designed to be the same size or fit in the foot print of the one below it. A little bit of design magic to do fewer prints would make this very convenient.

    3D printed plans are an intriguing idea. I'm not sure that the benefits (template durability, no page scaling challenges, no need to cut out the paper template after printing) outweigh the drawbacks (bulky, requires a 3D printer) as compared to paper plans for most people.

    I make foam board planes and print 3d parts like you do for motor mounts etc. Mine are simpler though, more like the Experimental Airlines style. Giving the stl files to 3d print is a great idea but I think there will be a couple of problems. I find to cut foam board, I need to keep the craft knife at a very flat angle to get a clean cut and with it at that flat angle any tight curves are going to be problematic and you have a few of those. The second problem is I think there is a high chance you will end up cutting into the PLA itself, hand cutting foam board is really better done against a metal edge. You also mentioned the difficulty in getting accurate to scale plans. Plans are great for balsa models where the construction is largely air and you can see through to the plan underneath but that doesn't work for foam, you can't see the plan anyway. What I would need would be dimensions only - i.e. this line is 30cm long and at an angle of 10 degrees, it doesn't need to be to scale. I would then just copy those dimensions onto the foam board (as I do at the moment) and start cutting. Keep up the good work, great channel!! Cheers!

    That’s a great idea. I sometimes print templates on a 3d printer cause it usually ends up being faster than a regular printer 😂 (no joke). That being said, personally I don’t have the patience for printing big stuff. The motor mounts and stuff would be fine, but I’d just wing it for the rest (pun intended). 25 USD would be too much for me though. That swappable dji mount with the dummy load is genious btw 👌

    The idea is great! Just keep in mind that for $25, you can buy a 3D-printed plane. If I had your skills, I’d try to make the design modular. That way, after spending $25 initially, the rest of the modules could be more affordable. Just a thought!

    I tried making the Drag Queen and had many issues hand cutting it because of the curves. I’d suggest maybe exploring the free plans that Flite Test creates. I did their Mini F22 and their plans were well made with some nice ways of cutting in the areas that fold over and such. I printed your STLs for the Drag Queen and they were great. I’d pass along the link for the Flite Test plans I used but UA-cam tends to hide links in comments. Interested in what you have? Absolutely. The plans need to be refined some. It’s a great start though and I’m thankful for your efforts in the videos and helping new folks get into sub-250 builds. You’re a champion!

    • @spindash64
      @spindash64 20 днів тому

      And more lift: the propeller wash should counteract the wing vortices, lowering induced drag Looking at that first toss, it seems like the propwash in conventional arrangement was forcing the wing to work even harder to make any useful lift, keeping it from gaining any altitude

    • @usefulaircraft
      @usefulaircraft 20 днів тому

      My choice to have the propellers rotate inboard was not accidental. I’m sure you’re familiar with P-Factor. It’s what causes the descending blade of the propeller to generate more thrust than the ascending blade - particularly at high angles of attack and high power settings. So I had to decide how to best use this to my advantage. As I was solving for slow flight (I fly in a confined park) - I felt it best to have the counter rotating props turn inboard so that as I was operating close to a stall - that thrust vector would be closer to the centerline of the aircraft in the event of any difference in throttle response. This configuration is common in multi engine training aircraft. While it is true there are planes where the propellers counter rotate outboard have better performance, they sacrifice low speed handling and will have a higher minimum controllable airspeed. I had already fought a defective ESC, and had motors that didn’t spool up at the same speed - so I chose inboard rotation to further minimize any additional potential asymmetry.

    • @usefulaircraft
      @usefulaircraft 20 днів тому

      The inability of the conventional (tail) designs to fly was because the elevator could not generate the pitching moment at the speed of my throw. Had I launched into a stiff wind, or by means to gain a higher airspeed - it would have flown. The wing is an inverted KFM - its lift is a direct function of angle of attack. The plank design is actually hindered by the fact that the elevon shares the duties of an aileron and an elevator. Furthermore - when elevons are functioning as an elevator, their effective arm (in a plank) is much shorter than in a conventional design where the elevator is much further aft. The saving grace in my build was that the entire wing (save 20mm at the root) was in the direct induced flow of the propeller - and thus had the effect of power steering (by the induced flow being vectored by the elevon when the motor was powered). Before I flew it - I would hold the airplane at the CG, and could feel the pitch and roll forces while the propellers were turning. As far as the wingtip vortices - they were swimming in a confused sea. The propellers extended 80mm beyond the wingtips. It was an interesting exercise, and I learned a few things, but I have no desire for a carbon fiber haircut - so that plane is parted out.

      I started with gliders and whatnot - I do enjoy them. My very first build was an old Wanderer glider. That plane was a monster to transport - but flew at a walking speed. That said - I live in Arizona - so I may not be the best judge of what a good thermal plane is - out here it gets so hot you could toss a rock into the air and it may catch a thermal and fly away. It’s been a long hot summer. Thanks for your comment. You’ve planted a seed.

The water chiller is a CW-5200. Otherwise I’ve got a generic fume extraction fan, and a small compressor for air assist. It’s been a workhorse for many years.

I’d love to fly one - but I wouldn’t volunteer to be a test pilot on them. For my use - I like the idea of tailsitter FPV stuff where the camera pivots for hovering operations, and then tilts to follow the relative wind as the plane transitions is pretty cool. One day.

    • @usefulaircraft
      @usefulaircraft 18 днів тому

      I'm using a CO2 laser. It's a 100W tube, so I'm running it at low power and high speed to only cut the top layer and melt some of the foam. That works well for the hinges. The cuts are just that- higher power and lower speed. It just takes patience and time playing with your laser to learn the speeds and feeds that work best for you. Try a local maker space and see if they have a laser you can learn on. That's how I started. Thanks for your comment.

    • @usefulaircraft

      Sorry for the delay - work disturbs my hobby sometimes. I don’t hold true to the percentages. I started holding strict to the numbers - but for various reasons I fell away from them. Furthermore - I later flipped the wing and didn’t change anything and it still flew. At the end of the day - I think the bulk of my lift is coming strictly from AOA. It’s the kid with their hand out the window of the car feeling the changes in pressure when they rotate their hand. I guess I’m a heretic in the church of plane building. Build it and see if it’ll fly. Works for me.
