Motorfloater Flying
Вставка

- Here's a music video mix of motorfloater flying in my Bloop 3, up to April 2016. The Bloop is a homebuilt ultralight airplane of my own design. It was built to fly as slow as possible, for easy flying, comfort and safety. I call this kind of airplane a motorfloater, it has a wing loading of less than two pounds per square foot, it is slow and simple, has a small engine, and the pilot flies completely out in the open. I also insist in having the propeller in back, so the pilot does not have to be shielded from the propwash. For simplicity, the Bloop has two axis control, meaning that it is flown with just the rudder (foot pedals) and elevator, there are no ailerons. Ground stops are made on either the nose or the tail, as the pilot wishes, because the main wheels are located at the center of lift, creating near neutral balance on the ground. Notice the changes during the video in the rudder pedals and nose skid, this is a Part 103 ultralight so I can modify it as I please. Sensitive to drag, as always, I tuck the cuffs of my pant legs into my socks. Details and comprehensive technical drawings can be found on my Bloop website, m-sandlin.info/bloop/bloop.htm .
My latest motorfloater is a monoplane: m-sandlin.info/Bluebird/Bluebi... - Наука та технологія
Just brilliant. As back to basics as powered flying gets, I love it
This is the most fantastic flying machine I have ever seen. I would love to have that over here in England - awesome!
Just read about this on the website and I absolutely love it. Combines aviation and inventing/making - two of my favourite things!
Thanks for posting this! Looks like a ton of fun! That's the way flying was meant to be,by the seat of your pants,and the wind in your face.
Love it! Like stepping back to the beginning of powered flight only better!
Hello.
This is a fantastic bird so bear with my comment as a licensed instrument pilot with a Cygnet SF 2A. Me being who I am would add a front fairing..(part of my cowardice) and some lower pushrod ailerons ( to make me feel better) and have a perfect ( in my opinion) biplane that harkens back to the thrill dream days of flying. Now take it one more step ( I am an experienced builder ) and add another seat to share the joy of flight with ( now I've complicated your incredible bird) and again...another dream flight machine that makes this 56 year old kid smile ear to ear.
Great Job!!!!
All good points. I suspect that restricting the pilot's vision with cockpit walls or a fairing actually would increase confidence, whereas seeing too much could be a burden that the pilot will have to adjust to.
I suppose the pilot fairing is mostly for wind blast protection. It might not be wanted on a motorfloater because the headwind is mild and the fairing will just restrict the pilot's position.
Lots of instruments to look at would also be good (I am not being sarcastic, pilot confidence is a big issue and the factors involved should be acknowledged). Ailerons and pushrods may add confidence also, but little functionality I think.
A second seat cannot be used on an ultralight but could be flown on a plane in the Experimental category. A much larger wing area will be required to keep the wing loading low (less than 2 lb./sqft.) so it can still fly like a motorfloater. You want the special benefits of flying slow!
Yep that's me. Only basic instruments and still open cockpit:-)
Awesome grass roots aviation. Well done!
I'm an old man who always wanted to fly, the Dehavilland Beaver was my dream plane maybe in the next life 😊 really enjoyed your video!!
Отлично ! Просто сказка , ощутить себя птицей ....
Incredible, I fly a trike and this seems amazing.
Amazing!
love this little plane.
Floater is appropriate! Pretty cool.
Lovely plane !
Wonderfull job !
Great work..🖒🖒
looks like so much fun..
Very good I really want one of those asome!!!!
Verry good..👍👍👍👍
I think thats Otay lake glider port... thats where I got my glider rating back in the 80s. No hangers then.. only a 16 or 18 foot trailor that served as the office. we had Three runways - two for take-offs and one for landing.
amazing
SENSACIONAL.
Caramba, ese avionito me gusta mucho, muchísimo!!!
@airchairp thanks Michael sir but my problem is that B2W8 and B2W13 .how will they stay dihedral
by just connecting with bolt.. the wings will drop (opposite of dihedral) just by weight of the wing.( If you get the picture of what I am saying)B2N3,B2W14 B2N15, B2E7, B2E8
I love his safety gear
Vintage REI rock climbing helmet with cut outs for ear muffs. Also, total recovery parachute, shoulder harness, and eyeglasses so the bugs bounce off. My (airport required) aircraft radio might be a safety item, but I it can be a distraction and I might not use it under some conditions given the choice.
Fantastic! I love the slow fly, do you did the project? is one of my favorite fly machine video.
Even the Wrights had aileron control! (which they coupled with the rudder0
Great..👍👍👍👍
the best
Laissez le bon temps rouler…. Bravo mon capitaine..
Your aircraft made me crazy.
I watch it again again again and again.
That's a pretty cool things to ride as transportation.
Unfortunately, there's no videos how to make it.
It would amazing if you make the video how to build it.
Greetings from Indonesia.
First things first! Tell me that you have seen the website, especially the online viewable drawings.
@@airchairp I've already seen it. Just don't know wich part should I do first and how to do it. And I hope you could help me part by part from the bottom detailly.
You're right, the drawings are not a recipe or plans for construction. I cannot help individual builders for lack of time and liability reasons. Look at builder videos and the Airchair Yahoo group, but don't expect much activity yet, motorfloaters are sparse and new.
@airchairp thanks Michael sir, but my biggest worries is that if I built my bloop2 according to drawings will my wings get the dihedral angle 6 degree?????? (B2W18,outboard edge higher than the inboard roots edge)B2W13 and B2W8..
The 6 degree (polyhedral) angle of the outboard panel is adjustable by design, you can re-rig the cables to get other angles for a different yaw response if you want it. The six degrees is not an exact requirement, it's just an angle I have used before with satisfaction, it is a common dihedral for low wing general aviation production aircraft.
From the Bloop2, the 3 features a third-or-so less diedral; what impact has this had on performance, handling?
+The Bloop's polyhedral wing panels are now outboard of the main structure, so they can readily be rigged to various angles for whatever yaw/roll response is desired. My wings are set at a relatively low angle for sedate handling, like a typical training or recreational airplane. "Performance", in the tradutional sense of speed and climb rate, does not seem to be much influenced by moderate changes in dihedral, or polyhedral wing angles.
Great
Mike, can you help me get my long-time-hang-glider-pilot head around something? Say you're on approach, 30 feet off the deck, and a thermal lifts a wing- how is the wing leveled without changing course? Or is a course correction absolutely necessary? I imagine the rudder would be used to point the high wing down wind until level- is that right? How effective is that for quickly righting a wing? I wonder what the highest bank angle you've flown with the Bloop, and an approximation for the amount of time required to make 2 reversing 90 degree turns. Thanks much for your time- and inspiration.
+I don't have any data on how quickly I can turn, and I wouldn't know what to compare it to, anyway. When you are flying slow, you usually have lots of time to react and do turn corrections, as you would have in your hang glider. Most pilots who have flown rudder/elevator control systems seem to accept them as adequate, and I have no desire for ailerons on the Bloop.
+airchairp I'm sure you appreciate the place the questions come from; we can choose our launch conditions- but things can change while in the air. While a conservative ethos provides a long flying life, the ability to recover from unusual attitudes is a critical/fundamental characteristic when assessing very light aircraft, and the above questions were asked with those values.
Great airplane, but I really would like ailerons.
Moim zdaniem przy tak lekkiej konstrukcji bardzo istotne jest idealne wyważenie samolociku. Nieprawidłowe umieszczenie środka ciężkości może spowodować łatwy przechył i wypadek. Wyważanie trzeba przeprowadzać zawsze pod wagę pilota i silnika. Ogólnie jestem pod wrażeniem i naprawdę zazdroszczę.
Translation from Polish: "In my opinion, with such a lightweight design, it is very important to perfectly balance the plane. Incorrect placement of the center of gravity can cause an easy tilt and accident." My motorfloater experience seems to be quite contrary to this, heavy pilots seem to do alright, though they are nose heavy and have to hold back stick pressure to keep the nose up. I have not seen any flight with an aft balance (too light a pilot), that might be hazardous and need not be allowed because it should be easy to put weight forward in the nose.
@@airchairp Więc ma się rozumieć lot tym samolotem jest bezpieczny. Pozdrawiam.
What is the brand of the recovery chute? Thank You for the great videos. I currently own a Bensen B8M Gyrocopter with ken Brock upgrades but, I would love to build one of these for the simple reason of being able to climb out of my property with ease.
I used an ordinary hang gliding chute. High Energy Sports Quantum 440 with a 20+ foot inline
bridle, paraswivel, and deployment bag (now on Bloop 4). This can be carried on the side of the nose in an Advanceguard cockpit reserve parachute container (see it on Bloop 2). This is all on the drawings and can be downloaded in detail, see the website.
I operated off a five hundred foot dirt runaway without much trouble. Perhaps unlike a gyrocopter, a motorfloater needs two or three times as much runway to land as to take off, and that is what determines the size of the airport you need. One reason I favor small engines is they are light and allow shorter landings, thus allowing operation from shorter runways.
@@airchairp Thank You.
I have a hang glider trike man that is a small engine Superlight awesome
Is there a specific NACA airfoil that you used in the Bloop's creation?
+Each of the three Bloops has used a different airfoil, none are specified by any system of documentation other than on my website. There are almost no ultralights that use a well known airfoil. With few exceptions, no one seems to have sutdied the airfoils that are actually in use by hang gliders, paragliders, airchairs, or motorized ultralights.
I want one lol!
would you be able to fly this out of an uncontrolled airport with FBO permission? Would it be illegal to fly it 60 miles north to Oshkosh as long as I avoid other airports and do an I Fly Roads kind of deal.
Ultralights fly accoring to Federal Aviation Regulations Part 103, so I fly in daylight over uncongested areas in unforbidden airspace, obey right of way and visibility regulations, etc. Many ultralights fly from airports with management permission, as I do. With my half size fuel tank, I might be able to fly 60 miles with a tailwind. To land at Oshkosh, which I assume has a control tower, I might need a radio.
Great work sr, ilive near to san diego, were i can meet and learn to fly it? thank`s
Learning to fly a motorfoater is hard to approach. True ultralight airplane flying is such a rare activity that we don't have a training system. Either you go Plan A (get a regular pilot liscense, takes a year and a dozen thousand dollars) or learn to fly hang gliders (my favorite) or paragliders. The transition to a Part 103 airplane often goes through Sport Class open cockpit flying (also getting rare) or paramotors.
Mam kilka pytań i byłbym wdzięczny za odpowiedź - waga samolotu, rozpiętość skrzydła, pojemność i moc silnika oraz użyte materiały?
Go to the website (in the video description) for all those details!
@@airchairp El caso es que no conozco ingles. De todas maneras gracias por haber contestado. Quizas ya
yo sé algo de esas cosas: el peso de avión no mas que 150 kg, envergadura de alas mas o menos seis metros, el motor 250 cm y 36 kM, aluminio y lona alquitranada.
Saludos cordiales.
Wah mantap
Talk about all the runway you didn't use!😆
I thought you were giving me a hard time for overshooting the runway, but now I think this is intended as a compliment about not needing much runway to land or take off, so yes! Motorfloaters!
However, overshooting the runway on landings is a real issue. In the videos you can see that I have to come in over a hill that prevents me from using the first part of the runway (I can't come in steep enough without speeding up), and then I get low and float down the runway a long way before I lose enough energy to stop. As you see, it is the landing that determines the size of the airport you need. This is why a bigger engine requires a bigger airport, the engine is dead weight on landing and a heavier engine will make you land faster and with more energy, thus requiring a longer runway.
If I were to add a new control it would be an air brake (not ailerons), allowing steeper landing approaches and reducing the roll out distance.
How many fuel stops to get to Oshkosh? I did it with none (1,600 statute miles) in my LongEZ. Yeah, apples and oranges. I'm still thinking about building a Goat, get back to my hang gliding days which I miss.
Yeah, mines at least 8 inches.
Hi! Do you know the stall speed of your biplane airchair?
I actually designed, built, and flew some biplane airchairs, the Bug 2 and Bug 4, for instance, which were car top transportable gliders that roll launched off hills or by aerotowing. Now I fly the Bloop biplane motorfloater, which I don't call an airchair because it is not a glider. So, I'll write about my motorfloater, even though the answer is the same.This question implies that there is a stall speed, I know when I get there, and I care about it (three questions, actually).
There is no abrupt or violent change of attitude, nor any great loss of control resulting from an unaccelerated slow down, no definite stall. Flying with full back stick, with a light pilot at low power settings will get you a gentle nose dip, otherwise you just get balky control and a high descent rate.
Yes, you can see and feel the transition to high descent rate, if this hapens on final landing approach I usually speed up a little to get back to a lower descent rate to avoid excessive banging of the runway, which is hard on the landing gear.
Do I care about the effects of flying slow? Not much, flying too slow is not the real hazzard at light wing loadings, other situations are more deserving of attention. I think a paramotor, paraglider, or hang glider pilot would give a similar answer, noting that extreme slowness could be a hazzard in particular situations, but it is not the critical pitfall that you have with standard aircraft. Many hang glider pilots fly with airspeed indicators, but these are mostly for performance reasons, not for avoiding some critical minimum airspeed.

What kinds of wind will this plane handle? Sorta like the old air pup
Another pilot flying a motorfloater similar to a Bloop 2 reported that 10 to 15 mph. winds were excessive. I like to fly in mild winds. Calm air is okay but a headwind makes takeoffs and landings easier because the ground speeds are slower. In strong winds, gusts and turbulence are the issue, and the light wing loadings of motorfloaters will result in bumpier rides.
No ailerons? What do you do for roll control?
Roll control with the two axis system works fine, it comes from yawing the plane with the rudder and letting the yaw/roll coupling of the airframe do the rolling instead of banking directly with ailerons. Planes that have ailerons create adverse yawing forces which work against the turn, so turning with only the rudder is probably faster (when you have provided a big rudder and good yaw/roll coupling), View the website for an explanation, or, better yet, fly a two axis RC (radio control unmanned hobby model) plane and have fun with that!
want one of these but with a four stroke motor
There are four stroke paramotor engines, no problem, you can buy one, they are rare but well appreciated. Long range paramotor fliers like the fuel economy and reliablilty of the four stroke. Reliability comes from good lubrication (having an oil and cooling system) and fuel economy comes from not losing unburned fuel into the exhaust (having valves).The problem is that when you get around to buying one, you see a really high price for an engine that has less thrust for the weight than the more conventional two stroke.

Is there a 2 seat version ?
Is this your design ?
Nice airplane !
Ultralights are not allowed to have more than one seat under Part 103 FAA regulations. Other than that, I think a two seat Bloop could be made within the Part 103 weight requirements, but it would have to be built and flown in the Experimental category in order to carry a passenger. This means design and airframe inspections, a pilot's liscense, and special initial flight requirements. It would be a unique and fun flying plane, though.
airchairp
Thank you for that info. I may buy a J-3 cub because I want my wife to fly with me. I thought that this may be a cheaper alternative ! Looks like a lot of fun . I flew a Ryan Navion years ago but this sport is getting expensive especially for a 4 place higher performance airplane.
The Navion I flew had a 200 hp engine and it was like a truck , lol. We put in the bigger 260 hp and it made a huge difference.
Fly safe , beautiful airplane..

hey is there a way you could send a plueprint on how to build my own plane?
Have a look at the website, there is a lot of good stuff there, including the technical drawings which you can view online or download.
Me parece que es un nieto de Hermanos Wright.
they like the future wright bros
Dear Michael. I want to know how do you get the dihedral angle on bloop 2. Wings..... Without the use of King post (top strust and cables) by connecting the 4 wings to nose frame..l am studying your drawings. Please do full video on building and assembling bloop2.
A fully braced biplane is stiff and strong, with no need for any more external cables (the Bloop has plenty of cables out in the breeze already!). The biplane setup has been very practical, and it goes in the smallest hangars.
It might be nice to build a monoplane, I could see more of the ground, and I'd like to know what the good points of it are.
The Bloops are not very transportable, they operate well enough just flying from an airport, but if one is taken apart I'll try to get some pictures.
@@airchairp thanks Michael sir, but my biggest worries is that if I built my bloop2 according to drawings will my wings get the dihedral angle 6 degree (B2W18,outboard edge higher than the inboard roots edge)B2W13 and B2W8..
I wonder how much hp do we need to fly like this?
There is an entry on this topic on my Bloop Q&A Page at the website, have a look! Smaller paramotor engines than mine might be satisfying if they can still do basic things, depending on pilot weight. I once flew with an engine so wimpy that I could not turn without losing altitude, and that I considered under powered.
@@airchairp Thank you for answering my question.. I read your Q&A section.. mostly... It is a very beautiful plane... I hope I can build something like that...
I think that if you considered alternatives, you could just continue to make Bloop flying videos, post them here and make a mint on UA-cam. I'm sure I've watched them all and keep looking to see if I missed one.
There seem to be more motorized Goats than Bloops, maybe that will be the motorfloater of choice. See
m-sandlin.info/Motorgoats/Motorgoats.html

what's engine power?
25 hp, see the website for details
Thanks !
do you ever plan to somehow get the bloop to Airventure?
+The Bloop as I fly it is not very portable, but it could be hauled on a big flat trailer. It would be fine if somebody built a Bloop like motorfloater and showed it, but I don't plan on that. I can show events on my website, and I'm usually busy with new developments.
+airchairp well I've been following production since the Bloop 2, and I'm surprised that not that many people know about the bloop. I think you should submit your motorfloater to the EAA or Sporties magazines. Be cool to see more built. I've got plans standing by to wip one up. Great Job!
without ailerons?
View this Flying Flea video for how to fly without ailerons: ua-cam.com/video/aOxPd7eX8P4/v-deo.html
@@airchairp Thank. Very interesting. After all, this is how the first planes were
Como consigo los planos
Follow the link in the video caption, download the drawings for the Pig.
What's the gross and empty weight?
The empty weight was about 200 pounds the last time it was on a scale, but he version shown is not the latest. See my website for more information, it needs some updating to make the basic information on the latest version more accessible, but it's all there.
Yes, I saw that; but what's the useful load? Pilot, fuel, etc?
My body weight is 148 lbs., a full tank of fuel weighs about 16 lbs. Simplistic structural calculations were done for a 200 lb. pilot. Other pilots have flown the Bloop but they were no heavier than me, so neither lighter nor heavier loadings have been flown, and no formal limits can be established. [A commercial airplane would be supported by a structural load test and could set some limits based on that.]

Helicopters need more space to take off.
I need to see your weight and balance paperwork and your licence this is The FAA
I'll take this as humorous, and an opportunity to say this that is a (United States FAA) Part 103 ultralight, so there is no direct regulatory oversight or license involved. Weight and balance would probably not be a big issue anyway, the useful thing might be an annual inspection! I found the years going by, with my preflight inspections being my only examination of the plane, so I wondered if I might be missing something.
Funny Airchairs Anonymous?
Just two reasons stopping England enjoying this, land price & bullshit regulation. At least you are in the land of the free...for now?
