I remember flying with you at the Gimli Manitoba UL meet in the early '80's. I flew my Pterodactyl there from Idaho. During the event that gave each pilot a measured amount of fuel, We climbed up to 1,000' and the pilot that landed last won, I came in second in that event, to your first, and I seem to remember you looping your bird still under power, while I was dead stick gliding down. I could have the details wrong, it's been a long time, but the looping I clearly remember! That entire trip was a blast. I fly a RANS S-7S these days.
Nice work Dale! I have always enjoyed the Lazair design. I owned one for several years and put over 800 hrs on that Series 2. Someday I will get another one.
I owned a Lazair Series II back in the day and it was the best flying plane (ultralight) I ever owned. I would imagine, with those four motors pumping air over the wings that you have a lot of induced lift just sitting there...thus when you put the power to it the plane just wants to lift right where it's sitting. I wish were still able to purchase a Lazair...sort of wish I never would have sold mine.
Wait a minute... Reverse and some asymmetric thrust to steer? Now that's a very cool set of features! I only saw that applied on the R/C planes I built here, but I never saw in a full scale aircraft! That's amazing! :D
Took about 40 years for that to be accepted. Totally agree!👍 great design Dale! A lot of people , including me have tried without success to improve it.!😊
those four motors means double redundancy, even if two failed, thanks to the extra ones and the big wings he can safely glide to a safe landing. looks good for a nice quiet sunday to survey your farm and see how everything is going on.
Just loved it! Envy your ingenuity, really nice job. Building an electric waterplane looks difficult in a flimsy kinda way at first, but just trying to imagine all the kinds of stresses on the frame involved, keeping weight “close to zero”, choosing power, controls, etc. More than just building going on. Great work! I believe the Lord, being the ultimate creator of all time, whenever he sees man build something like this flying, he smiles… in his image 👍
This is incredible! You’ve made your dream come true! Congratulations! I always liked float planes! I’m playing with large scale RC and flying airliners for a living. Never was brave enough to combine RC components with a plane you can actually sit in. You did it! Some of the planes I’ve built are close to the size of your ultralight. I don’t know how good of a swimmer are you but I would consider a sailer life jacket what blows up if it gets in the water otherwise it’s like a belt. Super light and barely there.
I remember my old Vector 600. Your Lazer is quit similar. So light !! Friend of mine use to play a lot with PP software : I told him : well, you want to be a pilot. For myself I never wanted to be a pilot but I wanted to FLY. I so I did since 1984 to 1990. 350 hours flying. (In France)
I have those same floats on my Quicksilver , I like how your plane has the inverted tail feathers it reminds me of my old friend Moulten Burnell Taylor's mini Imp ..
Great video! That must be a great experience. My father owned and flew several different airplanes. The closest to an ultralight like that was his 1948 fabric covered Stinson. He bought it in poor condition and restored it.
I wonder how much spreading the motors across the wing like that improves low speed handling. I bet if you move them further out on the wing, put winglets on, and use them for differential thrust you could really improve the yaw and pitch in Stol flight
This is so cool! Is there anywhere where you catalog the design process? Like, what made you choose 4 motors instead of 2 larger ones? I saw something like this with a single float, does 2 make it more stable? Does it handle better on the water or on the step? Is there any other changes you are looking to change?
1. Not yet other than this video description and my comment replies. 2. See video description. 3. It is just a matter of choice. 4. On step and off step are at different speeds so hard to compare. Both handle well. 5. So far no changes needed except that I am still optimizing propeller selection and building my final LazairVane design.
Very nice! Build it and they will come. Produce plans and they can build their own. Very short take off run. Nice climb. I bet that is a ton of fun at less than 300 pounds.
What an excellent design. 🤩 Impressive runtime too for an electric! If there were two cells in parallel for each motor I doubt it would double the flight time, but it would be interesting to see how much of a boost it would be.
Very impressive aircraft - shows what electrics are becoming capable of. Not that much range, but decent power and built on a budget I'm sure far smaller than any gasoline aircraft. For one or two daily "clear your head" flights off the lake this is perfect. Based on the description and what's seen in the video, this must be the most maneuverable on the water seaplane ever built. I'd probably go through a few battery cycles just playing around on the water before I'd even take off, as the water would be so much fun - once in the air it's far less unique.
Dale I have a large picture in my office that is directly behind and above my computer monitor. I purchased it at Ohare airport when I was working out of Ohare flying the EMB145. It is a picture of a China Clipper leaving San Francisco in 1935. In the background is the Golden Gate bridge under construction. It is a photograph taken by Clyde Sunderland.
Very cool! Also in that vein, the Princess Flying Boat was a remarkable "end of the era" example and I was fortunate to meet Dick Stratton its chief engineer in 1979.
Great airplane! As a sailor, those downward pointing tails are a worry to me: one hit with flotsam and they will be destroyed. Could you invert them and make them point upwards? All the rest of the surfaces and props are nicely away from the water, except for those tails.
Wow. The four motor version! Everything looks slim and trim. About four seconds to takeoff. How is the flight time? Looks like all new motors, props, and batteries I'm guessing? eLazair4. Awesome machine. Thanks for the video.
On floats I am getting about 1/2 hour flights from four 9.25 lb batteries (one inside each motor nacelle). Sorry, just short answers for now ;) All up weight with batteries and floats (no pilot) is 288 lb.
Thank you Dale! Huge fan of your work. To solar power your xcountry barnstorming, I ran some numbers. Unless I made an error, 11 lbs of solar cells, not including tab connectors, encapsulant, and backing, in a decent sun should fully charge your battery bank in 3 hours. Maybe a dawn flight, mid day charge, dusk flight. Or maybe charge one bank in the air while flying on the other. Main concern is temperature. I have seen solar cells reach 140F easily in the sun. I’m guessing the translucent tedlar does not get as hot normally. Curious how it might handle that heat, expansion, etc. I have tried 3 times to link to the spreadsheet with my calculations, but the comment then throws an error.
beautiful aircraft. Larger propellers would definitely help with propulsive efficiency, but the 4-prop arrangement is definitely an improvement over the original 2-prop design.
Very nice build and you are right to enjoy it....A little advice about building an ajustable seat to preserve your back when cruising on water.I dont think that position is confortable for it
the electric motor is ideal for aircraft. The motor runs at a constant speed without a cooling problem. This is a great trial and I hope it leads to more development
The video is fascinating not just for its content, but the way it is choreographed without narration or voices. Is it professionally produced and edited?
Yes but only if you call my wife Carmen and I professionals. She took the video with her hand held iPhone and I edited it. The cast was a little difficult to manage but the birds did somewhat cooperate. Carmen, also by the way, took the picture that appears on the Canada Post "Lazair Stamp" with her iPhone, so I guess she is more professional than I am :) I see that you too use a non-narrated clip on your website ;)
The inverted V tail seems like could be a problem in choppy water. The surfaces getting splashed and wet. Possibly handling issues in Crosswinds Etc. Why not just use a conventional tail for practicality and safety
I am not concerned about a wet tail since I fly only on fresh water lakes. But immediately after this flight of the eLazair4, I moved the floats backwards 4" and now they are now not in water when stationary. The tail is a down V tail because when yaw moment is created by the ruddervators, there is also a rolling moment created. With this inverted V tail, that rolling moment turns the airplane in the same direction as the yaw moment and with a normal V tail the rolling moment generally fights the yaw moment. This is tried and true tail design with 45 years of use on 1200 Lazairs. It is cable braced forward and I don't know of any tails removed from handling on water or land .
@@DaleCKramer okay I understand the technical aspects you describe. I did not know that it was a proven design but either way you see very few if any inverted V tails on any aircraft. I still think my concerns are warranted if you were to ever experience severe weather conditions. Very rough water and even the possibility of a semi crash landing where you actually stick the tail in the water which would not occur if you had a regular tail design it just looks unnecessary. As far as the yaw effect again seems unnecessary considering that you even have differential thrust capability with the multi-engine. Looks like one of the major goals of a water aircraft is to keep as much of the aircraft out of the water, again when you consider rough water conditions. Also though I understand you have no desire to redesign the aircraft
Ultralights should not fly in rough water. Mine will be likely LazairVaning when it gets too windy. Besides on my small lakes it never gets rough anyway, not like it did when I lived on on Lake Erie for 20 years and I still flew my seaplane Lazairs there in 4 foot wind driven swells that kept bigger seaplanes grounded. I started takeoff at the top of a swell and was into the air on the top of next swell. Land crosswind in the troughs and come off step as you weathervane to the top of the coming swell. (not a beginner maneuver ;) ) Differential thrust is not intended for yaw control during normal flight even though I will be posting videos of weird in flight differential thrust yaw maneuvers soon :) .
@@captainaxle438 I. I concur with Dale. I’ve played and enjoyed the Lazair both on land and water that conventional aircraft found uncomfortable! And in B.C. mountains! I’m now77 and still enjoy flying them!
This is very incredible and inspirational. Congratulations on achieving flight on your terms. As an American, this gives me a great sense of pride. Just to think of a neighbor on a quiet lake somewhere chasing their dream and having the opportunity to build something like this and fly. Only in USA.
There's 2 brothers that built a flying bath tub in Germany....Your countries collapsing right now and you think the US is the only place this happens...2023 the year China and Russia collapse the US rofl. Good riddance to the warmonger country of the world! Your banks have already started to collapse, your governments been printing money for decades causing all the worlds inflation..
AWESOME STOL!! =D Though... sorry to nit-pic, but had to point out a spelling mistake. =( at 6:19 it's not spelled "need bumpers" it's actually spelled "need patience". Not trying to be a grammar nazi, it's a common spelling mistake. I myself have made the exact same grammatical error, comes from chillin' with today's youth. =P Hope you have a super awesome day ^_^
WOW! One of most grate plane which I see in my life, fly in silent this is very cool. Just a few questions as engineer to engineer. 1 Why tail arrange doun, this is modern desine, but app side more safety on waer side. 2 Dont You think that external engines (P and S side) must located more wide (apr. +50 sm from middel line). 3 Have you 3-blade propeller. 4 Have you any design withs additional weels for landing? Best regards, creative and inspiration.
Thanks, I will try to answer your questions but I think some grammar and meaning was lost when they we translated. 1. Tail is down because when yaw moment is created by the ruddervators, there is also a rolling moment created. With this inverted V tail, that rolling moment turns the airplane in the same direction as the yaw moment and with a normal V tail the rolling moment generally fights the yaw moment. This is tried and true tail design with 45 years of use on 1200 Lazairs. It is cable braced forward and I don't know of any tails removed from handling on water or land . 2. The two main factors in spanwise motor locations were to keep the pilot outside of propwash and enough distance between the propellers to minimize noise from interactions between the props. 3. No, but they are generally less efficient than properly optimized 2 blade props. 4. My eLazair v2012 was setup with wheels. Here is its playlist: ua-cam.com/play/PLBrDXuQT1POsFSZtX7Fp5zZefYHRXTiEx.html
Thanks but for me, the risk of random motor turning falls into my acceptable category during the battery plug in/out stage due to the inherent non-random and complicated process of convincing electrons to rotate brushless motors . If the motors were brushed motors I would not have done it this way. On an ultralight aircraft, every ounce of weight is worth saving and I saved a lot of ounces doing the system this way.
Wow, so cool. Always loved the look of Lazair, and here she is again, beautiful as ever, and all electric. Good to see!

Hey mate , that's an awesome recollection man love how time gives up it's good stories 🙏👍
I wish there were plans I could purchase for this ultralight. It was a superb design and I love its flight characteristics.
My hat's off to you. Your aircraft looks graceful and well proportioned. The anhedral stab is a work of art. The performance is simply breathtaking.
Most impressive. Light weight and just enough speed for a nice relaxing flight above the lake.
Бесподобно и восхитительно. Особенно удачно реализовали задний ход и разворот.
Класс!
Всех благ.
Amazing, would not believe that you could break sucktion and get in air so quickly. Great job!
I think with those four motors pumping lots of air over the wings...you probably have a lot of induced lift with just the motors running.
Nice work Dale! I have always enjoyed the Lazair design. I owned one for several years and put over 800 hrs on that Series 2. Someday I will get another one.
Non-flier here, just some bloke looking at UA-cam and stumbled on this video. That looks brilliant, well done. 👍🏽👍🏽👍🏽

That is absolutely the coolest ultralight I've ever seen that thing jumped out of the water
I still have a brochure I picked up at a fly in from 50 years ago. Always loved the design.
just nothing short of amazing

3. No, but they are generally less efficient than properly optimized 2 blade props.
4. My eLazair v2012 was setup with wheels. Here is its playlist: ua-cam.com/play/PLBrDXuQT1POsFSZtX7Fp5zZefYHRXTiEx.html
@@DaleCKramer Thanks a lot, its clear well
He forgot to check for water in the fuel during his pre-flight.
😆
Nice project !
Brilliant!
Nice job!
Круто, и лихо взлетел!
I'm impressed.
Thats awesome!!!
Well done
Beautiful!
Really cool. Having your hands near the props to connect the motors/batteries probably needs some rethought
Thanks but for me, the risk of random motor turning falls into my acceptable category during the battery plug in/out stage due to the inherent non-random and complicated process of convincing electrons to rotate brushless motors . If the motors were brushed motors I would not have done it this way. On an ultralight aircraft, every ounce of weight is worth saving and I saved a lot of ounces doing the system this way.
