One of Dale's posts on rcgroups. As a first report I will summarize what I think I achieved by going to Oshkosh with the worlds first electric seaplane.
First, I know that I have inspired a lot of people as I think that I have shown an electric aircraft is practical now, with today's technology.
In flying a total of 10 flights, totaling 4.5 hours in the air at Oshkosh, I believe that I flew over ten times longer than any other electric aircraft at Oshkosh this year.
Even though I never flew in front of the main crowds, I was still swamped after my flights by the relatively few people that made their way down to the ultralight runway early in the morning or just before dark when I had my time to fly in the ultralight area.
Each of my 1/2 hr flights was in the same time-slot as the powered parachutes. I chose these slots because the powered parachutes had a tight flyby circuit. Had I flown in the regular ultralight slot, I would not have been seen but once every ten minutes due to the size of the circuit they were required to fly. As it was, I was able to fly down the ultralight runway every 2 minutes or so at between 100 and 300 feet high. I really must say thanks again to the parachute guys for letting me join them.
In each of my 1/2 hr flights I was able to show both gliding and single engine performance of the amphib Lazair by flying down the ultralight runway with the motors on 'idle' (read that as 'off'), then with one engine off and the other at full power and vice versa for another pass.
Carmen and I spent most of each day sitting at the airplane answering questions and we enjoyed every minute of it. Untold numbers of Lazair owners came by and swapped their stories with us.
Secondly I believe that there will be a number of people that will take action and build that electric aircraft project they have had in their minds eye. In fact, I have come up with a new t-shirt motto that I think is appropriate for myself and all those who choose to follow in my footsteps --- We dream it.... then we do it!
And lastly I believe that the publicity of my Oshkosh flying will keep inspiring future dreamers to join the club.
More soon,
Dale
P.S. The video referenced in Post #298 above is now 3rd on the list of the Top Ten Airventure Videos of this year, just behind George Lucas's Red Tails Trailer and ahead of Bob Hoover-Rockstar .... WOW
This is almost 10 years old and still the best electric ultralight on UA-cam. Why?
His design logic is really sound. Narrow mono hull. High wing. High aspect ratio with winglets. Puller props give clearance for a boom tail and inverted V stabiliser. All are low drag innovations.
On Wheels one hour and 15 minutes of flying time that is fantastic we need more like that
Very cool! Adding a hydrofoil at the bottom might make the takeoff much easier
O.k, but HOW FAR is the RANGE on this thing, AND how long does it take to recharge, whereas a GAS powered plane can travel quite a long way, AND be refueled in a minute, or two. 🤔
What a beautiful wing and a perfect configuration....I salute you for your accomplishment

Watching this in 2023, it feels quite impressive even by present standards - exciting to see electric aircraft making progress. But this was from nearly 12 years ago - truly revolutionary then, a very clear retort to those who think electric aircraft would never be feasible. Now 12 years later Harbor Air has a flying prototype electric conversion DHC-2 Beaver on floats, with plans to convert their entire fleet to electric and use them in commercial service. And more recent electric Lazair videos show that the concept has advanced quite a bit - now with four motors it leaps off the water almost absurdly fast.
I was sailing on Keuka when you flew over me a few years back! Totally Awesome! My first ride in a Lazaar was in Michigan, over the lake in 1981. Love them!
I miss mine as well. 2 20 hp JPX OPOSING TWIN. Two seater on floats. Incredible. Nice work.
Outstanding work Dale. Thanks for once again being a pioneer in flight. I love flying my Lazair and thought years ago how great it would be to have clean, quiet, smooth electric powerplants for power. That is so amazing to see. Please post some more video when you can so we can experience this some more.
Thank you for your hard work.
Thanks for posting this video. Congratulations on this aircraft flying so well on batteries & electric motors. You are part of a significant change in recreational flying, and have done a great job of leading the way. I even appreciate the inverted "V" tail, which induces naturally helpful roll when you turn. May you enjoy flying forever.
Geez I miss my Lazair. They are beautiful machines and so easy to fly.
Two 10 kw Turnigy CA120-70 motors with 32-12 props reconfigured to WYE terminations.
Two JetiSpin OPTO 300 controllers.
96 pieces of Zippy 5000 mah cells arranged in 6 packs of 16s4p each.
Six of FMAdirect PL8 v2 chargers, each one running off two 12v 900 watt Dell Poweredge 6650 power supplies wired in series to get 1800w at 24v.
You make the future of air exciting...
Those little props have got some balls. As soon as he stepped on the pedal, the plane responded swiftly.
The advances in electronics technology and what batteries can hold.
Super...
Yes, it is that quiet and most of the noise is from the propeller and the air it moves.
The noise element is fascinating . The lack of it. If you had to think , how would it be possible to make even quiter .?
Fantastic bit of gear. Totally impressed.
If I had this craft I might consider a small electric motor for a prop in the water...for takeoff assist perhaps. Or a PTO system?
That is just incredible! Soaring this bird must be greatly satisfying. This is the most realistic example of electric flight so far given the current crop of Li-po / Li-on cells available. I also can't believe you did this with Hobby King outrunners...awesome and inexpensive! I'm laughing and crying with joy at the same time. GREAT JOB!
Fantastic. There is no other word for this. I love it.
All the dreams that I could fly can come true if I can get a hold of this
Nice design and performance!
would be so cool to see how 2020 technology might do to make this even more viable. Think about what cutting edge PV on the wings would do to the battery endurance.
Hi Don, very cool, just like a large version of my electric planes. I am curious why you did not counter rotate the motors to avoid torque issues?
Fantastic! Very nicely done!
Absolutely fantastic. the world is a better place for that plane existing. I just wish somebody would solve the battery problem. The world needs better batteries for everything all the way up to electric planes and cars. efficient and light (and cheap) storage of electricity is paramount to the successful adoption of these vehicles.
Great work!
You are absolutely right. Battery technology is the only thing holding electric vehicles back.. I hate to don my foil cap, but I don't wonder if perhaps big oil hasn't been keeping some battery breakthroughs from us. Buying out any scientists that came up with something revolutionary, then locking those great ideas up!!
hi bliglum whether you are right or wrong about battery patent hoarding, I certainly wouldn't disagree with you. Your probably correct. Patent hoarding is indeed a huge problem in general and I think the only winners are large companys. something needs to be done about the patent system to stop it being abused.
bliglum I agree with you on certain people coming after you for promoting progress. And yes the government does conduct "Remote Neural Monitoring", and yes the President lied about domestic spying too. But yes we do need to get off dinosaur juice.
Dennis Richards battery tech is good enough for cars now and for planes you can easily do around 200km flights. But jumbojet flights around the world is not close to possible yet. With an extreme plane you might do 1000+km flights with current tech.
Oil did actually buy nimh battery rights to prevent the use in cars. That actually happened. Fortunately lithium was much better. I think it was texaco that bought ovonics who owned nimh patents and noone was allowed to make above 10Ah cells, with no explanation. Very evil and they will burn for it.
+Dennis Richards Yup! Now lets go burn some coal to get that clean electricity you talk about.
Well done. Gorgeous aircraft and electric.
Thanks for the reply, the person you are addressing is Dale Kramer.
So cool! Differential power must make water taxiing that thing a snap!
Innovation and courage. Well done.
the future is electric with small planes, already possible 1~2hr flight with todays battery technology and it keeps improving 18% yearly so it won't be long were its able to fly 3~4hrs on a charge that costs $2~4 per flight, bye by oil change and spark plugs
better electricity producktion.
tampicokid I didn't see a mention of "the environment" yet there are enviro benefits. But assuming argumentum that's the point, you're still wrong.
Industry-produced electricity can manage pollution much more efficiently than portable IC engines. Not to mention wind, solar, even hydro. Not perfect, but orders of magnitude better.
Puzzling that anyone who's into aviation wouldn't know that.
tampicokid you idiot. So if you hook these batteries up to a power bank which is fed by a windmill your premise is dead wrong. Think next time if you can
Give and take. Luckily they make brushless motors so no changing there. But I bet you pay for a few of the Lipos you may fondly be remembering the low price of an oil change.
did you designe this aircraft it looks fantastic, how long do the batterys last,
the rudder is like a stealth fighter except upside down. to yaw both control surfaces move in the same direction. turn left they go: down left and other up right. up they both go down and down. to go up they go: up and up. it accually works ok.
thinking of putting a electric motor and a Full Lotus Mono float on my Kolb Firefly. does anyone have any advice?
1800w at 24v. Use the "show more" high lite and access the tech data web site.
Brilliant TOP marks, a modern day Orville and Wilbur.
Ok. Pretty cool. I fly electric model airplanes. Are those brushless motors and Lipo batteries?
A remarkable feat of engineering !
Again...thank you to all R/C enthusiasts who have been dealing with this stuff since the 80's. They are the ultimate beta testers of everything great to come to full-scale aviation. More and more you see giant-scale R/C technology, whether electric or turbine being applied to manned flight. Those that have spent countless millions to involuntarily improve B/L motors and LiPo battery technology have made this possible. Thanks...Fly IMAA!
Capacitors are replacing batteries. Might be something to look at. Thank you, always wanted to fly.
Great! Where can I find the design of the float, because I would design it for my electric Swift.
What sound is the motor making when he is throttling? Or is it the tips going/getting supersonic very very quickly?
Thanks Dale....And congratulations....Pete...A899 IGGI
This is legitimately the coolest thing I have seen in a very long time. This is now officially on my bucket list. Would you mind sharing what materials you used for the wings and the body? Also what type of motors did you use? Batteries (I assume Li-ion but specifically which type- LiCoO2, LiFePO4, etc.)? Thanks for sharing this incredible project.
+Pedro Casultsan www.rcgroups.com/forums/showthread.php?t=1412424
got to love electrics,it adds so much while taking away all the complexity of a combustion engine.The efficiency is more than double,once battery technology catches up,watch out.
OMG you need to add solar panels on the wings and to go overboard you could add more propellers creating more power than your using, making it fly long as you can stand without food/water, did i mention it looks fun?
how many kilowatts are the motors rated at? Are they Automotive starter motors or something like that?
Brilliant brilliant brilliant! Plus that was a damn fine landing to boot! God I love innovators!
where was this? there are some guys claiming the first flight of a canadian electric airplane. they are using a trike.
@vondeliusc The technical information is very complete at the RC group website listed under the video."show more"
See the description. He says he flew 10 flights totalling 4.5 hours, meaning he has at least 27 minutes of duration from the batteries. That's no mean feat.
WoW, this is just so elegant. Very nice.
Excellent. Looked a bit touch and go at first.
Have you tried in calm conditions? Looked like the wind helped keep your 'ground'speed down (less drag)
At the end I thought it would be cool to do a long 'ground'skimming flight.
I have flown the Seair alot and it is a blast flying off floats. (seair daughtcom)
I like the uni float system and the electrics are nice too.
More vids, please and details of batts and motors.
Nine years ago ?
That's amazing!
I just saw this 2 minutes ago, is this guy great or what!
And he did it nine years ago! That's impressive
how long does it take to charge the batteries until they are peaked??
did u built the floating setup by yourself and if so how did u do it?
Cool what are the motor are you useing
Thanks for the comment from Istanbul, Turkey
With DC electricity there is a big power drop in the transmission with distance. The weight of the wire a very big factor. Thanks for watching.
you need to build a solar panel into the wings, and and make the wings wider and use a battery just for takeoff, that way you should be able to fly much longer
I flew a Lazair for years and found that the Lazair (not just mine) did not glide very well with the props not turning. Friend did a tuft test (shot video) and found pronounced airflow separation. With props at idle airflow reattached. We were thinking of putting VG's along the LE edge to correct this.
Someone flew a E powered trike in BC last week and now getting credit for the first E powered plane. Dale is Canadian and his ship was airborne long ago besides the lazair is a true airplane
It is just amazing! Really, this is something everybody should see
how long can the engines go for . ? what range?
The motor startup sounds really rough. Any idea why?
Electric motors sound like that normally from 0
What's the autonomy?
A Watt-air-plane!
Cool!
Pó
why the battery in the wings and not in the boat (stability)? And it is logical to use the wings on top of the plane of the solar cells of amorphous silicon (light weight, will not be redundant)!
What is the horse power rating on each of the motors ,I'm playing with 31 cc engines.I'm curious
Tolle Leistung, sehr umweltfreundlich.
What's the flight time for this aircraft? What kind of batteries does it use?
What is the price of this plain
Might be a silly questions, but do you need a license to fly a small plane? or a glider for example?
that was awsome. I bet you can't wait for battery technology to pack 10 times the milliamps in the same size battery. They could get lighter too. I bet you could get an extra minute or two if a boat towed you up there. I also understand the importance of solo flight.
Are these units for sale?
Hi Don, thanks so much for responding to my comment a few days ago and all the helpful technical data on the RC site - I learned so much and really appreciate it! I'm wondering now if HobbyKing offers motors that are the next sizes smaller than these CA 120-70's - I need good torque, but Dale's arrangement is about $8,000. Is there an optimum setup for half this power with batteries, controllers etc., that isn't so expensive, since my vehicle is still a prototype? Again, thank you! Dave
what lake is that because it looks very familiar to one i live at
If you sign up at the rcgroup and ask the question there you will get a better answer from many different experiences,
way to go Dale !
what kind of battery are you using it?
Great job, congratulations. I hope you can much more develope design and powerplant for future. I believe you are one of the milestones in aviation history. Thanks for your inspirations.
Есть чертежи планера?
I have a friend that builds planes. I'm thinking of making one with him, but will I need a license?
What are the electric engines in this airplane? Producer, power,...
Thanks, regards, Salut †
That's a low crosswind turn. I'm not confident of getting the wings level if I lose my engine at that altitude.
a new wonderful toy for humanity ! well done for the inventor !!
Wonderful !!! I wish you much more success.
👏👏👏👏
How much?
weight?
Wow!
So is this a 60 or a 24V system? (16 X 3.7 or 16 X 1.5 ?)
One more comment how much is the cost with wheels not pontoons
You will only find used Lazair mostly with wheels.
This is fantastic. if you want to fly and RC float plane or flying boat you would probably want a boat to recover it in any case so why not do this?
Very good. ¿Money?
@windpowergood First take off and landing of "electric" powered seaplane. Just think of the possibilities for the future, batteries charged with wind power.
Solar!
Astonishing airplane!
As fan of electric power, now I start wondering if a single-seated electric helicopter is plausible at current time.
BTW, can't wait to convert my nitro heli to brushless :)
awesome but still a cmbustion engine allows you to fly more time in expenses of noise.. plus recharging doesnt take forever..
Very Nice! This is an option I've been considering.
On the water safety,i like this
I think the tail is upside down because you risk it will hit the water on takeoff and landing.
Brilliant! really well done! I want to make one!
Nice clean design!
