The best thing about these old machines you teach us about is that you still fly them, they don't rot on a shelf - they take to the skies where they belong, just like the day they were built. I'm as equally amazed by how well they still fly as I am by how well you fly still fly them. Fantastic.
Having been around Model Planes and helicopters for over 60 years, I was ecstatic 40 years ago to be involved with the very first twin motor electric helicopter in the world. The Ishimasha Skylark EH-1 was made in Japan and was sent to me by my very good flying friend, Julius Schnell after the fire. Here I demonstrate it with no gyro. I hope you enjoy another chapter of R/C history for those who haven't seen me fly this before. Thanks kindly!
That Skylark looks like it belongs in a museum, but it still flies very nicely. I remember you showing it to me when I was there. You may be one of a very few (if not the only!) that still owns one of these vintage machines. I love seeing old machines from the past that still run great to this day. Nice job sir. Semper Fi.
After watching your Video, I start to build my own Skylark. It´s a fantastic RC helicopter! But I put a Gyro in, it flies really good. Next project is the MFA Sport 500 - electric!
It's really nice how quiet and scale it is. I remember how my trex 450 screamed in the air and was very spastic. Now every one has their helicopters bouncing all over the place . And they look like they are from outer space. I like the old stuff. Great job sir.
A real Beauty. So awesome to show this, plans built on paper no gyro no computer anything , a piece of art. Im 50 gre up in the late 70s and 80s , no 2.4ghz and nothing like what we got now.
Thanks to Julius for the Skylark EH-1..! I enjoy seeing you fly the old stuff, it brings back momories when the Dumpmasters flew every weekend in San Juan Capistrano. Oorah!
cool video, I had the cricket no gyro 1981 never learn to fly that machine ,later I learn with the electric hummingbird and the raptors 50s ,I'm a subscriber I love this channel.
That's really good! I bet it was the bees knees in the 70s. It flies well even for today's standards. It sure serves its purpose. The older stuff is always cool 😎
Wow great heli Dave....amazing how you fly it so well.....always a pleasure to watch your vids even thow I am out of the flying hobby now for 9 years.....take care JIm (manchester u.k)
I think the reason for such low noise comes down to current regulation. On EH 1 the motors are controlled via linear voltage regulation. That has minimal noise plus the motors are not hidden under canopy so noise is not amplified Today's controllers (brushed) use pwm so we are literally turning motor on and off 100khz (average brushed esc) and brushless by nature need to work with pwm and currently the best way to make brushless motor silent is to reduce pwm clipping but then motor is weaker and not as efficient. Also i personally tried flying gyroless helicopter and it flies great in foward flight but it brings cold sweat when you try to hover it
The real noise comes from the coils singing like speakers with brushless motors, not like quiet brushed. (Like I said in the video) those beeps you hear are the coils when you arm the motor. They sing rapidly at high speed, hence the constant noise. It's very rapid beeping, since each coil is fired one by one like a linear accelerator. The no gyro flying is why I pinch my throttle sticks. Cant afford to drop it. LOL Thanks.
@@NightFlyyer even epoxy coated coils make noise but the source of noise are not the coils It's the rotor As coils get triggers they produce force on the rotor but when the magnet gets over the energized coil the force disappears and that pulsing causes rotor to have that specific sound You can even hear it in the induction motor when it's direct line started all of the sound comes from rotor phase stepping when loaded
@@NightFlyyer There are if you're using an electronic speed controller, which would be what Black Turbine means by "today's controllers". Your theory that a brushless motor should be noisier because coils are being switched off and on doesn't really hold up, I mean the coils in a brushed motor are also being switched, just not digitally. Humans don't hear electromagnetic radiation, we hear by air waves. The beeps you hear when arming are intentionally done at human-audible frequencies, and mostly come from the physical movement of the motor. Try removing the rotor from a brushless outrunner and see how loud the arming beeps are. I believe they also reverse the polarity/direction for those beeps as well, to ensure the motor will not actually start rotating, and to make the bell vibrate more back and forward on the spot so to speak, instead of just getting pressed up against the natural 'detent' of the magnets in one direction which would soften the noise. I don't know much about CP helis but I suspect the rubber band drive for the tail rotor might have something to do with how quiet this one is...
@@iforce2d I disagree and have much experience with the digital motors since they were first invented. Tail rotor is typically quiet in all belt drive helis, and I have lots of experience with them. The digital pulse from the ESC pulses only 1 coil in the motor during arming, so you can hear it. It also tries to turn the motor slightly and I have seen that happen lots of times. 3 beeps will move the rotor slightly with each beep. When it is running, the motor is getting beeping all the time. Its a fact that brushless motors are more noisy than brushed.
great stuff Dave, so nice to see that baby flying what a honey, but flying so close to that graveyard might effect your radio control eh? to many "dead spots" haha, hi from New Zealand >)
Wow very informative dave! I always thought the sound was from the straight cut gears meshing as it ran. Never knew it was the brushless motors themselves. I guess I thought that because im a car guy and transmissions with straight cut gears sing pretty loud compared to helical cut gears.
Thanks much. Yep the rotating part of the motor is like a bell. Your right about the gears, but this one is quite quiet for sure as you heard. Thanks again and keep flying....or driving!
There are no weights on this flybar, just the wood paddles. Weights usually help with dampening the cyclic control and to balance the heli even further than balancing just the blades.
those batteries looked like they were bulging pretty bad. Maybe it was just the camera. You need to get rid of those asap if they are bulging like that.
Yes it is a bit puffed after that first flight when it went dead. I've all ready cut the connectors off and have it in the metal case to take to the Hazardous waste dump with a few others. Thanks.
The Ishimasa EH1 is still a beautiful vintage heli by today's standards. It deserves some justice with a Bell47 boom upgrade! Tail rotor shaft & gearbox; no belt. Keep the rheostat/servo speed control combo. And the servo that slides the rheostat, why not have it double as a tail rotor pitch control? More trottle, more tail rotor pitch needed; right? The goal will be to turn this heli into a flying mechanical masterpiece.
I already have many helicopters that have all that, so there is no way I would modify this antique vintage helicopter. It is already a flying masterpiece and is worth quite a bit of money the way it is. If I change it, it will be worthless. Thanks.
I bet you and I have met way back in the early 90’s? I learned from Ray Hosteler, and bought most of my helix in Costa Mesa from a guy that had a Ferrari repair shop and a small heli shop n the back. I think his name was Theo? Flew lots at mile square
We may have. I know knew Ray for sure. He was trying to make big engines, too as I recall. I was president of the Sky Nauts RC club at the time. We flew at Robinson Ranch up in the hills, and later on I became President of the Capistrano Aero Dumpers, where we flew in San Juan Capistrano out on the Ortega Highway. Nice to hear from you. I might have met Theo too, as I was the distributor for Klasse. Thanks and happy flying.
Yes I do vaguely remember, I owned and flew a TSK KIASER.? Kalt Baron Alpha2, XCELL 60 Custom, Hirobo Shuttles from the XX to the Shuttle Gold I’ve owned them all at one point. One oh the most fun helis I can remember having was a Kyosho CONCEPT ZEAL, IT WAS AWESOME! Well my collection was about 20+ strong, but in 1994 someone broke into my shop and cleaned house...I was devastated and quit flying for 8 years.. Ironically I ended up becoming a UAV Pilot since 06, and now I just moved back to Cali as I took a job flying commercial drones for a supporting utilities company, so everyday I get to fly a 30,000 dollar quad copter all over the greater Los Angeles area doing inspections. Please keep up these vids, I absolutely love to see all of your toys... Oh yeah, I also had a Gorman Cobra and a Dieter Schlutler robe?
@@Mu2driver Great to hear your story and success now. I lost over 100 planes, quads and everything I own, in that huge fire we had on 911, 2016, so can relate to your loss. Most of my new stuff was donated to me which needed restoring, including this heli, thanks to my wonderful subscribers. Yes and Ray worked at Condor Hobbies.
I am sorry to hear of your loss, it’s such a cool hobby, and all of us have had the pleasure to watch it grow throughout the years. By chance did you know Brian Suarez? He was heavily into Helis and hung around Costa Mesa? Anyways keep them vids going... Correct me if I’m wrong, wasn’t TSK helis Built like a Swiss watch? I sure wish I could get my hands on one...
Haha. Yeah, before Gyros, we didn't know how good they were and just dealt with it. Its hard to go back after flying a gyro, as I was reminded with this flight. Thanks Garry.
I noticed you're using a lot of puffed lipos. This is a bad idea as the lipo is puffed due to internal damage. It is basically telling you it's going to fail, possibly catastrophically. Continuing to use and charge lipos in this condition is dangerous honestly where lipos get their bad reputation. I suggest retiring any puffed lipos and disposing of safely.
Your speaking to the choir. I have replaced hundreds of my batteries. I also have to take them to a special facility to dispose of them. All of them slightly puff eventually and that is when I replace them. They look worse in the videos than they are. I have made many videos on the subject including blowing them up. Thanks for the suggestion.
@@NightFlyyer ah. Gotcha. Sorry to be presumptuous. I just go to the field and see people flying packs that look like balloons then talking about how dangerous lipos are. Kind of irks me:/
It’s so cool that you take them out and fly them. I really liked the sound of this model too.
Thanks so very kindly. I love the sound too.

Yes. It’s like they say. If you don’t use it you will lose it. Thanks for the kind words.
I think a lot of them flying well is who is flying them :). NightFlyyer is good on the sticks!
@@mssippijim Thanks James!
Pristine after all those years...smooth, quiet flight...no gyro, just pure flying skills and she's a beauty. Those gears look solid. Thanks for this👍
Thanks very kindly for your comments. I appreciate them.

So cool. And no collective pitch or gyro.. Your the man flying that so smooth.
Thanks very kindly. I appreciate your comments.
Incredibly quiet! Nice vid, as always.
Thanks very much!
Thats surprisingly quiet, it's in great shape and with higher energy density batteries of today will be ready to show how well it was designed.
Yes, it flies much better on the lipo than that big NiCad. Thanks Luis!
Someone should start making remake kit of this beautiful model heli.
Yes, I'd like that. Thanks.
Brilliant, thank you.
Thanks a lot, Chris!

Thanks Dave
Thanks to you too Shayne!
That was very awesome to see Dave especially how a simple 3s lipo flew that baby like a champ!
Yes. You should see how well it does on a 4s! Thanks.
4s I would like to see in the future someday Dave?
What a fine machine - pure gold. Reminds me of the Bell 47G .. cant imagine flying without a gyro. Thanks for showing us.
I think because it does look like the old Bell 47G, is one of the reasons I like it too. I always liked MASH because of the helis. Thanks kindly.
Thanks for an informative and enjoyable video Mr Herbert.
Thanks very kindly. I appreciate that.
Thanks to Julius for the Skylark EH-1..! I enjoy seeing you fly the old stuff, it brings back momories when the Dumpmasters flew every weekend in San Juan Capistrano. Oorah!
Thanks a lot, Bud. You were there for those great days and nights, and I'm sure you remember Cliff and his shop in Costa Mesa. Semper Fi!
Thanks Dave for showing us this classic piece of RC. The closest thing I had to this was a Ikarus jet ranger.
Yes those were around a while too. Thanks kindly.
What an amazing older machine. Wow.
I agree and really love it. Thanks much.
cool video, I had the cricket no gyro 1981 never learn to fly that machine ,later I learn with the electric hummingbird and the raptors 50s ,I'm a subscriber I love this channel.
Ah, another no gyro flyer! Great to hear and I loved my Hummingbirds too. Thanks kindly for commenting and being a subscriber Benito!
No ESC? Wow, what a beauty. I can't imagine trying to fly that without a gyro.
It also had no bec so radio was originally powered by separate 4.8v Nicad. Thanks very much.
NightFlyyer remember those from my old nitro planes.
That's really good! I bet it was the bees knees in the 70s. It flies well even for today's standards. It sure serves its purpose. The older stuff is always cool 😎

Are the weights on the flybar manually calibrated to get a stable hover?
There are no weights on this flybar, just the wood paddles. Weights usually help with dampening the cyclic control and to balance the heli even further than balancing just the blades.
Low head speed also makes for a quiet flight.
True, but the motors are still spinning pretty fast.
Sir, what should be the length of the flybar when compared to the rotor diameter.
The rotor diameter on this is 40" and the flybar diameter is 17", but newer helis with flybars can be shorter.
I think I am going to put the brushed Kyosho motor back in the helicopter after hearing this one fly . I dont like the singing sound at all .
When the Japanese were pioneers with electronics.
So true. Thanks.
I just love these vintage helicopters. Just wondering Dave if you have any idea of the head speed?
Head speed is mentioned in the manual at 1250. Thanks much.
Dave being fixed pitch how does it handle a windy day?
Well it wasn't totally calm when I flew it, but it always handled the winds very well to me.
those batteries looked like they were bulging pretty bad. Maybe it was just the camera. You need to get rid of those asap if they are bulging like that.

We could never get one of these to fly with an on-board nicad. It was fine with an unbilical to a car battery. It should be OK with modern lipos.
Never had that problem but the lipo and a bec made it lighter and easier to fly as you saw. If you had one did you buy it from me or Cliff.
