I don't need no "stinking" tail rotors on my ELECTRIC heli.
Right from the Websters dictionary!
1 he·li·cop·ter
Pronunciation:
\ˈhe-lə-ˌkäp-tər, ˈhē-\
Function:noun
Etymology:
French hélicoptère, from Greek heliko- + pteron wing — more at feather
Date: 1887
"An aircraft whose lift is derived from the aerodynamic forces acting on one or more powered rotors turning about substantially vertical axes".
It says nothing about being invented to lift straight up. It was a STOL machine at first, and hovering became a bonus!
It needs no tail rotor to be called a helicopter. Neither does a CH46 Chinnook or the Russian full size coaxial helicopter.
It was built for fun and to see if it would work. It did and I got paid for it!
Who cares what I call it!!??
I am amazed that some of you worry about minor things like this.
Most who put it down, couldn't fly it anyway.
Those same people would crash their model airplanes too and blame the manufacturer.
Real planes cannot take crashes either! Why the heck do you think a model airplane or helicopter can take the same abuse.
And those of you who try to learn on your own because you don't want to ask for help, I wonder if you would jump into a real heli or plane and think you could fly it without lessons!
So for all the so-called "purists" that like to make fun of my title, (which has nothing to do with my ingenuity in this machine) and argue it is not a helicopter),I present this definition right directly quoted from the Websters dictionary!
I'M USING A WEATHERVANE EFFECT PROVE A POINT!
EXPLODING Helicopters for movies in the 70's gave me the idea, when I found I could land helicopters like airplanes when the tail rotors were blown off.
This video shows how we pioneered the equipment by being persistent.
So now, is your speed control burned out? Tail rotor broken?
You don't need one to have some fun with an old electric heli.
(Oh, and by the way, there are no real full size electric helicopters)!
In this video, I take you through some of my personal history of Model Notars 1978) and electric Tail Rotor motors. (1979)
On my first Electric Tail Rotor MOTOR,(ETRM) Victor Kmosek of Victor Engineering made me a special speed control to run the 2 540 can motors and the tail rotor #370 motor.
There were no electric mixers for those, so it was a handful and the speed controllers got red hot and burned out alot, even with big heatsinks.
Today we use pulse code, so they are very efficient.
Testing was hard too, since 1100 mah nicad batteries were about as big as you could get.
There were no NiMh or LiPo batteries then, thus limiting flight times a lot.
And on top of that, it was FUN to be able to
be able to FLY something, the NAYSAYERS said couldn't.
Kyosho (biggest Model Manufacturer in Japan) thought it was a fabulous Idea, manufactured it and it was the Largest Selling model in their history.
It has become part of science experiments, featured in Aviation and Space Technology, and on Display at the San Diego Aerospace museum, in the AMA's History of Model Aviation display.
I am proud to have proven that if you never give up, you will succeed.
Thanks for watching and happy flying.

perhaps you read the comment, but did not understand it?????? I told nightflyer that he was RIGHT in answering the guy the way he did. I liked his invention and was challenging the HATERS (not him) to come up with something better. It is really easy to criticize but really hard to actually DO something. Are you kidding me I like that helicopter with no tail rotor.
At least during the …
At least during the whole string of posts between myself and Nightflyyer, there was no insults or demeaning statements. You are obviuosly not capable of this, I am sorry for you. What has this dumbass done, 20 years in the military maintaining real aircraft, I have been an A & P IA for the last 10 years, I have held a pilots licence for the last 22 years, what about you??
I did read the info …
I did read the info to the right. I'm not trying to show how smart I am, I made a comment and you were unable to understand the point I was making, you still don't understand, I'm over it.
Maybe some people …
Maybe some people might actually read the description to the right of the video too before trying to show how "smart" they are.
The dictionary confirms that a helicopter does not need to have a tailrotor to be called a helicopter, and the original helicopter was invented as a STOL, not a VTOL.
CH46 twin rotor Chinnook helis will fly fine without a tail rotor and so does the Russian Ka-50 attack coaxial helicopter.
Names have nothing to do with this video either! Thanks for the comment.
well said …
well said nightflyyer, what has that dumbass done???? Crap! that's what .. so STFU
Well again I …
Well again I invented a flying machine that was fun and needed way less parts as you say. IT was revolutionary at the time, featured in Aviation & Space Technology mag, is in use today in other RPVs by the Navy, and on Display at the San Diego aerospace museum. IT was cheaper too, because it only used 2 channels and no complicated costly tail rotor. It was all about making SOMETHING fly, as a model when electric helis were marginal. Sorry it doesnt match or live up to what you think you want.
What it boils down …
What it boils down to for me is this, the only reason a helicopter was invented, and the only reason helicopters are still manufactured are because they can hover and land/take off vertically. Helicopters cost many times more than a fixed wing aircraft and are very sophisticated and costly to fly due to the much higher maint requirments. The only reason to spend so much more on these is for one reason. Hover and VTOL.
Thanks kindly. Our …
Thanks kindly. Our CH 46 helis would hover in less wind that that as I found out in the 33 years I spent in USMC aviation field. It also has no tail rotor. Here is the Websters dictionary description for a Helicopter. It says nothing about tail rotors or vertical take off.
1he·li·cop·ter : an aircraft whose lift is derived from the aerodynamic forces acting on one or more powered rotors turning about substantially vertical axes.
I checked out your …
I checked out your "will the Hyperfly hover" and you state that it will hover if there is a 5 knot wind, well I have a 4 ton Kingair that will hover if the wind is 105 knots. I'm not knocking your idea that you followed through with. I don't think you are getting my original point. Ah well, it dosen't matter. Congrats on your models and videos.
It will hover! Dont …
It will hover! Dont know what you guys are getting at. The point is, if you have an idea, follow through with it. I did, and got paid for my idea too! I want all to persue their ideas. Forget what it is called, because that is unimportant in the big picture as its now all 20 yr old stuff. See my video, "Will the Hyperfly hover"? And as you see, I can make it do everything, includng hover. It loops too. When the motor is off, theres no torque to worry about, so it auto rotates down fine.
You say I have " …
You say I have "missed your point", I wasn't aware you were trying to make a point. I wasn't knocking your design, good for you, it does what YOU intended it to do. I was just saying that IMHO, the most important part of a helicopter is it's ability to hover. Your model is like having a submarine that can only operate on the surface.
Thanks very much. I …
Thanks very much. I am glad you approve.
Wow awesome …
Wow awesome invention, keep them coming! It reminds me of that contraption that leonardo DaVinci did without a tail rotor, but this one works?! lol.
Microflite??? I …
Microflite??? I have given you every opportunity to apologize to us. Unfortunately, your ignorance and arrogance has betrayed you. You don't need us, and we don't need you. Your comments have nothing to do with the design of this particular model. Goodbye.

You also missed the …
You also missed the point. This machine was not designed to Hover. I got paid well for inventing it to fly forward!! I have plenty of helicopters that have tail rotors. This designed for fun and it worked on only 2 channels, way better than havocs, reflexes and coaxials.
Ohh you're so funny …
Ohh you're so funny mr microlabrat. So please enlighten us all and tell us what the title should be. If you look up the definition on 'helicopter', it mentions nothing about a tail rotor to stabilize the tail, but rather 'an aircraft without wings that obtains its lift from the rotation of overhead blades'.
You may not need …
You may not need any "stinking" tail rotor on your helicopter, but if you wish to use the very thing that makes a helicopter special, i.e. VTOL and hovering, then you do indeed need a tail rotor.
Yes I agree, I wish …
Yes I agree, I wish I had used a better
choice of words but I find the title
very misleading.
Winston, Its pretty …
Winston, Its pretty clear you have the
intelligence of a baseball. Not to mention
a foul mouth that needs washing out with
soap. Perhaps your family had very close
relations with close relations? I think its
likely.
The title of this thread is an insullt to
the original designers of helicopters.
Yes you do need a very clean smelling
tail rotor for a helicopter to be a
helicopter.
And Wonston, please keep away from
family gatherings eh
Look on the bright …
Look on the bright side, Dave. Out of the 90,000+ people that have watched this video, there's only one asshole who doesn't like the title. That's not a bad track record if you ask me. (You can delete this comment if you'd like. Wouldn't hurt my feelers none.)
Your very …
Your very disrespectful. You (@microflite) said:
"Even 20 yrs ago removing the tail
rotor is not a revolutionary invention by
any standards, its simple, well known aerodynamics.
So dave is first to prove it in a model when helis were new and not super like today, and you act like "oh well" I could have done that! Kyoshoos like it enough, to buy the idea from him, so how come they didnt just do it themselves? Shame on you again.
I think you do.
…
I think you do.
And the fact that I don't need a tail rotor doesn't mean YOU do!
And you obviously missed the "fun" point too. It was fun to fly and still is fun, if you know how.
I didn't make this …
I didn't make this machine to hover!
Your negative comments discourage people from trying something new because you argue success! You are also insulting Kyoshos, Hitec's, The Navy, The San Diego Aerospace Museum and my intelligence. The similar RPVs the Navy is using, catapults them off the ship. As long as they're moving,can carry lots of weight,etc. They didn't think this was a bad idea, as lots less parts.
You missed the point. There are needs for everyone, even if it is just for fun!
Its pretty easy …
Its pretty easy answer, as it doesn't need one to fly!
Also FUN to fly, LOOKs like a heli. Only 2
ch to fly. Cheap to make,those days.
There are no real Electric Helicopters! This is a model. Anybody who can design a new model, these days I commend, not putting down for showing ingenuity.
Airhogs makes notars. Guess you think those are ridiculous too! Russians make a real coaxial helicopter notar, but called a heli. You obviously didnt read Video description or watched the video responses.
