Single Rotor Bladed E-Sky 900 Heli + Mild 3D STUNTS of Blade 400 & Hyperfly
*** Please read before Commenting*** Vaguely tried a long time ago before today’s vast technology, I have proven the Single Blade Rotor head concept to myself using today’s modern machines. Why not before? Well, people said the concept is so ridiculous they would never consider doing it on big helis or models, because it simply couldn’t work and would be a waste of time. Well, my past single blade rotor video experiments led me to this next step, a bigger, heavier helicopter. I used my E-Sky 900 for this next experiment and is not a waste of time to me. It is science, physics, and fun.
Theory: With one blade, there is not as much blade turbulence, thus it’s quite sufficient, uses less power, has longer run times, and is quieter in cruise.
My physics friends tell me that as long as the counter weight is on, there would be no extra stress on the bearings. Bearings get changed at regular maintenance intervals on helis, so this is no problem. If my bearings start wobbling, I will tell you and change them.
With today’s materials and technology, almost anything is possible.
CCPM helis are difficult for most folks to learn to be good on in the first place, let alone for novices to be able to experiment like this.
So for those “Armchair Pilots” with negative opinions, I suggest you make your own heli, learn to fly it good enough to experiment, then put one blade on it to prove it for yourself before making opinions that it won’t work, is unsafe or ridiculous.,etc, etc.
Bumble bees aren’t supposed to be able to fly on paper blueprints either (due to unusual design and balance), but they do….backwards even! So never say never.
The point is that lots of ideas may work if your not afraid to try them. That’s why I think a lot of our stuff is manufactured overseas, and not here is because people are always so skeptical here, afraid to get hurt, etc, etc.
My idea sounded ridiculous to everyone I told I was going to try it to, but after explaining the theory, and with visual proof, they are now believers.
Lot’s of people are afraid to try anything outside the box. But not me.
I have proven this concept to myself. Maybe it’s not good for big helis, but it’s sufficient for me as my helis do all I want or need them to do at my age.
I am sure that I have proven enough that at least small toys, models, and flying machines will become the next step to use the single blades on, as it proves stable, uses less power, and would be cheaper to make.
I like my setups so much, I am leaving my Hyperfly, Blade, and ES-900 just like they are now. It is way easier to fly, believe it or not and I have spare blades for all. Haha.
Stay tuned for more experiments like this and thanks kindly for all your support.

Will the Hyperfly NOTAR Hover?
People say manufacturers stole my idea for ETRMS and this NOTAR. Listen, It was never stolen! I simply was messing with inventing and doing untried stuff back when RC was new. I never tried to sell the idea, just show them off, so I sent articles and pictures and vids to the magazines and manufacturers. I just wanted to show what I could do and they could print it, which they did. I know all the people who used the ideas, especially Aki Suzuki (owner of Kyosho) who paid me very well for 8 years for this Hyperfly Idea. Many people said it could not hover or even fly at all for that matter. Mode I Radios made it tough for USA pilots who can’t fly airplanes in Mode I either. Once Great Planes began selling them with a radio, I tried to not allow them to sell it with a Mode I radio,but it was out of my hands by then and Futaba had a ton of left over Mode 1 radios, and made the deal. I was disappointed in that. But it really sold well overseas, where they fly mode I. Because this machine was new, and unconventional, it was beyond most Mode II fliers flying capability who had no understanding of basic helicopter theory and aerodynamics. Here I show exactly what it could do. (And of course in the right hands), they were proven wrong, as I demonstrate the extremes in this video. (some people can’t drive you know, and if you dare to learn something new, with practice, you can master anything, as many of us could really fly the Hyperfly great. But most not, and it is still the same …
