- So it's confirmed! We can clearly see, that the concept of shifting propeller is confirmed and we can start the durability test.
Next video will be about release date?
Join us on our way to make the best paramotor propeller , that improve fuel economy by 33%! The SCOUT Variomatic propeller is the first in-flight adjustable propeller for paramotors in the world. And it is very different from the systems used on ultralight airplanes or bigger aircrafts. Because paramotors are so special. We truly believe paramotors are the best aircrafts in the air and with innovation they become better again.

Keep the white blades, they look great & everybody can see from a distance if someone uses your prop - that`s great marketing!:)
We love what your doing here and appreciate the effort your going to.
Thank you for taking us along 😊 what a wonderful Sunday gift
What an amazing achievement and potential game changer for the paramotor community keep up the great work Miro!
One small step for takeoff, one giant step for paramotorists..... 👍
Innovations like this are exactly why I purchased a Scout and why I will continue to support you and the team in the future. Well done - looking forward to flying with one of these!
Much appreciated!
Your work is always very interesting and innovative. Thank you for all you do for moving paramotoring forward.
This is exciting. Could be a game changer for xc flying
I believe creating a different set of "High Altitude Springs" would allow it to downshift completely where the air is less dense. Going to be flying at high altitude? Just switch the springs and go!
Your dedication to continuous innovation is inspiring. “Props” to you and the entire team!!
Looking forward to try it one day on my Scout in NZ. I seem to use quite a lot of fuel at the moment.
Miro you are doing a great job! Looks very promising. I'm following all your work 😊
So nice work. I think thats the future. But i like it all Black haha. Greetings and stay healthy.
Spray paint...
I'm not a pilot but one of my hobbies is building electronic circuits. A spring loaded system will need constant adjustment. A solenoid is not an option because it adds too much weight.
l think a set of digitally actuated miniature gears that adjust prop pitch by rotating and latching to hold position is worth considering.
Just love your projects and your approach to improving the sport.
Genius! Thankful for visionaries like yourself and your team helping to make things better 👏🏻
It's so good to see that your variable pitch prop is working well now! When I get more airtime, I'll certainly consider buying one for my Scout Enduro.
Amazing job miro.. but how about other motors? I guess it is possible to fly with other similar stuff with just spring preload setting. Just asking this because i know alot of pilots that fly polini motors as myself. I fly 190hf and power range is very similar to moster factory r but bolt pattern is different and it has longer stroke so it has about 200rpm less witch i think it would be adjustable by spring preload not weight.
If you decide to test other motors just contact me and i can help with that..
Ps. Keep making world less boring
Did you have Tucker Gott try one out? He is a sharp dude and intuitive and honest.
Miroslav, this is brilliant! I would like to see it adapted to the Scout Pod. Perhaps a folding version of the variable pitch propeller.
With these test LEDs, you should be able to climb to 10,000 feet just prior to sunset, then check RPMs for blade shift at 10k, then 8k, 6k, etc as you descend, then land before it gets too late. You can then try that again with different springs. Sell the prop with a set of springs, color coded for various altitude ranges. Maybe even different pre-loads on different springs (set of springs and screws). Having that LED setup would make doing those tests much easier. Just make sure the air pressure isn't vastly different between tests, since that would change things as well. Or, just set altimeter to 29.92" Hg, and base the tested altitudes on that. With a few weeks of testing, you could really dial in the springs.
Hello Miro, what a great and promissing product. I hope very much, after finishing all tests and starting the serial production for the PPG the next adjustment of the variomatic prop will be for the ultralight trike family. If so, you have your firt customer, Merlin Trike BMW 1100. ;-)
PS: Just made 2 weeks ago some prop readjustmens on my fixed pro, to test new pitch and I couldn´t belive how unbelievable great effect 2,5° has on it. Since then I´m totally convinced, we as trike pilots need also a very simple robust variable pitch prop. So hurry up. ;-))))
well done with the testing and innovation so far ,as a design engineer myself i know that it will not stop" their "as new ideas get integrated into your design to improve and better where it all started from in your first propeller concept.? well done to you all.
Thank you for the fine methodic hard work you are doing to advance the art of PPG. I'll keep following you and might eventually have the pleasure of doing business with you when you go into production.
Wonderful work, I thought it would be years before seeing variable pitch propellers and yours is more a constant speed. For me and most para-motor pilots and your business, the big issue is noise. If we disturb people they complain, parks and other take-off areas are lost. If the problem gets big enough, legislation will reduce where we can fly. I have been thinking about zip-line drone's quiet propellers and wondered if two different diameter prop blades long-thin and short-broad could be used, both balanced to have the same angular momentum? If this broke the resonance of the prop blades it could be hugely quieter with very little efficiency loss. Once seeing your prop hub with the blades bolted in, I thought that would be perfect to test the theory. Quiet flying will keep our flying freedom. I would love to see you try this idea.
Such a great feeling when you can test and validate something is working as designed. I noticed your test device enclosure looks 3d printed. I really enjoy the process of using CAD to design and then print solutions on my 3d printer. It's so cool that technology like this exists and you can design and manufacture a solution in such a short time.
Thank you for the continued work to improve our sport! These videos are very informative and entertaining. I’m looking forward to seeing the final product and making a purchase when available.
Will the prop be available in multiple sizes?
I love the idea of the prop, cant wait to get my hands on one
Great video!!
Congratulations. Well done.
Awesome! So exciting Miro! I design and sell electric propulsion systems for ultralights here in the US. If you want a data point on what the prop will do for an electric system I would love to be one of your early testers.
Great work from you and your team Miro. Innovation in all the right places. Bravo. I wonder if you have any thoughts on the Toroidal prop design?
This is so sick. Maybe you could have a set of two or three interchangeable spring pairs come with the prop for low/high altitude flying. Been following this project for a while, I would love to test this out. Very awesome to see some innovation in the prop department.
Very interesting! Can’t wait to see this or try one. Prob a lighter set of springs for higher elevations.
Awesome concepts. I’d love to test one!
Reminds me of the boat props that do this, I think they were called torque shift props.
Hey Miro, could you do something like insert a washer under your spring to increase the force at low altitude and have it removable for high altitude flying?
For higher altitude we will need the prop to start downshifting later = more preload on the spring. But we need it to finish downshifting at the same rpm that is the whole shifting will happen quicker >>> we will need a softer spring.
So exciting. Thanks for your leadership in the space. Do you think the high altitude version will be a different spring/spacer combination or a different unit?
Sub 70kg trikes are becoming very popular here in the uk therefore, it is likely that there will also be keen interest development this product. I myself would very interested as I'm sure there is little engine/load operating differences between the 2 types of flying.
This prop may be a game changer - keep going please
Really excited to see innovation in the paramotor world. Thanks Miro.
Would love to build you a bluetooth module for your measurement system so you can record and read actual numbers on your remote phone screen instead of trying to spy some LEDs awkwardly. That said, a quick bodge that gets an answer is better than no data, nice work!
You are very correct. It was a quick and effective solution for this purpose.
I might have an idea for a next level device for further research. Please reach out to me at miroslav@scoutaviation.com. That would be awesome
He alive, alive!!!
great work!!
I’ve been flying the scout one carbon for about four years now. I’ve never looked back. Congratulations on pushing the envelope even further Miro.
Hi d zig I am really considering a scout what do you think about the machine thanks Andy..
Great job and looking forward to it. I have a scout and wouldn’t mind doing testing phase. I’m here in Indiana USA and we fly very often
Fantastic work Miro! Keep going!
Great way! Very interested to see this on the market.
Awesome work! Pushing innovation to improve the sport!
Amazing! I’m definitely interested in one of these props!
Very nice! I will definitely buy one when it goes on sale.
That's pretty cool! Great experiment setup.
Nice work Miro. I'd beg to be a tester but currently flying a Top 80.
Interesting
would love to see pitch change gear box design like on bell helicopter tail rotor gear boxes. Make it cable actuated. Pilot controlled on demand feathering of the prop.....
Super cool 👍 that’s awesome ‼️ congratulations 😃
How about a toroidal propeller on a paramotor , since they are claimed to be more efficient and less noise than a traditional prop?
I fly a moster 185 MY22. Usually fly under 3,000ft Would love to test one!!!!
I'm so excited for this to come out!!!! Can you put me on the list to buy one thanks 😊
Thank you for your efforts and the ongoing innovations that advance this amazing sport for us all. Your prescission and attention to detail is second to none, quite refreshing and instills great confidense.
Maybe making it more lower-profile by moving spring kit into prop plane would help?
Pick me I want to test :)
Oh how I would love to have a scout and test this prop, but I don't see me getting to upgrade anytime soon. 😢
15:06 ME ME ME ME!!!!!!!
What about a spring setup that engages centrifically instead of relying on the resistance from the prop? Similar to how centrifugal clutches/ torque converters work on go karts?
Fantastic 👍👍
Please tell me you have taken out a World Patent on this, it has application to things like turbochargers and jet engines.
How do we sign up to test these out?
Which parameters are responsible for shifting the pitch? Do you shift by help of radio?
Miro, would it be possible to have a small servo motor programed to change prop pitch at a certain rpm , or air density, or with a manual button like trim on a boat engine?
eu quero muito testar. faz tempo que assisto e me interesso pelo assunto.
acho até que se pudesse, faria uma hélice de 150 cm para usar em trike. imagina as possibilidades de cross country ?
I’d test it
Excelent! How can I trie one? I'm from Argentina
What length is the prop overall?
If this knocks the fuel consumption down towards Atom levels, this is definitely a contender for lighter comp pilots to get economy and power from the one unit.
Do you have a retail price estimate for these?
Just wait till he makes the same prop for the Atom 80;)
@@LukasKuhelj I can’t imagine it’ll be too different to the moster version, possibly just the case of changing spring tension and blades. The benefit of the moster being more economical, for classic comps, would be that on eco tasks you’d be saving fuel but still be able to reach full speed with the higher power demands of the top end gliders. The Atom is economical but struggles to keep up with top end speed of say the Warp and Viper without sizing up thus loosing most of the benefit of having a high performance glider in the first place. An Atom factory 100cc or 125cc would be a nice all round engine.
@@DanielJonesParamotor ah yes you are right:) As a Pilot who weighs 75kg and goes in the air with a moster & Roadster 3 26m I sometimes forget that there are configurations where the thrust is not enough :D
So, 12 months have passed, what is your opinion now, should I fit a Variomatic? Should I fit a Variomatic to a Vittorazi EFI engine?
The variomatic is in production now.
We tried on the EFI but the engine did not work with this prop. Vittorazi has promised they will try to make a new fuel map special for this prop. Theoretically efficiency gains should add up although maybe not 1+1
What is the main profits of such propeller in reality?
Updates?
Has anyone looked into toroidal props for noise reduction?
Hi I am flying with my polini 250 ds , and using 130 cm wooden propeller 2 blade firbtrike flying , can we use it or we need to change it
HOW DO I TEST OUT THESE PROPS?
the stage you're in now looks very promissing ... if that all works very interested to test
just finished a paramotor adventure in Saudi Arabia. Of course I took the prop with me. It worked perfect.
@@SCOUTaviation will test and confirm
Congratulations, next step 150 cm prop. Step after that, 3 bladed prop.
Why would you want lower pitch at higher RPM and higher pitch at lower RPM? That seems like driving a car while stepping on the clutch and the gas pedal at the same time. You will spend more gas doing that.🤔🤞
Low pitch/high rpm equals best power/thrust for takeoff. High pitch/low rpm equals best efficiency for cruise. Low pitch is like low gear - best for getting going, and high pitch is like high gear - best for going fast.
Very excited to see your passion coming to fruition.
In regards to test pilots, this dude would be a good contact for research and development feedback. He's a buddy of mine that is active in the performance paramotor community.
