The Lightest Propeller in the World.

[@aviator]

Joel is the man... Have loved having him at the National STOL events. Tigershark rocks! Have been using E-props for years. Awesome stuff!

[@lspringerjones]

Tucker Gott on KZbin has been using E-prop on his paramotor for a long time. I think he's also a dealer.

[@willseyaboutthat1211]

Need to get more of Joel in these ! Great video !

[@assiegordon]

I got an e-prop this year on my SZD-45 motorglider. I got an added 200 fpm in climb rate and another 10 kts cruise. And gliding improved too because of the skinnier blades. Really love this prop!

[@portnuefflyer]

Wow, that's a huge jump in performance, and as one who does the occasional dead stick ridge soaring in my own S-7, those skinny blades are starting to look better!

[@assiegordon]

@@portnuefflyer yeah, I was shocked too. I've kept rechecking but the numbers are true. But just like Jonas found out with the airbike, my static rpm is higher than dynamic because of the root being stalled when static. It is backwards from a normal prop. I will tell you one thing, there isn't a straight piece anywhere on that prop blade. It is optimized in full 3 dimensions, does not care about wood grain and machinability. I'm very happy with it.

[@regardtcoetzee]

E-props are hands down the best ground adjustable props on the market!!

[@robertcorbin2749]

Love this video. you have such cool friends. Thanks for sharing Jonas.

[@BushCat]

We need to check them on our BushCat:)

[@williamwintemberg]

Always fun and sometimes, educational! This was both! Thanks Jonas and Friends!

[@robstanton9215]

Anxious to see what you’re hanging that E-Prop on! Take care Brother!!🤠👍

[@dawnhasbroken6304]

Hung out with Joel over the 4th...great guy. Thanks for the cold water!! 🎆🎆😄😄

[@kevinberry5793]

E-props are very popular in the paramotoring world

[@craxgt]

Got an e-prop three years ago for my CT. Just night and day compared to what I had fitted before. Just love it!

[@jakematijczyk6905]

Great video. Joel was super fun to watch in pinedale thanks for the entertainment

[@gerryholland7274]

Fitted an E-Prop last year to my 503 Sluka. Awesome! So light you dont get the Gearbox chatter at low rpm's. Everypart of Aircraft performanceimproved 20% or more from the previous Ivoprop.

[@JonasMarcinko]

awesome to hear!

[@Clif_Brown]

I used e-props on my paramotor. Super light. Maybe need one for my airplane!

[@markjohnson9157]

Thanks for posting this. I’ve been thinking about getting an e-prop so the more I can learn about it the better. This was very helpful.

[@vangogle1]

The heavier a wheel is, the more hp it takes to turn it. Would be interesting to calculate how much less hp it takes to turn the light eprop than each of the other 2. It should get rpms up quicker for takeoff but also may give better cruise econ because takes less hp to turn it (all subject to the thrust for comparison). But would be interesting to calculate the hp requirements for each prop for given thrust to compare both cruise hp required and takeoff.

[@michaelspunich7273]

Jonas, this was an epic video! Those Flying Cowboys aint got nothing on you. Keep up the experimenting, the testing and stay safe doing it!

[@JonasMarcinko]

Thanks! Will do!

[@PghGameFix]

Love to see tests like this. In the RC world we do it all the time, but in full sized... who wants to spend thousands of $$$ to try? BUT... you may want to put a disclaimer... removing 5 lbs from the nose will shift the CG a bunch.

[@steveshaw8003]

Very interested in the constant speed e prop. Everyone I have talked to loves the way their airplane performs after getting one!

[@JonasMarcinko]

Im interested in it also! good to hear!

[@1656c]

Make that 3, for my pulsars. Gimme a hollar Jonas, btw its Capella Curt 🤣

[@KitfoxGrin]

I put the CS on Jones's old Kitfox and it was a significant improvement.

[@edenshorthousesthouse1925]

My flight aircraft has doors underneath so you have to climb in and has rotation on the outside of the room which flies.

[@ToddBerthiaume-m6e]

I runE- props on all my motors

[@patrickheavirland3599]

Hello from Minnesota! Great episode!

[@Biggie_Johns_Son-v3i]

Nice edit- keep up the product improvement testing :)

[@JonasMarcinko]

Thanks, will do!

[@barrysimmons5489]

Hey Jonas, Thanks, it's a a learning experience these experimentals, cause I don't know nuthin and I can prove it! Except it's always nice to see your beautiful bride Sylvia and your baby. . . Thanks for sharing. (There's holy smoke, but don't know about that other).

[@mikephillips9311]

Ok, so the longer E prop pulled better (80") than the shorter one (72"), but what about top end, were you able to test that? If not, I hope you can do a comparitive test on the top end speed differences, I think a lot of us would like to see that demonstrated. BTW, what did the plane weigh? Thanks Jonas!

[@tomcoryell]

Bet the DA ain’t so bad today!

[@rexgialla1970]

I have, It's the best that I tried , super performances

[@DWBurns]

I have to buy my Arrow a new prop. Hartzell will not allow me to eddy current my prop hub any longer. I am looking at the 2 blade scimitar prop for the Lycoming 200 HP C1C engine. Any and all input is welcome. We live in Ohio but like to go to Colorado. Not asking much.

[@L2FlyMN]

I have the 72 inch 3 blade warp drive prop on my single seat PPC, driven by a 100hp Subaru ❤️. On my 3rd set, after two sickening incidents. 🤦🏼‍♂️

[@johnfitzpatrick2469]

G,day Jonas from Sydney Australia. That is a very nice STOL plane. The seat, custom for the lumbar curve etc. Is it carved foam or thermosetting plastic? Best wishes 🌏🇭🇲

[@Wings_of_foam]

I don't know much about planes, but if you installed a clutch for STOL, wouldn't you be able to start with higher RPMs?

[@Goody2414]

Jonas, what prop would you recommend for a model 4 912ul currently 80hp but I plan on zipper kit . E prop has my attn , that weight off the nose has to be better on the older gear drive

[@JonasMarcinko]

Send me an email. [e-mail] I’m a dealer and can save you a little bit.

[@DiscusRussell]

When are we getting an update on the farming and the aircraft you have to build. Seems you are neglecting both vlogs

[@adrianchristopher5867]

Cool vid. Didn't know there was so much in a different rated prop. Yes the clouds are not usual. Your skies are being sprayed with Aluminum! DYOR. After that decide whether the U.S. is a safe place to stay!

[@vg23air]

i was looking for a prop for my loehle sport parasol ultralight, maybe i found it ?

[@davessparetime83]

on the E Prop how much torque can it take? Would hate to see it break a blade off under power.

[@mikentx57]

Did I see this right and he can go to a negative flap angle?

[@logankistler]

When do we get to see the secret airplane?

[@vg23air]

So is the E Prop ground adjustable for pitch, or fixed in pitch from the factory ?

[@gerryholland7274]

Ground adjustable with a very useful Angle Indicator Tool. Very Easy.

[@vg23air]

@@gerryholland7274 yes, i stopped being lazy and read their webpage and found that out THANKS :)

Maybe I missed it, but what was the engine? 912? Mods?

Is there an E prop that will handle a 150hp Lycoming?

[@JonasMarcinko]

I believe they are working on something.

[@ianmangham4570]

Any relation to Richard 🇺🇸 😮

[@slow3007]

this is about your airbike ,VIP!! take off that yellow fuel line!! the center of it gets gummy and lets gum slime in everything .go to aircraft spruce and buy the blue hose - real aircraft fuel hose. that yellow hose was sold by arrowprop..this was a hell of a problem with my rotax 503 . over heating? was your rotax built for regular gasoline like in snowmobiles or is it built for airport fuel that is leaded fuel. and are you using 10% gasohol , even that fuel you by that says alcohol free has 10% .that fuel set in a container and watch the water settle in the bottom after 3 weeks . .my 503 had a pullstart with a internal belt fed fan with no cooling problems on my minimax .

Hello I'm new to your channel cool content sorry I gotta let this off your actually flying bro, it's actually interesting how this is possible because it's literally motion over a greater motion (gravity) I'm a good jumper I could box jump on to my mum and dad's fridge if I wanted to it's just I want to go higher if I can double my energy would I be able to go twice as high?

[@brettkent9851]

Tranq or benzo?

[@edenshorthousesthouse1925]

Isnt either it's an LG also

[@edenshorthousesthouse1925]

A contained pressure changed direction at a different rate is how I counter gravity

[@NunoFlyer]

Yes, but for small people eprops dont care about support, they dont care just want money in your side, just support and helping sponsored guys, this is the life of poor people around this planet, the type of these people dont remember that started the company from zero with support provide by small people!

[@portnuefflyer]

Too bad it looks like a toothpick! My $2,000.00 78" Prince P tip prop weighs 8 pounds 11 ozs., just the prop itself, but it's the best prop I've tried as far as getting you out of the hole.

[@JonasMarcinko]

I have an e prop if you want to try it! It’ll be interesting to see how it works on your plane.

[@portnuefflyer]

@@JonasMarcinko The noise it makes would be of interest to me, especially as compared to the Prince (which almost makes the Rotax sound like a little radial). I flew 3 hours yesterday and never got over 5000 RPM, burning 2.7 to 2.9 GPH much of the time, kind of typical for me, it'd be interesting to see how it does in that flight regime.

[@jbarnes7798]

​@JonasMarcinko Do you think engine out glide would be better with a thin Eprop?

To put this in perspective, the M1 Garand rifle that the US used in WWII and Korea weighs 9.5 lb. Soldiers had to carry this across Europe and on Pacific Islands. I have a couple myself, I like to collect WWII weapons.
