Electric Paramotor Review

[@ClarkKulper]

The sound can be greatly reduced by changing the propeller type. If the blades had small curved tips, this will change the noise level. I can't remember what the exact name of this type of prop is... But it does make it quieter.

[@Hhsteck]

Great video! Nice to see the paramotor packed up and then brought to flight status. Thanks for the professional review and your personal comments. I agree with you we are seeing the future of paramotoring.

Why does that matter? Get noise canceling headphones, or ear muffs that insulate your ears from the sound!

[@inthebriarpatch]

I'm reading comments while watching the video and cant hear a word you typed.

[@yourmeister]

It's loud due to the smaller props having to spin faster. But the engines are silent, produce no vibration and, yes, most importantly, the feature you mentioned is a great safety win. Not only will simple electric motors need almost no maintenance, they can come to a full stop and then back to running at a moment's notice. Whenever you feel like it, the props will become stationary, and whenever you need them to give you thrust, they will. You can also make them automatically turn off whenever an obstacle is near. It basically eliminates the very possibility to shred anything.

[@Thezuule1]

My first thought was that the crazy torque from an electric motor was going to cause some serious issues for a paramotor but then I saw the four blades.. Brilliant. The amount of instant force that an electric paramotor could put up would be a game changer.

[@MichaelRainabbaRichardson]

I am so with you. The ability to instantly cut the motor with a knowledge that will start back up instantly as needed is amazing. It's like a powered glider in that regard. I look forward to see how this develops.

It does make a 2 stroke look like a coal fired steam engine.

[@dickfitswell3437]

The cost is twice the price of the most expensive gas engine. I don't see this coming to market anytime soon. Throw in bidenflation, which is now a recognized word, and this can't be produced the same way that gas engines are. It will be a class thing and by that I mean only the richest ppl who fly can afford it.

[@MichaelRainabbaRichardson]

@@dickfitswell3437 if you think Biden is responsible for the inflation, then I won't be taking any aviation advice from you 🤣. You are aware that we just spent 4 years with an idiot as president, who literally encouraged the spread of a virus that is destroying "the economy" right? The reality is that we've had it very well for a long time and because of the pandemic, America cannot take advantage of the rest of the world as easily and so our prices are going up. The fact that so many people don't want to work under conditions where they're at risk for catching the virus, isn't helping either. It's not rocket science. The fact that the public markets were doing well prior to the pandemic isn't credit to that president in the same way that the current inflation cannot be credited to the current president. These things take decades to set up play out. Only temporary impacts can be credited to recent activity. Covid-19 isn't temporary or new. Also, twice the price for the motor isn't that big deal considering the difference between being able to restart a motor when you want and not for someone like me that likes getting altitude. For the guys that need more constant power, that price differential may not be worthwhile.

[@svetre87]

Hi Peter, I didn't try it either, but there seems to be a consensous in the para-world regarding risks while thermalling with a paramotor. The main Problems are related to wing loading, drag of the Cage and twist rsik. Higher wing loading means worse collapses, drag means smaller angle of attack and Twist is self-explanatory when you have a 30kg backpack :) I don't say it doesn't work, but why go thermalling when you have an engine strapped to your back (which doesn't really help when it's turned off)?

Do you think it will have enough power for acro for you? The 4 props won't get as much thrust as a single (tri/quad) blade. (Not as compact or torque friendly) I'd imagine they'll unroll a higher power unit soon. I'm 300#, so have been speaking to different E-PPG companies to try to find something powerful enough for me.. my favorite so far may be e-glider.com where they aim to optimize for free flight, and the blade collapses to reduce drag. This might be a pretty sweet option if you want to get to altitude on power, then do some acro on glide.. always with power at your finger tips if you decide you need it ;-) (E-glider has some pretty powerful engines available, but they don't pack down like the eppg, and may be a good bit more expensive.)

How long did the battery last and will it fly on three motors?

[@anoniemous2136]

he says that it has a 30-40min range @ 10:07 As for flying on three motors, I think it would depend on how the motor failed. In theory you could unplug one and it would still fly, but if you had the prop break on one you would want to stop to prevent further damage. Also by fly im assuming you meant powered flight, you can glide extremely long distances in ideal conditions using up drafts to give you more altitude.

Unfortunately you can't change the prop setup that much really. Motors really support a certain variation of props. So you'd have a completely different configuration to try to go to a double or single prop setup, which may not even be currently feasible.

There are gasoline capacity limits for ultralights. I wonder how many decades it will take for the FAA to figure out an equivalent in battery capacity especially considering the variables in energy to weight ratios of chemistries.

[@adambrantley9319]

Can the battery be dropped in flight in case of fire?

[@10661956]

Yes, I have a quick battery mount/release on my X4.

[@JoeR203]

And it makes a hell of a leaf blower.

[@thomascoscetta6452]

How much is this unit?

[@patrickfain9318]

Does the cage feel strong/sturdy or on the flimsy side? Thanks

[@glydrfreak]

Patrick Fain it’s definitely not a flat top 😂 if you trip, you’re likely to flex the hoop/net into a prop.

[@FlyHighParamotors]

The cage is an amazing design and felt sturdy, but you should not be crashing it as the bottom section may gave easily.

[@mahammedalqrashi]

Hi. Could you please tell me about the battery. How many hours remain it operated?

[@elli003]

The noise on that thing ! Have you run a db meter ?

[@TheArieldp73]

Nice, how much weight?

[@rossab123]

Put a small windmill blade behind the motor that spins freely and generates power. Face it opposite direction to reduce torque effect

The purpose of advancement, education, science, technology, engineering and development is to make life easier, simpler, cheaper, safer, healthier, happier and more fun for everyone. Electric and alternative powered vehicles is the way! Can't wait for all vehicles to be electric or similar super low maintenance no or lower noise systems to predominate. Interesting this four prop unit seems louder than the gas mono prop ones. The less noise the better. I only watched videos, never been near either types. Never even heard of nitro units. Safe happy travels

Imagine how much money it will cost to build an electric grid to satisfy the requirements of such a wish!

[@evaluateanalysis7974]

@@nojtom Imagine the cost of building a network of petrol stations! These new-fangled cars powered by internal combustion engines will never catch on.

[@calvinhenshaw2147]

where is this ?

[@quillanthrasher6846]

How much does this motor setup run for?

[@VladOnEarth]

What kind of flight time does this thing have tho? Are 4 motors more efficient vs single motor setup?

[@jakegarrett8109]

Single motor would be more efficient. Probably slightly cheaper with 4 smaller motors to use common UAV motors, at least until there are more common big UAVs that use the giant single motor.

Pensacola beach park east. Sabine bay in background.

[@64wing]

Off topic, but do the birds in the background remind anyone else of the locator beacons that firefighters wear?

[@bradbrown2168]

Need an hour flight. Doable?

[@neosugus]

Bit noisy? How much flight time at a cross country level flight does that battery give you?

[@jakemartindale7016]

What’s the battery spec?

[@maxbootstrap7397]

Cool. What is the weight... including batteries and everything else? And how long will it fly? And how far can it fly on one set of batteries?

[@Wintermute909]

Yeah kunda *the* important questions.

[@monicasmyther8976]

and how long it takes to charge all the batteries...

[@Vicariously...I]

And are the batteries easily changed out? It would be great to have two or three batteries so you could fly, land, swap/charge, fly, repeat.

[@javierestrada6927]

What about a solar powerd one or hybrid

[@rajasarapi8082]

Seems that propellers need to be designed in a way to reduce noise. I am sure there are studies that can help with development. Someone below recommends Xoar props, there has to be a quieter and efficient design.

[@NextStop2030]

I would deff be switching those props for some Vess or Falcon 22/10-12 wide. Or to really cut the noise a 3 blade.
