I'm still considering what unit I want to buy. I love the look of the Gravity but I hear it's quite hard to get in touch with the company if you need to. That scares me. By the way, can you tell me if you can safely fit a 140cm prop on the Gravity like you can the Limitless? (I like the look and set up of the Gravity WAY better but at least with Limitless you can actually get in touch with the company if you need to and it runs a 140 cm prop).
When buying a paramotor, you have to ask yourself what you want in the frame. For me at the time, small disassembled size and an airtight gas tank were top priorities because I drove a civic. Nowadays, I think my priority would be lighter weight and quick disassembly, not necessarily small size after disassembly. I would not consider a 140 cm propeller on the defiant, it's definitely made to fit a 130. I fly with a 130 and a 127 to good effect. I also flew a PAP with a 140, and couldn't tell the difference. Unless you're doing tandem flights or really going for max range or climb speed, I wouldn't put much emphasis on the 140 requirement. Seems like everyone is frothing at the mouth for it, but it's a marginal improvement at the cost of ground handling ease and size of parts. For what it's worth, I've never had problems contacting the team at glidersports/gravity for help or for spares. I've also never really torn mine up though.
I've always loved the idea of a small fan motor and came across a "ancient" video on YT where a man had put a prop on a weed eater 2 stroke motor and was able to get some decent speed on roller blades. I live near the water and that what a great wee motor that can be used on water and on land without ever taking it off your back. The concept of a boat/bike became cumbersome but the simple backpack motor had my heart. I used the 212 predator motor as a PM but its heavy with only 6hp and terribly inefficient. So I decided the DLE170 would be my next venture. I wonder if taking the motor only and going cheap on the rest would make a good cheap kit for land use only? Since $3300 is 3x the price of the motor alone.
My defiant is a bit of a special case, it shipped new with "not a perfect net" (which I knew about) for reasons I can't discuss, so I had to add 2 rows of netting, seen in white, in the lower left corner.
Nice video, Avery. It was a concise, detailed, and fair comparison. I wasn't completely clear on the fuel tank on the Airjet. Does it really only have a ~5L tank? If so, 45 minutes max of flight time is a big limitation, in my opinion.
other then the added weight, is there something that would making the tank bigger or adding to it during flight... I get safety and what not... I'm wondering more about the mechanical limitations of the motor being unable to carry the added weight and still get airborne or not having access to the fuel tank during flight? TIA
@@suspiciousskepticism6306 another 6 lbs for a gallon wouldn't be impossible. You probably couldn't fit much more than 2 total gallons down there due to the exhaust though. I will look for a larger tank.
@@AveryFlies makes sense, thanks for getting back to me and great content by the way, glad to see someone experimenting and sharing ideas... Rather than pretending you're not just chasing clicks to feed the machine....
Atom 80 would still be more thrust because it's geared to swing a larger propeller. The DLE170 is lighter but has the same power as an atom 80, it just loses efficiency with the little propeller
probably. Too big and you'd be too heavy. Something in the 100-250 cc range, with a good belt or gear drive, should work fine. I've seen as small as 60cc motorcycle motors fly a paraglider before.
Have you looked at electric at all? I don't fly but I am interested. With most motorized things nowadays, I bypass internal combustion as an option. I know about energy density etc but electric is just more attractive to me personally. I've seen folks using large scale RC components. Twin ducted fan motors seem like a good option to me.
@@canolando3499 Yeah, the issue for me is that the battery to reach that flight time is $1k+ and doesn't get lighter as you fly. I will wait for the next breakthrough in battery tech before jumping ship
@@AveryFlies If you add up the cost of gas and oil plus flying 5x a week you will recoup your eppg battery in less than 1 year. I was probably flying before your parents even met in the early years of ultralights early 80s i think. Up until 15 years ago i flew various forms of light aircraft all powered by 2 strokes. I loved 2 strokes although they let me down many times not only in aircraft but everything else that is powered by them. I had many engine outs as I flew a lot. My last ppc i had I abandoned the 2 stroke and went for a generac 4 stroke. I used this engine on my equiptment in my business and it was bulletproof. You could let it run close to full throttle all day long without a hickup. For aircraft it was a no brainer. For ppg use it adds a lot of weight. Hense the eppg. I have no interest in a 2 smoke ppg. But many do. Keep up the good reviews and fly safe. Its not the fall that kills you its the sudden stop.
No comparison for me. The direct drive is so little thrust I wouldn't even get to the sky with anything less then a tandem wing... Other parameters become irrelevant. Good for kids and skinny ladies.
Can't put into words how thankfull I am for the fact that you included metric units!
Wing weight capacities are all metric, so I will strive to do it all the time from now on
Great editing. Concise presentation. Excellent camera angles (we can see what you are talking about).
That's the goal! Thanks for letting me know I'm on the right track. My videos have just been so long recently
Nice tight editing all was good. Nice comparison, I had not heard of the AliExpress unit but it looks pretty fair for $3300!
I've got the Defiant serial number #2. Loving the frame 🪂👍🪂
Love mine. Quick to assemble, and tough. A fellow student has one and really butt landed hard 3 times in a row, not even a scratch on the hoop or tank

Yeah, if you're using it for ground propulsion I don't see a point in buying a flyable machine
@@AveryFlies For the purposes of a Universal "drivetrain" eg boat, scooter, ebike and such.
REAL GOOD ENGINEERING ANALYSIS.
Nice video. Big fan of risky biscuits too haha 🤘 someday I'll walk into the sky with my atom 80 🕊️
Great video, thanks 👍
It looks like you did something with your Defiant netting, I would be interested to see what concerns you addressed and how.
My defiant is a bit of a special case, it shipped new with "not a perfect net" (which I knew about) for reasons I can't discuss, so I had to add 2 rows of netting, seen in white, in the lower left corner.
@@AveryFlies I hear you on that 😂. Thanks for the insight.

Yes, it really is that small. 1 US Gallon.
other then the added weight, is there something that would making the tank bigger or adding to it during flight...
I get safety and what not...

What voltage battery and amp. do you use for the electric starting on the DLE 170 ?
1500 mah 6s (22.2 volts) amzn.to/3ei1ipX
It also runs the ignition to create spark.
@@AveryFlies Thank you so much my friend !
Awesome! Great video!
What prop are you running on the dle?
XOAR brand 2-blade, 32x12 carbon prop. amzn.to/3Da0U6Q
I wanna see that airjet launch a hangglider! Another nice vid btw...
Not sure about hang glider, but I flew it under a medium Apco hybrid today. It technically hangs, right?
@@AveryFlies interesting...I have the apco lift ez 27.5. Lotsa lift but I'm heavy pushn round 200ish. How you like the apco?
Wait is that a single skin?
@@flyingtime5501 the hybrid is half double skin, half single skin. Very efficient!
@@AveryFlies nice...apco seems like quality gliders and the company has a great reputation so that's a plus!
An Atom 80 would be a great comparison. That’s what I’m considering.

Can you sell mi one second hand one...
I would love to see you try to put a small motorcycle engine on a paramotor I always wondered about that and would it work or not.
probably. Too big and you'd be too heavy. Something in the 100-250 cc range, with a good belt or gear drive, should work fine. I've seen as small as 60cc motorcycle motors fly a paraglider before.

I have, and I even made one in my earlier videos, but it's still not cost effective and flight times are poor.
@@AveryFlies I heard of a guy getting a full 60 minutes of flight time on an electric ppg. I can deal with that.
@@canolando3499 Yeah, the issue for me is that the battery to reach that flight time is $1k+ and doesn't get lighter as you fly. I will wait for the next breakthrough in battery tech before jumping ship

Keep up the good reviews and fly safe. Its not the fall that kills you its the sudden stop.
Thank good report
👍
Good editing - better video.
I order 10 pis Bangladesh country
Sorry, I do not sell paramotors, just fly them.
No comparison for me. The direct drive is so little thrust I wouldn't even get to the sky with anything less then a tandem wing... Other parameters become irrelevant. Good for kids and skinny ladies.
yep, definitely lacking in power and not a good choice for most people
who has 2k to waste on alibaba shit?
Well, it wasn't a waste, because it does fly. But I guess I had $2k to "waste" so you didn't have to.
Next step increase the hoop size and put a bigger propeller 130cm maybe. Great video thanks.
got to find someone who can machine the requisite parts for a belt reduction. If you know someone, I'm all for it!
