AliExpress paramotor: Upgrades and First Flight! | Avery Flies 

Also remember that the Chinese weigh half what Europeans do lol

@@Surferant666 or us Americans for that matter 🤣

no proof any god has ever existed except in senile old mens minds.

New rings usually come with an undersized gap .. which you must manually adjust with a ring file. I guess you got lucky because it didn't seize after you put power to hit and heated the motor. Heating rings expands them, reducing end gap.. if too small, the ends butt and excessive ring pressure will damage the motor.

Go fill out an application at the nearest plumbers or electricians union hall for an apprenticeship. Cause your gonna lose an eye with this very dumb idea.

Yeah, definitely not getting rid of my normal defiant. But it's cool to have options

The openPPG X4 uses an (electric) RC engine ... but it does use 4 of them.

Thinner base gasket, open the exhaust port, Check the squish on the TBC, Dual stage reed block (if it as a reed block). And re-time the ignition. Also, maybe want to drill a small hole 1~1.5 mm hole on the lower piston skirt facing the exhaust port. And open up the intake, while re-jeting the carb, and run 104 octane gas with a exhaust gas temp gauge. 2 stroke are fun and cheap to play with. How far you want to push it is really up to you.

@@fredpinczuk7352 Of course that is all valid for squeezing every last bit out of an engine. But most of that is beyond the scope of simple "bolt on's", which was the scope of my comments. Proper tuned exhaust, and properly timed ignition are the 2 most beneficial gains to be had. They get you 80% there. Proper ignition timing also means proper advance curve however, and that requires a CDI (preferably CDI) that has the proper curve of course. Simply running 104 octane fuel wont get you anywhere unless you also do the mods (deck the head, lower squish band, thinner base gasket etc.) required to increase compression ratio. Higher octane does not provide better power in itself. The higher compression does, and we need higher octane fuel to prevent detonation. To add to your advanced list, some other mods would be to fully port the intake, exhaust and transfer ports. Stuff the crank case for better case pressure. All that being said, I am betting you could get a significant increase in usable power out of one of these engines if you done all that. Whether or not it will last after all that is another story altogether. By the time you do all that any cost benefits have gone out the window also.....but its fun to tinker and see what you can do.

Yeah the pipes basically act like vtech. It alters the exhaust scavenging based on the pulse rate of the combustion. Having a 2t bike it's remarkable how difficult they are. There are books describing the effect and how to change the scavenging but good luck understanding it

all gets a bit sketchy tho - when you got one expansion chamber operating across two cylinders............... ??

@@raymondo162 good point I didn't think about that. May actually hinder scavenging on a cylinder. Where are the engineers when you need one? Do the cylinders fire at the same time?

They do.

The cylinders are 180 dg apart so fire opposite each other. probably wasted spark so spark when piston is down too. the pipe will only partially work on one cylinder. as the tube leading to the other will waste some of the return pulse. If you used two tuned pipes on each cylinder it would gain more hp. There is a formula to work the distance to the Convergent & stinger parts to the port to rpm. You should have gapped the rings in the bore as if it is too small a gap it will seize the engine when hot.

Yep, had to retune! That added a lot of power

Glad you liked it!

They are bowman rings, already perfectly set up and the guy is brilliant to deal with.

I flew it the other day, it got me to about 1500 AGL in 15 min. Burned almost 1/2 gallon in 20 minutes. So endurance and climb are poor but it can get you up there.

@@AveryFlies typically when I mid day with motor (no mountains in east Texas) we climb to 1000’ and hook a thermal. It’s a bit harder below that and I like to keep a hard deck of 750 to 1000’ mid day. I’m 220 hooked in, so that prolly won’t work for me, but the set up is nice for sure!!!

Oh I bet! It was a pain to put on though, it's not coming back off haha

I thought about it, but the market is so small and it needed so many fixes it just doesn't seem like a good idea. Maybe I'll become an RB dealer! Their minimot uses the same engine

Hey, nice to see you! I won't deny that I need help in areas that aren't my expertise, thanks for stopping by!

Is definitely a small motor for a small person. Of course I know tucker, I bought my wing from him. You would probably want a moster 185, Thor 190, or Polini 202 or similar.

@@AveryFlies that's awesome bro. Also great video. I appreciate the response. I don't know him personally but ran into a video. Im a Aviation Mechanic stationed in Atlanta. This seems the cheapest way without spending a fortune for a plane or mosquito helicopter. Thanks again man.

@@lancedooley7558 it is the most affordable heavier than air form of flight, and it's very freeing. Find an instructor and get up there, you'll love it!

@@AveryFlies you've just earn a subscriber my friend. Keep flying. I will be soon. 😁😎

I was hoping someone would catch that

Hopefully I've made it clear that this was super sketchy. I figured I would make the videos before someone bought this on a whim with no info.

Yep, I have been informed of this. Either way, the rings helped.

Happy to help! If you've been enjoying the Xcend, the vantage will launch easier, maneuver better, and fly faster. It's a good pick for more speed and better handling if you also want to paraglide with it. If you're considering a ppg only wing, I would look at something reflexed like a Spyder 3

@@AveryFlies thank you, that is a tremendous help. I do about 50/50 free flight versus powered. I'll start testing out wings and see where it takes me. Plan on setting up vantage 3 and epic 2 test flights.

@@wardified8566 you might also try the BGD echo, the lighter version of the epic. It's more similar to the vantage in weight and ease of launch

No fuel, before the exhaust upgrade, I measured 34 lbs.

1: $3300 including upgrades 2: the engine is a DLE 170, 170cc, 17.5 hp @ 7500 rpm 3: probably would not fit in the suitcase, broken all the way down, it would probably fit in a 24"x36"x36" crate or box. The hoops come off but the spars are built in, and the main frame is an A-shape from the side. Definitely smaller than any other I've seen, but not that small.

@@AveryFlies Thanks man. You did not happen to take pics of the box it shipped in by chance? I'll connect with the vendor too. Where did you get the "drill guide" from?

@@GDFred88 You can see the original box in the first minute of my first impressions video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-laPZRjj8QPY.html the drill guide I got on amazon, it shipped from horizon hobbies. www.amazon.com/Dle-Engines-Propeller-DLE170-DLE222/dp/B0051W91MA Keep in mind that this frame needs a LOT of work to make it safe, I have 11 things you need to change or address before flying: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bsOynmKp0KA.html it is not a good first time paramotor, and should be approached with caution. Beach flying does sound great though, check out @ParaSurvival he flies the same frame at a beach in Texas.

Happy to hear it! Check out some of my other videos, this is NOT a typical paramotor. They're usually heavier and way better. I've documented basically all my flights since the first one. some resources: FAQ: docs.google.com/document/d/1ivaOsXf7f7T5jlCqqdD7my6KwQoJ9BXNhz89HzZGZ-Q/edit?usp=sharing usppa.org parayelp.com facebook.com/groups/paramotor You can also drop me an email, the address is in the about section of my youtube channel

I did a 2 hour break in routine before changing rings, but the RC guys raised cane. Apparently this engine runs so rich on oil (30:1) and needs airflow that it's best to just fly it according to them. I ran it in the idle to 3000 rpm range for about 30 min before power pull and recording the running for good measure though.

I weigh 165, the motor with fuel is 40, I guess the wing is about 15? So 220lbs/100kgs. I am underweight for sure, but it flew easier that way

The gap is what the manufacturer made them. These rings are purpose built for this engine, they are widely regarded in the RC world as a high quality, drop-in ring set. I trust whatever gap was made with these rings given the reputation of the company making them. I will be sure to measure the gap if I have to disassemble then engine in the future though.

Propeller is available here: amzn.to/3aYDEgO Make sure you watch my other videos on this unit addressing the problems it has

GoPro Hero 8 Black with a SnapMount magnetic mount. The back plate of the mount goes inside the last cell of the wing, and the camera attaches to the plate magnetically through the bottom fabric surface.

Way too expensive!

Probably still 160 or less. That made it flyable for me, at 165.

Back when this video went up I had less than 900 🤷 thanks for the sub!

I MISSED THEM! 😂

They didn't specify. The blades themselves were thicker but I couldn't notice a difference in pitch. There clearly was a difference though, changing the prop made a huge increase in thrust.

@@AveryFlies Thanks- yes, the first prop was way out of the power band of the motor.

170cc, 17 HP @ 7500 rpm

I bought it from a Thai gentleman who no longer makes them. I would recommend finding a motorcycle shop to help you

Understand.Thank you!

The falcon was my first choice actually. Their CF 32X10 should work just as well or better than my Xoar.

@@AveryFlies Thank you very much and more power to your chanel.

I flew the falcon,its excelent ,improved the rpm a lot,thank you keep up the good work.

I did not build it, I bought it on ali express. You can find the link in the video description. Total cost after upgrades $3100

Well yes, but all other things being equal, more rpm = more thrust up to about mach 0.9 tip speed. It's not linear but it's the only accurate measure I have.

That's a pretty broad question, do you mean what wing? It depends on your skill set, instruction situation, and mission. If you mean what paramotor do I recommend, I'd still need to know what you're looking for in a paramotor. Ease of assembly and small size was important for me, so I got a gravity Defiant with the Moster 185. If you have a big vehicle and space to store it, then that might not matter to you too much.

@@AveryFlies I was referring to the combustion motor, not wing. Have you seen any success with a DC motor and battery?

@@DukeCannon if you want to go electric, you'd be looking at an AC motor (aka brushless) and lithium batteries. They work, but they're expensive. I tried building one, thinking it would be cheaper, and it was not.

Yeah, it doesn't help efficiency, but it still flies.

I will stop doing that in video endings, apologies. The front camera angle is wide because I can't see what is in frome from the other side of the lens, and I also try to show some of the wing.

Yeah, $300 cheaper, but almost as much oomph as a 185

Probably not, close this video now. The power lines are on the other side of the road, which were a good 300+ feet away when I stopped the take off. Bobby, the guy saying power lines, was a few thousand feet back at the parking area with our vehicles. I also stopped because I was about to cross the runway at this small airport. Sorry to disappoint you. Hopefully you didn't watch the video

@@AveryFlies LoL, thanks for the update.

@@jesseakers7298 🤣

Its a shadow on the shorts, you're not the first to think that lol. I do appreciate the compliment though

MuH cRuMpLe ZoNeS!

I was a long ways from them, I don't get why he was so concerned about them

It's me. I'm looking for the cheapest. You found me. I have a life insurance policy. I also took the time to make it safe, if you'll take the time to watch my other videos. The engine is the biggest cost saver, and that's not what does the actual flying. We should all be planning for motor outs all the time. I put this series together for two reasons. One, to show people that you really do get what you pay for, and two, show why paramotoring is generally so expensive there's a lot of research and development that increases costs in order to make it more reliable and safe.

Not!

@@AveryFliesyou did

For several reasons that I won't get into, I can promise you didn't see anything. It's a crappy position but no, I was not commando.

@@AveryFlies 17:27

@@Clearanceman2 I know the time everyone thinks they saw something, but like I said before, FOR SEVERAL REASONS, no you did not see what you think you saw 😑 I appreciate the compliment though, I guess?

I'll fly it if you buy it! Those things are EXPENSIVE!

So if you watched the video, the moral is that it does fly, but you probably shouldn't buy one.

Stolen is a strong word, maybe revisited? No hard feelings

@@AveryFlies im just joking youtube brought me here after i watched the recent tucker gott video

I'm getting a lot of that recently, thanks for watching!

It's a 2 stroke with a crappy muffler spinning something small and fast, so not too far off.

Yeah, but this lawn mower and camping tent FLIES

@@AveryFlies I wanted to do this but it's way too yuppie expensive. Could get an actual airplane for the price of a midline parazoomer.. Well little one.. used..

@@Dr_Wrong true. But hangar space and, if it's not an ultralight, training can be expensive too

@@AveryFlies $3k - 5k for paragliding school too. Needn't hangars, still need tiedowns. Drier in the rain, long distance travel, comrades.. A dirt-bike engine and a large bag for $8k - 20k is a disappointing exclusionary yuppie hobby price gouge.. imo I've enough projects, I won't bother making my own wing too.. Bummer for me, I reckon..

@@Dr_Wrong it's definitely not for everyone. I hope you get to experience it some time though, maybe through a tandem. It's a very freeing, unique kind of flight.

All true. Since the prop was close to the same area and (supposedly) similar pitch, the new prop did pick up a lot of thrust. For the carb, it's just a little hi-low Walbro. No jets to change, but I did richen it 1/4 turn.

@@AveryFlies I have a lot of experience with Powered Parachutes (and hence, props and engines). Have been flying them for 24 years and have literally owned dozens. Props can make a HUGE difference. Even props that are supposedly the same pitch can vary greatly (because of their design). The key to optimal performance is to first find out at what RPM your engine makes its peak horsepower. Most make their peak hp well before the "max rpm" and in fact tail off between "peak" and "max". Then, you want to select a prop that is pitched to max your engine out where it is making it's peak amount of horsepower. That should give you the maximum amount of thrust. I'll also point out that there is a direct correlation between your engine speed and your EGT (exhaust gas temperature). If you are under-propped (RPM too high at max throttle) then your exhaust gas temps will soar (which can melt pistons). We run EGT gages on our powerchute engines, and if my EGT is running too high (with the carb properly jetted), adding a little pitch to the prop (we run adjustable pitch props) will bring the EGT down. Anyway, very interesting video, and it was neat to see that you got it in the air. Yes, tuned pipes can add a LOT of horsepower. I bet if you went with a slightly taller pitch on your prop (now that you have the extra hp to push it) you would get even MORE thrust. (when the jet ski guys add a tuned pipe, they always add a higher pitched impeller to take advantage of the extra hp). Good luck and keep flying!

RPM does not correlate to thrust, higher RPM on proped engines can actually equal less thrust.

@@dracolyth yyyyes,...at a certain mach number of tip speed... but I am not hitting that. You can read through my previous 5-10 replies on this subject. I welcome you to do the math on a 32" prop spinning at 6000 RPM. It's less than the performance-robbing mach 0.92.

I was actually thinking the same thing. The higher rpm prop may have more quick torque, but will sacrifice thrust. Went through this on a boat as well.

right .. I'm surprised he didn't seize it ... I build racing kart motors, ring gap is super critical when installing a new ring. Very little power is lost via ring gap ... power loss usually results form aa ring warping and no longer contacting all the cylinder bore .. which can be visually seen with a light when squaring up a ring in the bore, if it ain't warped, run it. Alternatively, compression test it.

​@@KrustyKlowna

Hadn't thought of that, good point

So I've been told. Still, noticably more compression with the new rings, so I'll take it.

🤣 I'm getting rid of that foot angle, won't happen again. I don't know what you think you saw, cause I didn't see it! Was not commando for the record haha

The engine is proven, there are a lot of people flying on them, so I don't know that I'd call it junk per say... But it's definitely low quality.

@@AveryFlies maybe a little harsh, but that’s awesome you got it running really well. Big kudos to you my dude.

$2500 is junk? Must be nice living your life.

Good to know In the future, thanks. All the RC guys swear by Bowman rings in this motor so I think I'm in the clear but I'll be sure to do that next time

@@AveryFlies To be honest if lots of people have already used these rings you are unlikely to have a problem. It is however a very common practice in performance engine circles to check your ring gaps before installing them. Of course that assumes you know what the gap should be in the first place...

@@LesNewell happy to hear that. I will be more cautious in the future. Thanks for the info! Every day is a learning experience!

Thanks dude, I am 54 and now know why rings have gaps, and the gap distance is important, I have learned something new today.

Well it flies, so I think so

You know, I'm not sure, but with a small 1 gallon tank it's probably limited to time more than thrust. I would guess 2000-3000 feet above ground.

🤷 $15 drill bit set on Amazon go brrrr

Come on down! Winston Salem NC!

Every paramotor flight has the chance to turn into free flight. If you don't live near a good launch point, I would say go for motoring. Paramotor wings are often just paraglider wings with trims. If you get a motor wing, you can soar with it, it might not be as efficient but it'll still fly. I really like the gravity Xcend I used in this video, it's very affordable. The ozone Mojo (my other wing) is also a good start, a little more sluggish. Ive heard good things about the dudek universal 1.1 as well.

Absolutely!

Glad you liked it!

Sorry to hear that, I will turn them on if I can figure it out.

Thanks! I'm in mid-western North Carolina
