AliExpress paramotor: Upgrades and First Flight! | Avery Flies

The AliExpress paramotor flies!
REQUIRED fixes BEFORE FLYING: • AliExpress Paramotor R...
Assembly and first impressions: • Ali Express paramotor!...
I tried to fly it a while ago, but the propeller was the biggest thing holding me back. So I changed the exhaust, piston rings, and the propeller to increase power 25% over stock and finally push me into the air. This video also doubles as my review of the Gravity Paraglider Xcend EN-A wing, which I picked up specifically for this motor. Together, they represent a shockingly cheap $5500 brand new paramotor rig. Now that I have the full picture, I can say with certainty that this is NOT a good first paramotor. But if you're light weight, looking for a project and you want something small, then maybe it's worth considering.
I really like the Xcend wing. Get one from glider sports here: glidersports.com/shop/gravity...
If the low power and amount of problems I've had did not scare you off, you can buy the paramotor here: www.aliexpress.com/item/32568...
The exhaust can be bought from this gentleman, who also builds and sells DLE170 paramotors: / dle170-paramotor-thail...
Oh, and the propeller came from amazon, if anyone needs one you can find it here: amzn.to/3aYDEgO

So yeah, it flies. But a ton of time and money went into making it fly. Most importantly, there are 11 modifications I had to make before I considered it safe to use. Please watch this video before considering buying one of these: kzbin.info/www/bejne/mKSyqqGjgNVjgaM

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.

Brilliant I enjoyed that made my day - stay safe

[@muddyudders]

The expansion chamber allows for scavenging the cylinders and most importantly adds back pulses which act like a supercharger and force unburnt fuel from the exhaust into the cylinders before the port is blocked.

[@raymondo162]

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

[@muddyudders]

@@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?

[@AveryFlies]

They do.

[@calthorp]

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.

[@jonathanelam2331]

Lol… you took the words outta my mouth! That would make a sick mid day thermal machine!!!! My rush 5 and that looks funner that my nitro / rush 5 combo fir hooking some lift. Very cool!

[@AveryFlies]

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.

[@BushcraftTexas]

@@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!!!

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

[@E1320_]

Indexing the spark plugs is a good idea on a 2 stroke also, you get a little more power and your less likely to foul the plug.

[@secondhandlyon2603]

The only thing I would have done differently is to put the new rings in the cylinder, square it up with the piston and check the gap. Cool video.

[@KrustyKlown]

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.

Great vid man!

[@SanjanaRanasingha]

Very informative video subscribed!

[@ArionRaine]

Tuned exhaust is the single most beneficial thing you can do to a 2 stroke. Second being proper ignition timing/advance curve. (outside of more drastic things that may or may not be able to be done depending on the engine)

[@fredpinczuk7352]

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.

[@ArionRaine]

@@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.

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

[@krisraps]

What A Cool Device And Mods.

[@porticojunction]

Nice. 2 strokes are so weird, like parts got left out. A proper chambered exhaust makes a big difference in useful power at the right rpm. There is actually quite a science to it. The rings might have been ok but what an easy swap. Glad it works!

[@noname-wo9yy]

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

[@georgesadler7830]

Thank you for the video.

[@thebeerinnandrewmckenna2655]

I fly rc, the reason they put oil in the engine, is to stop them ciezing or being hard to turn after long storage. I have glow engines, some people do it to those as well

[@bradbrown2168]

I have an Eden 3 24m and an old sky cruiser w top 80. Could it buy just the engine and components to retrofit on my frame? Would a top 80 sized prop be too taxing on this engine?

[@AveryFlies]

The only way a propeller in the 40-50" range would work on the DLE 170 is if, like the top 80, you had a gear reduction. A 1:2.5 or so would let you spin a bigger prop slower and most likely make more thrust. Sadly no gear reduction exists for this engine. It's a shame too, because it could make atom80 levels of thrust while being lighter and cheaper. If you want a budget engine replacement, look at the DLE200. It is belt driven like a moster and purpose built for paramotor use.

[@byron3373]

When installing a ring there is a way to measure the gap inside the the cylinder and if its to small the gap needs to be made wider because it can cause engine damage if the gap is to small

[@ForeverNeverwhere1]

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

[@jwoodyr1]

Did you heat cycle / break in the engine before and after you changed the rings and before you did your power pulls? Thanks.

[@AveryFlies]

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.

[@brettbull5238]

Did you time the blade mounting with top dead center I haven't gotten all the way through the video yet

[@AveryFlies]

I did not, no. I saw no reference of that in the manual for the engine or the forums I browsed

[@akbarshoed]

Well done!!

[@ionutz89ful]

I want to buy my first wing, not sure if I should try to paramotor or free flight, because it might encounter a problem with the engine and I might struggle with it... but If I would think to try a paramotor first any recommendations for the first wing? thanks.

[@AveryFlies]

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.

[@coolguy21420]

This video is so awesome! I have always wanted to do this. How much training is needed? Can you point me to some resources? I am a H2 hang glide pilot so I have some aviation training. This type of flying is really something I want to do! Thanks for the video!

[@GDFred88]

[@AveryFlies]

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.

[@ferrumignis]

Adding an expansion chamber can significantly weaken the mixture on a two stroke, keep an eye on the plug colour!

[@RwP223]

Not a one up, just another pathway I took was the skycruiser frame + lightly used top 80 + new apco SLT harness was $3000, but i had to assemble it...it being a pile of parts no instructions. After 50 flights I have had no build issues except optimizing the thrust angle with motor mount shims. Maybe some of you arent high conscientious mechanics who would be able to properly assemble a pile of parts with the mechanical foresight and basic engineering knowledge like gussets or the concept of strain relief, so then you buy this thing.

[@mochamon]

Great video. Want one of those myself but at 200lbs don’t if it would work. Any idea what kind of thrust it has after the modifications?

[@AveryFlies]

I don't have a way of measuring it, sorry. The falcon propeller says it should be about 90 lbs of thrust. It's enough for me, but I wouldn't consider it if you weigh over 180

[@jasmijnariel]

A diet could work😉

[@mochamon]

Thanks for the info. Like the diet idea, but I am too lazy. Lol.

[@mrbmp09]

The expansion chamber added a lot more power than you think. Swap the exhaust back and you will see a huge decrease in thrust.

[@wayneo9783]

wondering what was your takeoff weight with that 28 wing?

Great video!!!!! I've seen pther videos about this parmpotor and most of the buyers fly it out of the box with no upgrades. Why didn't yours take you of the ground out of the box? Is it diferent than other DLE paramotors? I was thinking on buying one, but after seeing your video Im not so sure

[@AveryFlies]

I tried to fly it stock, see the first 30 seconds of the video... My propeller was crap. If I had changed the prop it would've flown stock. I didn't know the prop was the problem at first and went to engine tweaking. If you buy one, don't get it with the propeller and source your own.

@@AveryFlies Thank you very much for your answer ;)

[@AveryFlies]

Always!

[@rabcameron1676]

So…. After changing the piston rings, what was the ring end gap…?

[@AveryFlies]

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.

[@bradbrown2168]

Very cool! Run time? Can you retrofit a larger fuel tank?

[@AveryFlies]

Flies for about an hour on the one gallon. Bigger tank is a maybe. The upgraded exhaust takes up a lot of room.

[@mitchell5828]

Do you know what the pitch was on the original 32" propeller?

[@AveryFlies]

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.

[@mitchell5828]

About a gallon an hour. Nothing out of the ordinary. It would be far lower if I could get a prop redrive and spin a more efficient blade.

[@JohnnyFaber]

So how much did the mods cost and what was the time investment to get this off the ground? I bet you ended up spending more than a good used unit would end up costing.

[@AveryFlies]

The exhaust and prop brought the total with tax and shipping to around $3200. Maybe 3-4 hours worth of tweaks and upgrades. I browse the classifieds regularly, I haven't seen an atom80 powered unit for that cheap.

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

Best wire the new expansion chamber and muffler to the frame so if it cracks it doesn’t go rearward into the prop!

[@AveryFlies]

Good point. I'd probably need to weld on small tabs to tie wire to. It's all one piece, unlike a moster exhaust it doesn't have spring loaded joints. I feel like the fact the exhaust system is only attached at the engine block means it moves with the motor and has a lower chance of cracking. I will look into wiring though, you have a good point.

Soon as I saw the silencer length and how far past the expansion chamber it was I knew it was gonna be quieter. Still too loud for me, I'd go electric even though it's a bigger pita, expense with less range.

[@LesNewell]

You need to be very careful when playing with ring gaps. The rings expand as they get hot. If the two ends touch they will seize the engine or at the very least damage the piston or bore. As you found out the gap doesn't make much difference to power. A tighter gap should improve starting and give a very small power gain but I'm not sure it's worth the effort and risk. It's a bit late now but the correct thing to do is to fit the rings in the bore without the piston then measure the gap. If it's too tight you can file the ends with a fine file.

[@AveryFlies]

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

[@LesNewell]

@@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...

Without going crazy on mods, the 32x10 or 32x12 carbon fiber prop is the best thrust option for this engine. Falcon props has tested this.

[@jameshatton4211]

@@AveryFlies oh I'm aware of prop science from drones. For me more blades =quieter Harsher pitch for more blades to equalise thrust; more blades causes more aerodynamic drag so you will need to add more throttle and potentially shorten the range? But range can be increased with a bigger fuel tank and some more precise tuning (possibly a different card and jetting?) Having a really decent muffler system as well and you could potentially not piss as many people of?

[@gkess7106]

The sudden rise in perceived compression was no doubt due to the oil bath you had given the piston rings. See if you can purchase rings that actually overlap. They make them for cars. You’re going to see your best performance by having a higher compression ratio, larger carburetor, and better exhaust.

[@AveryFlies]

Other viewers have mentioned that as well. everyone in the RC community swears these rings are as good as it gets though, and it does fly, so that's where I'm leaving them.

Hi, i bought same engine online, so i will have to change exhaust or not, my weight is 76kg. Can you make video on how you did wiring and what battery you use for self starter.

[@AveryFlies]

You weigh the same as me! You probably don't NEED the exhaust, but it makes more power and sounds better with it, so I would get it. You can message the manufacturer here: facebook.com/Dle170-Paramotor-Thailand-104153761733715/ The battery wire I just made longer so the battery could fit in the pocket. kzbin.info/www/bejne/mKSyqqGjgNVjgaM And the battery I'm using is a 6s 22.2v 1550 mah LiPo for a drone. www.amazon.com/1550mAh-Quadcopter-Helicopter-Airplane-Multi-Motor/dp/B07JQ92RKP/

@@AveryFlies Interesting, the guy in Thailand selling the tuned pipe exhaust seems to have an even cheaper paramotor kit than the Aliexpress. And, based on how much effort you went through to make your paramotor safe, I wonder if the quality might be better too?

[@GDFred88]

Pretty cool. I live on an island in the Caribbean with constant 10-15mph winds. I'm looking for a small, lightweight paramotor I can carry on a commercial airplane. A couple of questions if you would. 1. How much total are you invested in this? Can you give a break down? 2. It weighs 40lb which is great. What's the combined displacement on the engine? 3. Do you have any pictures of it with the hoop broken down? Would it fit in a normal sized suitcase? Thanks in advance.

[@AveryFlies]

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.

[@GDFred88]

@@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?

[@AveryFlies]

@@GDFred88 You can see the original box in the first minute of my first impressions video: kzbin.info/www/bejne/opKzi4Wgn52Ehrs 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: kzbin.info/www/bejne/mKSyqqGjgNVjgaM 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.

[@pauleggington]

Is RPM a good gauge of power?

[@AveryFlies]

In this case, it's the only one I have. Since it's a 2-stroke, it has a fairly narrow power band, and the closer you can get to it (mid 6000's) the more horsepower the engine is making. When changing propellers, that doesn't necessarily mean more thrust (putting a 20" prop would make it spin faster of course, but with less area you absorb less HP into the prop) but in this case, since the new prop was near the same area as the old one, 25% increased RPM was a gauge of significantly more thrust. Obviously, on the same propeller, the exhaust and piston ring upgrades increasing RPM would net an increase of thrust, since the same prop spinning faster does equal more power (until the prop tip approaches supersonic) (In this case, @6500 RPM, the 32" prop tip travels 902.75 feet/second = Mach 0.8. Max recommended for RC applications I've read is 0.92. We really only tickled 6000 RPM so we're good.)

[@Dr.JustIsWrong]

Are the propellers opposite pitch?

[@AveryFlies]

If I understand you correctly, yes. The DLE170 spins counter-clockwise, so this needed a pusher propeller that is reverse pitch from the typical dle170 prop

[@Dr.JustIsWrong]

@@AveryFlies oh, okay. I thought I was going cross eyed

[@richardwallinger1683]

the air filter and old silencer would not assist the two stroke power delivery .

[@alanhodgson8527]

What is the maximum height that you can go, if you could let me know please. I hope to see more of your videos. Take care sir. Alan

[@AveryFlies]

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.

[@doraexplora9046]

Tucker Gott is doing the same thing and he changed the carabiner's as they were no-name brand. The main thing I noticed with your setup is that you didn't tune the engine. I felt like it had lag on acceleration, and didn't make as much power as it could. Tucker tuned the engine, I think he got a lot more power out of it. But the prop seems to be a major change, but also I like the ring mod. Tucker also changed out the entire fuel line system because the primer bulb was restricting fuel flow.

[@AveryFlies]

Yes, I've been following his exploits. My primer bulb worked, but my fuel line was PVC, so I swapped that. I didn't show it on camera but I did tweak the carb a lot, and chose to run slightly rich intentionally.

[@doraexplora9046]

@@AveryFlies I would have included that tid-bit. That's the detail people want to know. I'm really curious if this all works out. You did some pretty interesting mods. The bulb is just a marine outboard item. that exhaust was amazing. I feel there is a lot of parts available for that engine. So it will be interesting to see what Mr. Gott comes up with. Top channel BTW. Subbed.

[@DoRC]

The main reason the compression felt so much higher was because the cylinders were full of oil. This will artificially increase the compression significantly.

[@AveryFlies]

Hadn't thought of that, good point
