Is this guy legit?

So I see they’ve come out with a 200cc but it’s hard to find any information about it.
Dle 200.
There are a couple of videos on YouTube of people using them. I’d post a link, but that is hard to do with my p

I personally wouldn’t use a dle200. It is pretty close in cost and weight to a vittorazi moster or a minari 200cc. The advantages with the engines I just stated is that they have more power and they are made by a companies known for making quality and reliable engines(not made in china) The final reason I would choose a different engine is that I wouldn’t want to wait a month every time the engine breaks down and you need to order stuff out of china.(if you can even find them)

The reason I can see using a DLE170 is that it has a much lower weight, much better known performance and reliability characteristics, parts and accessories are way more available in the US, and it costs half of a dle200.

Thank you for your replies. I saw one advertised on Ali whatever it’s called for 2100 us. The water cooled version is 2900, I’ve never seen a mostar for less than 4000. I don’t know how much I could trust the website, so you may be right. It shows the 170 for just over 1000.

hello, i have been flying a DLE 200 since 2014. under the video i youtube you can find a link to my facebook page. there is a report about it.(you have to scroll down in facebook until you find the report.) i have only cleaned the carburetor once since 2014 otherwise no service was necessary. In short, the dle 200 is a pure “work machine” that was designed perfectly. the only thing that bothers me is that it is as loud as the moster 185. Due to the lower speed compared to other similar ppg engines, the del 200 has a much longer lifespan of the ball bearings and pistons, etc. I currently fly the propeller from the moster 185 with it. This fits perfect. it turns the propeller around 120 rpm less than the moster. that is around 65 kg static thrust.

i fly it with aspen 2 stroke mix. not with gasoline.

It looks awesome! You’ve created a beautiful machine there. I’M not tech minded enough to understand all of the description, but I understand enough to see that you have put a lot of love into the design.
Great work.

Well, I would listen to My. “Bratwurst” he knows what he is talking about and unlike me me has actually tested it.

A question for you bratwurst, what elevation the thrust testing was done and with what prop?

Can I ask how does one determine the right size of electric motor?

It really depends on the prop size and desired rpm. Bratwurst knows a lot more than I do, but as a general rule of thumb you want the motor kv multiplied by the battery voltage (no load rpm) to be about 25% higher than your desired prop speed.

For example the SP140 has a 40kv motor(mad m50) and a 24s battery with an average of about 88.8v. This equates to a no load rpm of around 3500 rpm or with a prop around 2850 rpm. On the other hand for a low rpm prop, you may desire a 35kv motor with a 24s battery to give a final rpm closer to 2300. Or for lower voltages like a 15s battery you would probably want between a 65 and 55kv motor for a 130cm prop.

There are also power requirements that you also need. If you want to use it for thermaling, you will probably need around 7 kw continuous power with maybe 12kw peak for a motor that swings a large prop. On the other hand, if you plan to fly this like a normal paramotor you may need more than 15 kw constant power with over 20 kw peak power.

Some suggestions: look into motors made by a company called “Mad motors”. They are good quality, good performance, and have a good price. Because of their great price to quality ratio they are used exclusively by openppg both on the x4 and sp140. Or if you have a lot of money I would recommend looking into “Hacker motors”. They are much higher quality than Mad motors and will perform better, but they will cost you a lot more.

I apologize for all the dumb questions.

Thank you for your concise explanations.

At this point, asking questions is all I can afford to do so I am trying to determine which path would be the most realistic for me to try.

I am also wondering if getting 4 of these would be doable (for me that is):

hi, i did my tests at 400 meters above sea level. temperature 20 degrees celsius and relative humidity at 60-70% air pressure average value. Propeller is the original e-prop which is only produced for vitorrazie exclusively. he has a lot of pitch at the root that cools the cylinder of the moster well. that also fits perfectly with the dle. the dle is not as powerful as the moster. but due to the low speed on the prop, he has enough torque for the e props. At the beginning I used a 3-blade helix which I shortened step by step in 1 cm increments until the engine had almost reached the maximum speed, it finally had 122 cm. since the diameter was only 122, the thrust was also around 63 to 64kg. the eprops is much lighter so better for food drag or funflighst because it turns up faster. the dle is very linear when accelerating because it does not resonate as intensely as otherwise ppg engines.

a few empirical values.

applies to pilot 85 kg, wing EN-B 26 -28 m2
start at 300 msl to 1200 msl

standard flights in the range 150 to 1500 meters above ground.

propeller 125-130 cm

  1. for thermal flying with pod harness: start 9-10 kilowatts, easy climb 1 m / sec 6-7 kilowatts. level flight 3.2 -3.6 kilowatts

  2. Easy training and allday eppg: start 9-10 kilowatts, easy climb and trimmer open level flight, fun flights, food drags etc. 6-8 kilowatts. leveling trimmer closed around 4 kilowatts.

  3. standard eppg, small xc flying: start 10 -11 kilowatts, playground flying, soft pylon, fun 6-9 kilowatts. level flight around 4 to 4.5 kilowatts

  4. power eppg: start 12-14 kilowatts, playground, powerclimping, pylon 8-14 kilowatts. speed cruising trimmers open 6 -10 kilowatts depends on the wing. minium level 4.5 kilowatts

  5. Light Trike (max takeoff 150 kg): start 12-14 kilowatts, miniumum level 5.5 kilowatts (130 cm props).

trikes need wings 30 -32 m2!

6.power trike (max takeoff 220 kg): start 18 kilowatts, minimum 6-7 kilowatts (150cm props)

the whole thing varies in the range of up to 10% up and down depending on the wing, flight style and frame, cage etc.

I know of very few ducted fans that could create a usable amount of thrust with only 4 of them. This is one of them:

The manufacturer claims it will make 56.8 pounds of thrust. The problem is that it would take 30kw of power with 2 of these to make 100 pounds of thrust. For comparison it only takes roughly 13kw of power to make the same thrust with a properly built single prop unit.

I’m not sure what these guys used; but they do need more power for sure:

As others have said, it’s kind of noisy. I was kind of thinking that this sort of system might be
useful for training beginners if it were all mounted on a harness system.
Anyway, I bee broker than broke, so I won’t be trying it any time soon.

over 100 mph its funny with impellers.

for eppg not usefull.
