DIY Su-57 Felon with Ducted Fan or Pusher Prop : Which One is Better?

[@AEROERGO]

You know what i like of your videos?, the fact that you show how hard could be sometimes the path from the maiden flight to the final plane configuration. Many channels show just how was build it and then flying flawlessly. So many beginners thought that scratchbuild and fly is very easy, when actually is not. Thanks a lot for this video!

[@JuliusPerdana]

hahaha thanks, on this video there are 7 flights with 6 crashes, actually it was 8 flights, all 7 ended up in crash lol. I assumed landing on water is not crashing lol

Great work, really good. But pls dont respect anithing russian, this terrorists state bombs civil people. This is a murderers aircraft. Not for defence. One day they can come to yours home too. Hope we will stand and win. Greetings from Ukraine!

[@dipereira0123]

@@JuliusPerdana Dont be too hard on yourself! those wasnt crashes, remember, Every landing where you walk out of the plane is a good landing, if the plane can still be used later then its a great landing so it was a great landing x6 ;D

[@videorowtv5198]

Hi, it's called a leading edge flap, it helps direct air over the wing during high angle of attack so the plane doesn't stall. Also very nice build!

[@مقارنات_الجيوش]

but nice aircraft

[@onyxfinger7431]

nope, that's a levcon - leading edge vortex controller

[@nmakala9]

It is not quite that. The Russians call them Levcons, and their objective to control the formation wing root vortices

[@ШАНс-в1о]

Нет, мы не называем их «левкон». Это отклоняемая кромка крыла.

[@richardkan8499]

Unbelievable how tough your model is - still flying after so many crashes. I should try building mine out of foam to be this survivable!

[@JuliusPerdana]

thank you, packing tapes hold it together, for me I'm surprised on how durable the plastic primer is, not any single chipping paint.

[@richardkan8499]

Am also so impressed that you use parcel tape. Could this become brittle with age? Like it dries out and crumbles?

[@rcbinchicken]

@@richardkan8499 It depends on the brand. I have had some packing tapes go a little bit brittle with age, and others completely unaffected. Funnily enough, the worst for that is the fibreglass-strand-reinforced packing tape. The adhesive they use turns yellow and crystalline with UV exposure, and loses all its stickiness.

[@johnwalsh1879]

Fantastic jet. You just keep going fair play bud. Well done

[@JuliusPerdana]

Thanks 👍

[@garlopa1336]

Hi Julius, great job, my congratulations, the pitch problem is because the EDF's thrust is parallel to the flight line, if you look at the real plane the exhaust engines point upwards, note that for example in the F -15 also points upwards, the incidence of the EDF is: if the EDF is below the wing the exhaust points downwards, if the EDF is parallel or above the wing the exhaust points upwards, it is like the incidence of the engines in pusher planes, regards!

[@EDF_FANatic]

Wish I could build like that. That's a gorgeous su 57!

[@davehenry-hl5mt]

I just knew that the prop version was going to be perfect 👌 Awesome built

[@rodinvillarosa2924]

Great model sir. Built my own Su57 foamie using RCPowers plan but modified to run on twin motor tail pusher, suggest you rebuild yours using twin motor with differential thrust for a strong yaw authority.

[@henvan8737]

What a great effort to keep working and achieve reasonably stable flight. Great model.

[@Animboyexe]

now we can say that there are 12 SU 57s in this world which means, theres an entire squadron of them

[@JuliusPerdana]

Lol

[@Animboyexe]

@@JuliusPerdana indeed

[@juliap.5375]

Where did you get this numbers? 😂 Amount of jets is classified and unknown. Before 2014 when Russia increased level of security, country produced by 100 different jets per year only for internal usage (and dozens for foreigners). It is public numbers. According to Soviet experience, it means in 2-3 times more produced secretly. So, at least 200 jets per year. From that times Russia increased amount of production. How do we know this? Factories nowadays working in 2 and some even 3 shifts (24/7 non stop). It means production increased in 2-3 times. So, now is produced at least 400 jets per year. New factory for Su-57 launched in 2019. So, according to basic logic, there are at least several dozens or more likely few hundreds of Su-57. You reminded West which year ago told that Russia have cruise missiles only for 1-2 month of usage. Surprise, Russia already used more than West produced for last 20 years and still use almost each day. If you forgot, in Russia all military factories are state owned, country have all resources (from energy to metals) in unlimited amount, it means for Russia weapons de facto cost nothing. And production is limited only by amount of workers. Are you forgot how europeans failed back in 1940s when attacked Russia. They also was sure, in Russia no weapons. Surprise, Russia had and then produced more than entirely huge Europe.

Kalau mas ingat saya juga beli mika bening satu gulung dengan panjang 1,5 meter yang pasti sangat ribet untuk dikirim. Melihat video mas Julius saya jadi ingin membuat papercraft lagi, tapi mungkin masih nanti karena tidak banyak waktu untuk hobi hehe. Sukses dan sehat selalu untuk mas Julius dan keluarga!

[@Nameless69418]

The plane keeps diving down can mitigated with thrust vectoring. This can be done by adjusting the direction of the nozzle thrust. This is also the main reason why the real su57 is so manuvarable. If u can add more servos to change the thrust direction, the plane will be much more stable.

[@Jay-zc7iq]

I think the droop flap is used to change the air going into the engine much like the moveable intake on the F-15.

[@BuceGar]

Nice build! Simple and effective. I like it.

[@JuliusPerdana]

Thanks! 👍

[@HGFHY]

Cool. I made a project of a hotspot with a wingspan of 1.10m. my first motorization was a 64m edf with 12 pas and 2200 4s battery. I removed the turbine and put a 1700kv engine next to a 3530. It improved the flight by 60%. but it was low speed. I'm going to put a 3536 of 1200kv and a 7x4 apc propeller to see if it improves.

[@gke3800]

I suggest you increase the pitch on the prop to 6.

[@everythingrc5652]

really nice build the only bit which might confuse people is the foamboard is what flite test use which has paper on each side and depron is what you mostly use which doesn't have paper

[@Jay-zc7iq]

Yes , I use foam. Board with the paper for his models , I find if I use the paper stuff rubbing it off prior to paint or decoration works out just as good I’ve made several of his now and might go to balsa on some of his builds as they do fly well

[@everythingrc5652]

@@Jay-zc7iq yeah as I live in the UK most of the foam board isn't very good and hard to remove the paper so I can't really do it

[@Jay-zc7iq]

@@everythingrc5652 a tip I use is to use a cloth or a very fine foam sanding block you can get most places wet it with a small bowl rub the paper and comes off nice leaving a very smooth and very good finish I use warm water too if I want to bend or shape stuff but works great

[@everythingrc5652]

@@Jay-zc7iq alright thanks I've done it before but I'll try again. I use 5mm xps foam which is good but has lots of little holes in it which means tape won't stick to it so I can't do tight curves as I can't seem to find any better cheap stuff in the UK

Try putting the battery weight in the middle of the plane to level out the weight. The batteries are probably the cause of the nose/front to be heavy.

заглянем на минутку в историю создания су 57 начиная от су 27. проблема в том что его планер изначально нестабилен и очень сверхманевренный, для обеспечения стабилизации была создана программа для обеспечения нормальной управляемости за счёт управления плоскостями. без неё его будет мотать, так как он изначально был случайно, а затем специально создан таким. планер сам можно сделать, а вот чтобы он нормально летел это уже заморочки с управлением и программами

Hey Julius I was gonna ask you during your live feed how would you go about painting a model using dollar tree foamboard it has paper on both sides. This plane looks sick im making a f22 raptor for myself now and this would be the next one

[@JuliusPerdana]

Can you apply paint on the brown paper, or you peel them off afterwards?

[@Dugar1]

I can peel the paper off and use you paper covering method. Painting the paper that already on the foamboard causes it to bubble and looks horrible. Another question could I use elmers glue or modge podge for the paper covering method

to your question: those are not canards. more likely droop flaps as you said. it doesnt behave like a canard either, it more likely bites the airflow
