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

I made this Sukhoi because I already made an F-22 Raptor plans, because I think it would be interesting if I made its rival too which is Sukhoi Su-57 Felon or in Russia known as T-50 PAK FA. This model is not design specifically for neither EDF or pusher prop, I just design the model airfame that can be built with 5-6mm foam board or depron or polyfoam, without any propulsion mounting design. You have to figure out yourself, but you can see on the build video how I install a single 70mm EDF on center between the two exhaust. For this setup I use FMS 12 blades 6S 70mm EDF, with 2.6 kg thrust with 80A ESC and 6S 2200mAh Lipo, I think it's more than enough than the weight itself. I also convert it from EDF to pusher prop using DXW 3536 1200kv brushless motor, 10 inch prop, 50A ESC and 3S 2200 mAh Lipo. Both perform well, while there's some problem in the beginning, you can see it on the build video on KZbin.

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

[@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.

[@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!

[@مقارناتالجيوش]

but nice aircraft

[@onyxfinger7431]

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

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

[@JuliusPerdana]

[@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.

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

[@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!

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

@@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

[@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.

[@fdhlmr]

Mas Julius apa kabar? Saya lihat mas Julius semakin sukses dan besar. Saya dari Solo dan tahun 2012 silam pernah beli satu set alat papercraft dari website paper-replika. 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!

[@Airid-eb6wz]

Awesome bro❤❤❤❤❤

[@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.

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
