DIY F-8 Crusader RC Jet with Ducted Fan and Pusher Prop : Which One is Better
Vložit
- čas přidán 5. 08. 2024
- In this video we're going to build from scratch and fly a legendary jet fighter, the F-8 Crusader
I will also test it using pusher prop and EDF for the propulsion system
we'll see which one is better.
I'll be relying on trusty 5mm Depron foam as the main material. Don't worry, I've prepared downloadable PDF plans on my website in both A4 and A0 sizes for your convenience. And the best part? This amazing F-8 Crusader will be brought to life by the talented Roy using my plans!
I design the plans with Blender and Pepakura Designer. This model is a bit bigger in scale than my other jets. Because I have to make sure the wing surface area is big enough and I just love bigger models, it can fly slow.

You have reached the highest level of professionalism and art.
This was fantastic!! My favorite part was the sound of laughter and fun among a group of friends enjoying the hobby. I am very inspired.
Awesome! Thank you!
You are a true craftsman, builder and RC pilot. I enjoy everything you build from scratch. Well done
Very successful. The Crusader is also not done very often. Nice!
This is truly what a plane enthusiast can do. Mind blowing job👍👍👍💯💯💯
Awesome build. The Crusader and the Vigilante are my two favorite military planes of all time. Everything about the Crusader looks so cool.
The RA-5C Vigilante is my all-time favorite!
you never disappoint ! Well done !
Great machine and "whoosh..." jet sound....! 👍👍👍👍
I wish the prop pusher was better cause cheaper and simple but the edf principle and its noise, it really makes this big dangerous army jet completely alive !
Thanks for showing many building details, youngest don't know how lucky they are to access channels like yours.
One of many Navy and Marine fighter planes from back of the day.
Thank you for posting.
Beautiful plane!
Thanks, one of my favorite jet
This is truly what a plane enthusiast can do. Mind blowing job 🤯🤯
Thoroughly enjoyed this! Greetings from UTAH!
Awesome! Thank you!
That’s beautiful! Love the edf
thanks mate
Another amazing plane!
I'm learning lots watching your videos, lots of excellent engineering and detail, seriously excellent work 👍
thanks for watching my video
Sir! You have certainly improved your channel as if it needed it. Having assistance, I’m sure has helped your efficiency. This is a fine model. My vote is for the prop power. Simple, lighter, less expensive 👍
I only wish I had this kind of skills! Great job!
Once again. Look amazing sound grate.
Thanks again!
Definitely well done! Thanks
Adding the ducted fan made the plane... very nice.
Your finishing touches are legendary!
Great work! Your F-8 looks and flies so well. I use Adams Readi-board for models. It's 4.5mm EPS foam with paper on each side I think or 5mm thick. Instead of cutting multiple slices on the inside of the fuselage to bend it into a curve, I remove the paper on the inner side. I've been doing that, and then bending the piece on an edge. On some models I remove the paper on the outer surface as well once it's complete then recover with newspaper and glue. It can then be painted. I haven't added heat to help but maybe I will in the future.
Fantastic. Your designs are getting better and better.
This is a an awesome achievement Julius. Simply stunning. It looks very nice and appears to fly very well. I am amazed at your skill!
I really need to make one of your RC planes! I’ve built several of your paper models and they’re always fantastic. These look awesome, so much more detailed than manufactured RC planes!
Thank you very much!
I got no words........simply,AWESOME!!!!!!
Beautiful workmanship
Looks amazing.
Você não imagina o quanto eu estava ansioso por ver esse excelente projeto ser tranformado nesse também excelente video. Parabéns do Brasil.
I am so amazed at your skills!
Good job ! The EDF sounds really great! Congratulations my friend! Best Regards Martin / Berlin Germany 😉
Great Julius as always wonderful work
Hi Julius ...
Your work is so amazing.
I am a big fan of you.
You teach it in incredible way.
Genius , awesome skills and craftsmanship 😮
Excellent craftsmanship!!!😊😊😊
Excellent work!
Very good my friend.
I have waited a month for that I'm so happy you finally post it
Buatan om Jul itu emang ga ada obatnya
Ibarat apotek tutup...joos tenan pisan
Awesome build ❤
Cool plane 😎
Fantastic as always, greetings
Wonderful build of one of my favorite planes.
thanks mine too
Nice Build and Flight.
Greets from Austria
Woahhh, perfect Work👍👍👍👍 perfect landing, congrats
Amazing model, congratulations.
greetings from Mexico.
awesome video! very creative uncle
Great as usual 🤩😍👍🏻👌🏻
Wow man just found your channel. What works of art you make sir and they look like they fly great.
Keren sekali om, jadi pengen belajar tentang rc pesawat
Hey Julius awesome build as always keep up the great work.
thanks
Belíssimo trabalho Julius parabéns muito bom
I didn´t finish yet but Roy must show us how to make that liitle iron! looks neat! 😃
good idea, I will make a video about that
@@JuliusPerdana great!, it will be a success for sure! - I will stay with the pusher version i think, i always prefer a lower wing loader. Cheers!!
Magnifique
Lulu the cat FTW!
I wish one day i could be part of the "builders for videos team" hehe. Specially if you made an Argentinian plane.
keren om... Salut ma om julius.. Karya nya bikin ngiler... 👍👍
Dude, youre a genius!
no I'm not, but thanks
Very good plane build bro👍👍👍
Excellent project Julius is a beautiful jet, I'm going to build it using the EDF system.
thanks, have fun
Yes!!! Finally some EDF success 🎉 nice job sir unfortunately I can’t build this one as I got a years worth of your planes to fly bird dog sat there berkik 3 and much more I’ll be tackling your A10 soon and I’ll get it to fly , thanks again sir 🙏
I am a big fan of your work and did try to modify your F-4 into the YRF-4E...I messed the nose section up ...tonthevpointbof embarrassment. But I shall try again health permitting. Such beautiful toys, you have become a master builder . I have seen much improvement over the years and increasing more difficult designs which you find simple answers to. Amazing take care.
Great flyer I think the edf is the way to go
This is a beautifully desing plane plan and an excellent executed job by Roy. Any chance that one day you would be doing the Noth American T-6 Texan trainer? Thank you very much Julius. Your channel is one of the most rewarding and constructive channels i have ever come across in CZcams. Keep up the great work. Greetings from Spain.
GJ!👏
thanks
fantástico el trabajo, lo difícil ,lo hace sencillo !! En hora buena
thank you
With EDF, there is much more happiness 🙂
Absolutely AMAZING! I'm going to make this one, let me know if you need the retractable 3d printed landing gear files.
First time I ever saw missiles on the side of the fuselage wow!
1950-60 was full of experiment in military aviation technology including this F-8 Crusader
It looks exactly like my Freewing 64mm F-8 Crusader! Just needs the refueling bulge on one side.
well done, as usual. Nice landings and the ducted fan sound!! Top! It looks, edf in that setup more power, than pusher, or?
6:30 what a skill!!
whats up Julius i love your videos and i've been wondering why you haven't been posting much but i'm glad to see you back now and i think the plane was much better with the brushless EDF motor even with those air ducts it made it sound just like a real jet
maybe there's something going on on CZcams algorithm, because I always post at least a video every month, buy yeah "I'm coming back" with more to come! Thanks to watch this vid
Sir I am Big fan of you
Wow this might be your best looking build yet! Beautiful!! 😄 And it flew great with both power systems. Although I always use props I must admit the EDF sound was incredible. One note, your CG was nose heavy because using a flying wing calculator does not take the horizontal stabilizer into account. One way around this would be to work out the CG of the wing with the calculator, then work out the CG for the H-stab as though it were a wing, and then work out the average CG by the proportion of the two areas. You should end up with a CG similar to your own calculation before, but a little further back. It won't matter this time, as you seem to have got it right with the "grass test" 😛 but maybe useful for future.
20% MAC = nose heavy, but 25% MAC = spot on
Nice job as always!
But why do you use a Y-wire to connect ailerons? You have a Jumper/Radiomaster radio with fully programmable channels. It will be easier to set position independently and make differential movement.
Cheers!
Thanks, my BetaFPV Elrs RX only has 5 channel
You keep coming up with beautiful models of beautiful subjects. I built your Stearman last year and it is a joy to fly. Since then I have your T2 nearly finished and am expecting it to be every bit as lovely as the Stearman. Just started work on your iconic DC3 this week when I spotted the Crusader. I'm going to need more foam! I have been finding with some practice, that the foam sheets and hot glue construction is a very satisfying build method.
Cómo siempre buen trabajo Julius pero también realice un proyecto de me 262 y también me bf 109 también desearte un feliz y exitoso año nuevo 👍🏽
Bagus
This model is really beautiful. Can you make a model of LCA Tejas.
Надо для EDF ещё побольше воздухозаборников вырезать.
Тяга тогда увеличится.
Can u make a glider like a discus? Love ur content would like to see you build one
Sir, you made me love the Crusader again! It seems like you made two airplanes, one with wheels and one without. How did you retract the gear on your flights?
Hi Julius, i need to buy a tx/rx equipment. Would you do recommend me a brand to buy. Thanks in advance
looks great! what do you think the effect will be if I put the motor for the pusher prop in the center of the wooden plate on the jet? do you think it will still be ok to fly like that? I would not intend to take off from the ground
it should be on the center
salam satu langit Bang Jul... dari dieng,, subcriber pemula yg sudah manula Bang Jul... ijin belajar
monggo om
Belleza ..Julius podrás en spanish Please cc..
Saludos
I am currently cutting out the paper stencils for this plane. I plan to use the 80 or 90mm edf. I will post of a video when I am finished.
Fantastic, have fun!
Om Julius bikin a4 Skyhawk pake edf 64mm dong😁 kayak di 16:13
Sir can i use styro foam instead of depron foam
Fantastic work, really enjoyed the video, lovely plane, where did you find the pilot 3d model? is available for download?
I bought it from Cults3D
What are you using to make the cheater holes for the edf?
3mm plywood
Where do you buy foam
What foam are you use
polyfoam/ depron foam/ foam board/ dollar tree foam board/ XPS foam/ KD foam board
I've been enjoying the Mirage 2000 and F-16 as slope soarers, and looking forward to building this one as my new sloper for 2024.
Very nice 👍 could you please tell me what cheat holes are, I've never heard that before 😊
cheat holes are made to maximized the air sucked by the ducted fan, because of obstacles like cables or other parts inside the air intake tube into the fan
🎉
✊🏻😊
please make us a video showing how you make the décors for your rc planes, or just give us a hint,.. please
Can you pls send me where you buy foam board. I want build your model t6a texan2. Pls.
I love this plane and you made so realistic. You have perfect hobby at home
What is that material board you use
Depron foam
