Oh, definitely. The sprag clutch is a lifesaver in case your RPM's fall off. Excellent work. Stay on it!
very good thank you
Вы удивительный человек! такой чистоплотный, порядочный! Удачи Вам!
It is a delight to admire your work so professional and thorough. I really enjoy your videos and the solutions to the challenges posed by this project. A hug from Spain from a model airplane enthusiast
Thank you :-)
nice job man.. I like the way you anchored the bearing .. With the freewheel I guess you can focus on autorotation instead of disengaging some sort of clutch system.
Thanks rob :-)
Just what the doctor ordered on a Saturday viewing pleasure. I’m getting excited for you as I see it getting closer. 👨✈️. Sorry. Didn’t have a helicopter emoji so I used airline pilot. Looks GREAT 😊
Thanks Bruce :-)
@@ultralighthelicopter where do you live in Ca
Beautiful work.
l'art de la mecanique par la simplicité et l'excellence ❣👍
Hallo Leute. Alles klar..?
Sehr geiles Projekt!!
Kleiner Tip: Zum Bearbeiten von Alu mal Spiritus als Kühl&Schmiermittel verwenden, Verklebt die Späne nicht und ergibt super Oberflächen..
Grüße aus'm Saarland
Danke für den Tipp
Sir super work but next time try to heat fly wheel which will make your job much more easier
Beautiful!!
superb work !
Vidio ini paling aku suka. Ada pengetahuan di dalam nya
Don't forget navigation light ,
And strob light .. can't wait to see it fly ..
By test flight I would like to have the Honor to visit ✌️
My opinion is two one way bearings would be wise. 3 pins will deform the race as it grips the rotor shaft.
Men te sigo desde que comenzaste en cero y te admiro la dedicación que pones en cada avance, felicidades sigue así.
Muchas gracias :-)
👍
Excellente Arbeit👌👌🤌🤌👍👍👍🔥🔥
Отлично !
helikopter'in önünü ovel hafif sivri şeklinde yapın rüzgar toparlamasın ayrıca farları çift yerine biraz büyük öne ortaya doğru tek far takın böylece daha gerçekçi görünür kolay gelsin
Good ! 👍
Been flying helos for 20 years, Impresive job. See Arthur Young videos About Bell 47 project. Yours looks to have a few oversized elements in tail rotor.
Bagus mantap kerjanya👍🏻
Selamat bekerja semoga sukses😊
We wanted to see how you fit Rotors
I love your attention to detail, but did you forget to lubricate the bearing under the pully?
Very good my King

Quite shocked that you don't have some kind of cover plate over those bearing locating pins. Surely you need a way to make it impossible for them to come out.
You changed the design here...quite awesome!!!...my question how do you intend to go about the modification of the gearbox breather it's such a pain ..have tried a pipe facing upwards and oil will sip through even 5inch higher than gearbox, blocked that breather and drilled another hole on top of gearbox and still leaks when engine runs, planning to try the new hole plus the normal breather hole all open, if they still leak no idea of what to do next...
Lastly am turning out quite heavy, now at 200kgs, might be 230kgs with all fluids onboard, plus my 80kgs weight, so it's not looking good, want to change the chases tubes, what grade and type did u use? Your weight is quite 🔥
Hi, I'm worried about max allowable torque of that kkfl35 sprag clutch, 175nm.
The 582 will produce a max torque of 75nm at 6000 crankshaft rpm. With a 2.62: 1 gearbox that will increase to 197nm.
Just saying.
Hello... Thanks for your comment, but i think the sprag clutch can handle the torque. Engine torque 75NM x 2.62 (Gearbox ratio) = 196.5NM x 1.37 (Belt pulley ratio) = 269.2NM total on the sprag clutch. I installed a sprag clutch kkfl35 Outside diameter=72mm, Inside diameter=35mm Max rated torque= 350NM. So as i calculated right i have 350NM - 269.2NM= 80.8NM below the rated max torque of the sprag clutch.
ഇതൊന്ന് പറത്തി കാണോ ഇപ്പൊ അടുത്തെങ്ങാനും 😂
When u can fly the helicopter??? One year ago don't finish😬😬
That's similar to the free-wheeling mechanism in a Bell 47-G.
Is it an actual sprag clutch or a ramp and roller? (sprag 'clicks' ramp and roller is silent).
I'm guessing the Rotax motor is between 30BHP and 60 BHP depending on actual capacity and RPM? (with 4 belts I'm guessing some redundancy and 40hp?)
What's max torque and constant power the clutch is designed for?
Roller/ramp type can split the outer housing if too much torque is applied although having a pretty decent thickness of pulley will definitely help keep it together

Please tell me where can I buy the bearing?
Thanks

Hello bro weldone work! I want to buy a lathe machine but I don't know what size is right for me, please what size is your lathe machine? Is it 1 meter lathe machine or table top mini? Please I need your reply.
Hy Joseph. Thanks. The lathe i used is around 1m in length. It depends for what application you will use it. Generally i would say bigger is better. For this helicopter project i would choose a bigger one because i came on the limits with the size of some parts i worked on and the motor is for parts with a higher diameter not strong enough to work efficiently.
@@ultralighthelicopter thank you brother, I will be using it for coaxial helicopter project in Nigeria here, thanks for your help I really appreciate it, you are always the best God bless you 🙏
@@JosephBenson I wish you all the best for your coaxial helicopter project. Greetings to Nigeria
Thanks brother God be with you 🙏
Клинить подшипники? Может я чего не понимаю, но кажется так делать не стоит.
Ha ha 15:25, how long do you think those belts are going to stay lined up so nice?
I changed the belts to longer version because of adding a belt drive clutch tension mechanism.
Torque spec looked to be about 35 Uggah Duggah's to me.

Halo boz mesin helikopter berapa CC kah
My friend would you kindly send be the dimensions of this bearing and also the code number?
Sir all yor job is don one go ? Please replay
I admire your enthusiasm, but I still worry about you. Praise is nice, criticism is what an engineer needs. I hope you question your own work and have a thorough knowledge of what you are doing. The majority of your viewers have a lego level understanding of engineering. Be safe mate.
yes, from design and execution perspective this whole operation is very concerning,
Can you sell ready-made pieces
А если зуб отломится на шестерне в редукторе? Я бы поставил муфту свободного хода между винтом и редуктором. Такой вертолëт уже был czcams.com/video/3jgs22-Igdo/video.htmlfeature=shared
