Prezados bom dia! Novamente mais um show de engenharia. Vocês não se cansam de impressionar. Estou estupefacto com a beleza do trabalho que é lindo. Parabéns mais uma vez pelo nível de excelência e de fazer jus aos engenheiros. Obrigado por nos prestigiar com tamanha Técnica.

[@Alex-Pilot]

Редуктор без масляной ванны долго не проработает, смазку раскидает по краям от центробежной силы. Eng: The gearbox without an oil bath will not work for a long time, the lubricant will scatter around the edges from the centrifugal force.

Думаешь так и оставит ? Помню в дедовской ручной дрели было так же :)

[@mrboby5]

no encuentro la hora de que termines el proyecto y ver si vuela, he visto todos y cada uno de tus videos y me entusiasma ver volar el helicóptero. saludos y buen video.

[@bruceyoung1343]

Sure is nice when you have the right tools and the knowledge to use them.

[@newazkhan305]

❤️ your Work.

[@aviator267]

Amazing work. Did you manufacture the gear and pinion?

Que moral, gostei isso é trabalho de um verdadeiro profissional ta de parabéns..

Здравствуйте! Спасибо вам за прекрасное видео. Расскажите нам пожалуйста о стоимости всех работ. И сколько стоит двигатель?

[@diy2314]

Hello well done

[@michaelm.7913]

What an inspiration, much respect. What's the spindle and center size of the lathe you use? I recently bought a 7 x 14 and wondering if i can do a similar build, later down the line.

Good jod bud. Very proud of you👍🏼👍🏼👍🏼! Now i have a question for you. . . . ."What is the gear ratio on this gear box you just made"???🤔🤔🤔

[@chippyjohn1]

He does show the gears, count the teeth, 30 and 15. A bad idea for gears. A hunting ratio should always be used.

[@truckerray7533]

@@chippyjohn1 Yeah, I wasn't necessarily talking about counting the teeth on each gear. . . .but more so on how many turns per revolution from the bigger gear to the smaller gear

[@chippyjohn1]

@@truckerray7533 15:30, 2:1. 2 turns of small gear = one turn of large output gear.

[@truckerray7533]

@@chippyjohn1 Thankya for that! i appreciate it! That is not a huge gear ratio espect at all! Theres still the tail rotor gearbox to figure in as well. Most all conventional helicopters will have anywhere from a 1: 5 to 1: 6 1/2 gear ratio aspect

[@chippyjohn1]

@@truckerray7533 Ratio is actually 2:1, apologies. His engine operates at 6000-6500, so output shaft is operating at about 3-3250 rpm.

[@ruatahanghal5121]

Your works are excellents next level !! Which engine are You using how many cc or bhp power input can you tell me in details please..

[@billyjasinski1265]

so glad you made another video. I thought you would fill it with oil, but then you sealed it up. I was surprised you put the gaskets on it. Are you going to take off the "not final bolts" and fill it with oil? if not, what are the gaskets for? some of the music was bad though🙂

[@muhammadardiyanto6289]

is this dry gearing or lubricated? thanks

[@remalnik]

I lake look your video👍💙💛Я с Украины!

[@bruceyoung1343]

No locktight on those bolts ?

[@ultralighthelicopter]

These are not the final bolts i will upgrade them.

[@joshc7091]

@@ultralighthelicopter Some don’t understand in building a flying machine you do it twice. First round with cheap hardware and when it’s done take it apart and go back together with the good stuff now that we know what we need and exact length

[@TuberEver]

👌👌

[@drush525]

Nice, why didn't you add a magnetic drain and fill plug so it could be serviced as well as splash baffling?

[@JosephBenson]

Bro good job really appreciate 🙏 I want to know the main machine you are using, is lathe machine, CNC machine and blench driller the main machine you use?

[@ultralighthelicopter]

Thank you. Yes i am mainly using the lathe and cnc machine for the parts...

[@JosephBenson]

@@ultralighthelicopter God bless you, keep growing and you will see the end of your project successfully in Jesus name amen.

[@chippyjohn1]

I know you state this is not educational. Just want to point out the importance of a hunting gear ratio. It looks like 30:15 or 2:1 ratio. Ideally it should be 31:15 for a ratio of 2.066.

[@ultralighthelicopter]

@First Last Check out my upcoming videos to solve this...

[@chippyjohn1]

@@ultralighthelicopter I'm watching. Working on my own helicopter, very different though. Just worry about you.

Hello sir when will you fly it we are waiting and exciting

[@Mehmet__]

sir when is the final ? we look forward to it Thanks...

[@alexpalios2570]

Hello these gears are not appropriate for this porpoise. You must use spiral bevel gear in order to have smooth transition without vibrations. I can share some photos of my gearbox but I don't know how to send with KZbin.

[@erwe1054]

Почему не показал настройку пятна контакта ? И еще вызывает сомнение базирование крышки с подшипником прямо на мягкую прокладку. Надо было сделать упорный поясок и рассчитать так, чтобы прокладка обжалась на пару десятых мм, потом крышка жестко уперлась в поясок. Иначе от степени обжатия прокладки будет зависеть осевое смещение зубчатого колеса и непредсказуемое пятно контакта.
