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.

[@bruceyoung1343]

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

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.

Impressive!

❤️ your Work.

[@aviator267]

Amazing work. Did you manufacture the gear and pinion?

[@kocickyhopkaji8638]

Good job.

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

[@anangprasetya5669]

I don't see any difficulty in working so far, right?

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

Lookin good

[@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 :)

Super excellent brother gare experimental

[@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.

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

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

[@bruceyoung1343]

No locktight on those bolts ?

[@ultralighthelicopter]

These are not the final bolts i will upgrade them.

@@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

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

[@truckerray7533]

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.

[@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.

[@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...

[@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.

hi can i order that part sir

[@regsburg]

would you do a backlash and a crown pinon contact color test and wire locks

[@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.
