[@anthonycapanas2932]

Totally agree. AN & MS hardware is the best when possible. All flight controls should be Secured with castellated nuts using cotter pins. This is where movements of rod ends and rotational movement of bell cranks, levers, etc are attached. You can consult the FAA Accepted practices AC 43-13-1b for further reference. Helicopters are very intriguing and awesome when flown with respect and maintained meticulously. Being a helicopter mechanic for many years, I’ve learned that these machines will give you some kind of warning before hand when something is not right, unusual vibrations are beginning to be felt, or there are strange sounds ie: a spinning bearing going bad with a high pitch whine. Enjoy maintaining and flying your machine. You have a great advantage in knowing your machine inside and out. Working on helicopters are so much cleaner than working on cars. My boss used to tell me, “If you think it’s right, it is wrong.”

[@johnfisher747]

One of the most impressive things I’ve ever seen on KZbin. Guy is a freakin genius, the tolerances were spot on and the tech drawing by hand was, I thought, a forgotten art. Bravo sir, beautiful work.

[@pacoesqual]

Great job! Congratulations! My modest recomendation: use AN bolts & Nuts because they have a ductile failure so you have some prior warning in case something would go wrong. Wirelock everything. In rotor head there are extreme forces so better be on the safe side. Once again, congratulations!

[@ultralighthelicopter]

Paco Beltran thank you very much for your recommendation. I will look upon AN bolts & Nuts for the rotor head i really appreciate it, all the best for you

[@ArionRaine]

@@ultralighthelicopter I was going to say the same thing. You are using the wrong grade hardware. They do not have to be AN. AN just have a cross hole for safety wire (which should be used where necessary), otherwise they are simply grade 8. For hardware that does not require safety wire grade 8 is more affordable.

[@ultralighthelicopter]

@@ArionRaine thanks, i appreciate your information.

[@winged99]

Very impressive over-all. I agree with the previous comments. I would add that a Nyloc fasteners use a nylon collar for it's locking feature. The nylon can degrade due to environmental factors like heat and weather. The fasteners would eventually work loose randomly. A helicopter rotor head is just about as critical as it gets so safety wiring each fastener is a must. Thanks for sharing your journey on this!

[@chrisruf7590]

If any of this is not intended for service disassemble I would weld some joints as it is more vibration resistant

[@nbadhorse]

Excellent video. I really wish there was narration. I would love to hear about the thoughts of the designer/builder. The problems encountered during the manufacturing process etc.

[@corymcdonald3703]

[@airgunningyup]

froom 10kg to about 2 kg , nice work

[@GasketManzrevenge]

Wow. I mean that. I have a project in mind and not all the tooling I'd like to have but with a little ingenuity.. You've displayed that in your project. I do have one question about the thrust bearing assembly. Is there a purpose to only using one hard washer on one side of the bearing? As I understand it the pressure on both sides of that bearing will cause it to 'dig' into the aluminum side that could increase friction and reduce smooth pitch rotation (albeit a small degree) and with forces in play would wear into the aluminum and allow the clamps to move outward which in turn would effect balance. *OR* You've taken into consideration the immediate wear and preemptively accounted for that in the build dimensions as well as the increased friction. I'm confused because I'm used to using hardened washers on both sides to keep the load even across the bearing. Awesome project! Can't wait to see her in the air!

[@rondillard2362]

I don't think I would make a part as critical as that out of aluminum, I would not bet my life on it. Maybe for a RC helicopter.

[@1crazypj]

You need hardened axles (or pivot shafts) to use with the needle bearings. (or hardened bearing race if weight is an issue) If using anything non hardened you would be far better off with bronze bushings as they give much greater bearing surface and support even if they do need greasing. You should turn some tubes for those long bolts or they will wear the plates and could also possibly bend them if someone 'helpful' tightens them too much. Are you weighing and matching rotating components to reduce vibration to a minimum or is it something you do when all the parts are finished?

[@devajitsaikai5284]

Awesome talent ... Can you give me the parts measurements

[@nerdthingy]

Hey! While this is a super cool project you have to see that you're making some mistakes! - How are those bearings going to get greased? - Steel hardware on aluminum going to introduce corrosion - No hole deburring will introduce micro cracks - So many plates and bolts, Its going to chafe real bad! Not hating! Just want you to be safe!! Good luck!!

[@nssherlock4547]

Let us know how the Aluminium bolts worked on yours.Other than the 8.8 Stainless,what other options are there?

[@TricksterJ97]

Nerd thingy has some valid points. I also see some shear loads being carried by the threaded portion of the bolts. This is not a good thing. Once running this helicopter is a metal fatigue experiment in progress, so it needs to be designed with care.

[@mdnoyonnoyon7834]

nice video

[@Raul28153]

Something that concerns. Around 12:20 to 12:40 there are two thrust bearing and two two-part yokes. the thrust bearing is assembles with one hardened bearing face plate on the outside and none on the inside. Shouldn't there be two hardened thrust plates for each such bearing? If that bearing bears against aluminum, the aluminum will deform and cause the bearing interface to fail. Just something I saw. Thouht I'd mention it.

[@ultralighthelicopter]

Hello Raul McCai. I wasn`t aware to put (on each side) a bearing face plate on the inside when i put the rotorhead together. It makes totally sense now. I need to chanche this.... Thank you for mention this... really appreciated...
