Muiito legal 😊 acompanhando aqui do Brasil 🇧🇷

I am not en engineer, but someone who has built large RC helicopters. You did not show how the inner root of the blade is made and this is obviously critical to the blade grip holding on the tail rotor. Also, while the overall tail balancing you did is important, this should be the last step. You should first determine the spanwise CG of each blade and make weight adjustments so they are exactly the same on both blades. Once this is done, you can redo the overall balancing while only adding weight at the CG of the lighter blade. Good luck with your build and please be assured that my comments are not a critique of your efforts !

Beautiful! 🤩

[@atef8585]

Good job man 🎉

[@jayatissapeiris6781]

Thank you, sir. I am waiting. you are an excellent engineer.

[@CameronCarter1]

Great work, thanks for sharing. 🙂

[@ultralighthelicopter]

Thanks Cameron.

[@Kdubgrowerz]

Im 100% sorry if I sounded like i was poo pooing this project. I think its so amazing to see people using their brain and their hands to do something. To many of us, myself included sometimes are lazy. To build something from scratch and yes im sure it will fly. Is just mind blowing in a good way.. good for you 1000000% god bless you and i hope and pray for safe flights

[@bruceyoung1343]

😀👍CONGRATULATIONS. SO HAPPY

Tay nghề hoàn hảo❤

[@Ben-Dixey]

looking really good. 👍👍

[@ultralighthelicopter]

Thanks Ben

Nice job

[@marksaxon6577]

Nice 👍

[@jeanpierrebellanger1599]

Bon travail

[@moharoa9676]

Nice!

[@vmened]

Great work! Do you have a plan to cutoff extra length from bolts?

[@Junior_Mech]

Very good man. Are you a mechanical engennier?

[@AJAYdev-pi2qs]

Good Balance

[@jangidelectricalengineerin5754]

Nice

[@pierreboschung9582]

Beau travail. Puis je venir le voir en vrai ?

[@Kdubgrowerz]

Sorry for the trolling. But I wanted to say again. You have my woop woop on this project. I really think you are extremely smart, to be able to be a aviation expert, mechanic, engineer, fabricator, and a content creator. Im sure theres more. But You not only had a dream, you are actually making it real, Im truely in awe. Im sure I sounded like a know it all yesterday. I wanted to say thats definitely not the case, I only know the little i know and thats not alot, if u ask my wife Im wrong all the time. YOU GO BUDDY. I think im just a little jealous is why i was so hard on u about ur tail blades.. ohhhh the wife had idea for you.. radio control stuff is getting literally half scale and larger, maybe some of those parts might help and be super cheap.. again im trualy amazed and in awe.. god bless you man. God bless.

Good job on thr tail rotor build & tests!👍🏻👍🏻👍🏻 What is the gear ratio between the tail rotor & main rotor blade. . . . .How many rotations of the tail rotor blades to One full rotation of the main rotor blades????

[@ultralighthelicopter]

Thanks. When the Main Rotor makes one rotation, the Tail blades make about 4.1 rotations.

[@truckerray7533]

You're welcome & thankya sir for the reply back! I'm always fascinated by the gearing between main & tail rotors!

[@Kolarmodelar]

Hmmm 2kg just for tail rotors. What is the estimate weight of full helicopter?

[@LE-6920]

What for you made all blades so heavy?

[@MsOsick]

Потрясающе!! Нужно было попробовать повернуть педали - разворачивающий эффект будет?

[@GBSUsinages]

Hi, good job there ! Just one thing... The blades diameter looks like not big enough, this combined with the fact that the blade is straight and not curved, you have then a huge possibility off facing LTE...

[@QuadriAnas-gd9fk]

Which type of engine do you use

[@ServingMyJesus]

Was this all done during the F1 off season back in 2021/22?

[@ultralighthelicopter]

The majority was done in this period.

[@giuseppepapis5172]

Hi, what thickness of aluminum sheet did you use, and what tubes did you insert inside, thanks

[@ultralighthelicopter]

I used 0.5mm stainless steel sheet for the skin. Inside the blades are steel rods on the leading edge of the blades (where the bolts go through) and aluminum tubes towards the trailing edge. All bonded together with commercial grade adhesive.

[@user-ul5nl7or8p]

Good/🎉❤

[@marc_frank]

i really don't understand how the blades can be made so simply. isn't a precise aerodynamic shape very important? both main and tail rotor are essentially just symmetrical airfoils. wouldn't some specific design improve performance a lot?

[@Kdubgrowerz]

Coming from a guy that worked for evergreen aviation restoring all the aircraft in the evergreen museum. So main rotor blades need to have real engineering and some very specific things done to have a blade root, to tip correct. There are normally multiple parts and different materials. A tail rotor can literally be paddles from a row boat. The tail rotor is basically there to counter act to rotational force of the main rotor. Tail authority is how well the blade is engineered, built and the size, pitch and a few other things. Im sure at one point this person will get this CRAFT to fly. But does anyone remember how deadly the old mini 500e 1 seater. Home builds are inherently deadly. But that being said, since its obvious this person will at some point be above the ground with this... For god sake please can you bond a solid pieces of carbon fiber or aluminum in the root of the tail blades. The amount of mass compared to the outward force is above the tearing force that sheet of aluminum can handle. I BET MONEY AT SOME POINT. That blade will pull it self off of the grips. Other then 2 thin sheets of aluminum, since the 2 bolts which are horizontal and not vertical to the blade. Another thing time has shown is a bad idea.. put the bolts vertical to eh other.

[@marc_frank]

@@Kdubgrowerz thanks :) i think he has steel or aluminium tubes down the length of the blades

[@JushuaAbraham-sj2xl]

I think that the majority of helicopter rotor's blades are of symmetric profile derived from the famous NACA 0012 and surely there is raison behind this wide spread choice (ex: simplicity of construction, better performance in autorotation......)

[@Kdubgrowerz]

Sick man.. ok. Like I said I could be wrong, yep i totally missed that..

[@Kdubgrowerz]

@JushuaAbraham-sj2xl buddy. Auto rotation is what happens when the engine goes down. Also the tail blades are barely even needed, you must put the heli into forward flight, so the forward flight and the engine not torquing the main blades, you almost need zero tail input during AR. But u do need a diaper ur first time.

[@hartoyotoyo6115]

when your helicopter test fly

[@mastergambiarra]

Acho que você exagera demais em excesso de peças, poderia simplificar, por que aeronaves tem que evitar muitos detalhes, pra reduzir excesso de peso 👍

[@ATF.California]

And here I sat thinking I’m a genius making a game for the App Store while this guy builds a helicopter 🚁 in his garage 😅 respect 🫡 tho it’s coming out beautiful

[@arnemartt]

Nice
