@@grayzhu можно сделать очень странный квадрокоптер))) Ка-26-4 так сказать
@@user-nd6lg9nu6z интересная идея
What engine is that? American plane?
M14 engine russian one
And......
well done. do you have videos of tearing it down or faultfinding it?
In fact, I only cleaned the carburetor and did not disassemble it.
LoL
Close 😀, cool engine, from your Kamov?
I have 4 spare engines for my Kamov. This is one of them. LoL
@@grayzhu Four spare engines! 😆What is the plan with the kamov ? Is it flyable ?
@@Ben-Dixey my Kamov still no place to fly. But I keep it always in flyable. I am planning use this engine to make a big helicopter. HaHa. I know it's crazy idea.
@@grayzhu Really? That sounds really exciting, you build amazing stuff and don't get the recognition on CZcams. You could get millions of views with the stuff you are doing. I watched Alan Zhang and his quad copter build, over 2million views and it didn't even fly on that video. The engineering wasn't very good but his video making was excellent. I would like to see you get the recognition you deserve.
@@Ben-Dixey Thank you for saying that. Making a good video takes time and can sometimes be a team effort. My videos are more like documentaries and don't have great explanations. Your videos have a lot of detailed explanations, which I think is great.
帅哥，方便交换个联系方式不？我对S53MV大神的这个RA也很感兴趣，研究了下发现有几个射频管很难买到了，想跟你请教下如何解决的，我看你这是复刻成功了啊

seems a lot happier with the power under control. well done
Hi Grayzhu. What is the design of the helicopter you built at home? This reminds me of the Furia project, but I'm not entirely sure. If you could share the name here I would appreciate it. Thanks
It's designed by myself. Of course I borrowed a lot of mature designs.
Brilliant. You're a natural at this. What is the total time you have had flying a helicopter ?
I haven't counted it carefully. It should be less than two hours. In addition to this R22, there are also my friends' H3 AK1-3 ROTORWAY, which are basically short-term attempts.
@@grayzhu The same as me then not counting the coaxial hovering which was probably another 2hrs. You are better at it than I am that's for sure.
🥰Кошка хочет самца...☝️😬
Where did your get the gears
We’re did you get the tail rotor gear box
I made it by myself.
Fantastic. Where are you located? I would like to contact you. JC
I lived in China
Sounds like you needs a flight instructor. I know a guy!
Happy landings.. and good luck!
еще нужно много поработать :)
Уже настроил, отлично работает на вертолете
Fortissimo👏👏👏
Che buffo 👏👏👏
冷凝器是做什么用的？燃油是否流过其中？
cooling the oil
very nice work, could you explain me more about the regulator, did you do it all yourself? I would be interested in replicating it for my heli...
Yes. I design the governor system by myself. What can I do for you?
Che forte.
It's great pull up your soaks successed.I so admire like that where to start that's matter But Iam never give up.❤❤❤
Sounds like a 2 stroke engine. What model and how much horsepower?
MZ202 engine x2
Mashallah, Mashallah, good luck, may God grant you success, and I hope I will do the same❤❤❤
Thank you.
It's getting better every time
Wow, so impressed with everything. It's flying great. So must be so proud of yourself. Fantastic achievement.
ماشاءالله ماشاءالله بالتوفيق ربي يوفقك وانا انشاءالله أصنع مثلها انشاءالله❤❤❤
Best wishes.
Thank you.

Hover higher please, if you roll over in one of those, you might die
Can you post schematic you've used to build this? Thank you
check the TEZUKURI
Gray Zhu. Put your project up for sale. You'll make a lot of money now that it's tested.
LoL. I am not sure someone will do that...
Beautiful the project. What is the structure of this Helicopter made of. Iron or Aluminum? How thick is the material? 
4130 about 1.3mm thick
It looks like it's flying with forward cyclic to hover . Is it tail heavy? Or balanced for two people?
it's balanced for 2 people. That's normal when one man fly it
Would love to see this fly! Any chance you’re planning on building a two seater coaxial helicopter?
Yes. If I have time I will finish it.
@@grayzhu Can't Wait to see it! Keep up the good work!
where are you located in China?
Hefei, Anhui
