Siempre he tenido una duda en los diseños a pistón, en caso de una falla de motor, puede hacer auto rotación? I have always had a doubt in piston designs, in case of an engine failure, can it auto-rotate?
good morning Cameron I have the intention to build a helicopter I will use a subarugust engine to know which plant you used for the construction of the chassis if any modifications were made
wow, It is really coming along , sounds good seems to be running smooth and holding good pressure. excellent work. Do you have an idea of it's over all weight with or with out the rotor and blades?
It's actually a really simple concept, just hard to make it compact and keep the weight and balance correct. The problem with using belts is everything gets big quick.
Nice work my friend, I was also building one right now, possibly it will take off for the first time in camp Joseph Abuja Nigeria, I want to know what software you use to check your engine status on that laptop? Please need reply
Cammeron. when you think of the compactness and relative simplicity of the Hiller Rotorcycle. iguess your machine is the other end of the spectrum in complexity and wieght for a single seater.....Curtis
The gov't is allowing this go around? ;-) Been watching this channel for a while and love it. Glad to see you're back at the tinkerin'. Prettier than a Robinson, too :-D Hey, question for ya, back when I was in the military, I was a jet engine mechanic. We had a problem on a C-130 motor where oil pressure, as you said, would fluctuate (it actually dropped for us). Problem was that the anti-foaming agent in the 55 gallon drum of oil actually separated, and we didn't get much anti-foam action. Next go around, the boys rolled the drum on the ground all the way to the aircraft to mix it up and the problem disappeared! Could that be the reason why you had fluctuations in the oil pressure? Maybe it didn't need modifications?
The authority (CAA) has been informed of this project so if they choose to give me a lobotomy and cut off my hands, they know where I live. On startup the oil level would drop and then rise again as the oil drained back, the level got higher and higher as more air and gasses were introduced into the oil causing foaming. When the oil got up to temperature the foaming would cease. When the engine was revved up the level would drop and not drain back quick enough to keep above the oil pump pickup level, which would introduce air into the system again. The fix was to add another drain tube and use a lighter grade synthetic oil. The oil also flows over a #60 stainless mesh to help separate the gasses. Cheers Cam.
Hi Cameron, what is the gauge on the tube framework by the main rotor shaft near the top? Wondered if you have a pressurised tubular framework for crack detection purposes.
Lovely work, Cameron. A couple of questions if I may? You look to have adapted a cruise control as a Governor. What system did you use? It also looks as though you have a very smart ECU setup. Is it a locally available system. FInally, what part of NZ are you located in? The engineering looks excellent, as does your methodical approach. Keep up the great work!
The governor is just an after market AP60 from Australia. I'm using it to test the machine via remote control at the moment. (saves adding another servo). The ECU is a "Link G4+ atom" made here in Christchurch New Zealand. I needed to be able to tune the start-up settings due to having no flywheel as such. (starts fantastic). I only need to tune the startup and the operating speed (5200rpm). I live in the north Waikato area :-)
This machine is a one off design. It is no different to any other engineering project. Using materials that provide strength and reliability whilst being as light as possible is the hardest challenge. The helicopter was virtually perfected 60+ years ago and I am doing nothing that hasn't been done before. Cheers Cam.
The Subaru is about the same horse power as the V4 Evinrude but twice the weight. The overall weight difference is about 90kg. Might be a struggle to do anything but make noise. :-)
@@CameronCarter1 so has the evinrude proven to be reliable on your heli? Did you build a radiator/heat exchanger to keep it cool using the standard evinrude water pump??
@@bradsamers3014 I love the V4 crossflow two strokes. 140hp @ 46kg. Hard to beat that power to weight, even now. Not very "green" though. I used a car radiator, water pump and belt driven fan, but there is a lot of water gallery modifying to get it cool enough. The water inlets are in the cylinder heads and you need to modify the head gasket slightly to keep a consistent flow around the cylinder. The outlet is through the bottom as normal but the exhaust needs to be isolated from the water flow.
@@CameronCarter1 so this outboard motor has a greater power/weight ratio than an equivalent Rotax aircraft motor? ... even including the custom water cooling system you built??
Wow,looking good Cameron.You are are a clever fella!
Awesome, glad the new build is going well.
Thanks Lisa, I thought a second version would be easier but I'm creating problems quicker than I can solve them. Good fun though. :-)
fantastic!!! espectacular job!!
Hi Cameron, So pleased I “Tripped over you” a couple of months back in the motorhome... best wishes on your next stages...
Cheers Michael, Should have some rotor blades made this summer.

How hard would you say it is to build a helicopter? Because this is a huge inspiration for me

Hi Sheldon, I'm working on an all up weight of 450kg (990lb), Operator and fuel.
Wow
God thats one hell of a complicated machine !

I'm using a LINK ecu. www.linkecu.com/products/wirein-ecus/g4-atom-ii/ (but the older version)

The idea was to get away from any expensive gear transmissions and engines, but the down side is size. (much the same weight though)

I was taught to shake quart turbine oil cans before use and punch them open on the bottom for this reason
Hi.. why there's no new videos anymore? How's the copter build coming up?
Sorry I'm not getting the time I need to play. I have uploaded a short vid from the other day. No real progress as far as testing goes.
Hi Cameron, what is the gauge on the tube framework by the main rotor shaft near the top? Wondered if you have a pressurised tubular framework for crack detection purposes.
Yeah, good spotting. :-)
That whining noise is the electric fuel pump, shows how well the muffler works at idle.... (or maybe a bad fuel pump :-)
Cameron Carter what engine are you using ??
Subaru EJ22
Hello I want to learn with you

Could you share with me the design of this helicopter please ???
Build more copters with in the economical cost
Awesome idea sir how did you manage the returning engine oil from cylinder head?
There are drains welded to the cam covers plus small drains from the inside of the cam shaft seals.
hey do you follow plans or is it your own design? if so what sort of experience do you have that allows you to safely build a helicopter?

which this engin ?how can i manage it?
The video is very good. What is the engine power?
Subaru EJ22, approx 135hp. Cheers.
Great sr i also want a built home made helicopter
Subaru EJ22 about 130hp
how to modify oil sump?
Hi Cam did you try to adapt a modified outboard boat motor prior to using the subaru motor?
Is there a big power/weight ratio between the 2 options??
The Subaru is about the same horse power as the V4 Evinrude but twice the weight. The overall weight difference is about 90kg.
Might be a struggle to do anything but make noise. :-)

What is the rotor blade length and width?
diameter of 6600mm x 180mm chord
it can fly?
No, not yet.
