Default Dual Co Axial Heli

Has anyone tried to use a Dual Co Axial helicopter for AP work?

Tried it once on our CX2. Too much vibration and it had a hard time carrying much weight at all. Not very good results at all.

Well I would guess one of those would have twice the lift of a CX2. You'd still have to contend with the vibrations though.

Could probably be done but it would still need to be a lite camera.

I need to get something that will be able to get out and back in really tight places where a conventional airplane is out of the question. I am looking at a heli but need something that is reasonably easy to fly and can still lift a load topped of by being affordable.

Heck if it was easy it would not be interesting. The up side is that the answer is out there. I am sure I am not the only person with this same problem and someone has solved it.

Amazing. That signature has been there from day one and you are the first one to point it out. That is part of the Red Neck irony of the signature, too bad you didn't have a solution to the problem.

It looks to me that it has the lift to carry around a FlyCamOne without worry. Im hoping you are planning on survey work, because the forward flight limitation of that heli would leave a video pretty boring looking at the same 20ft diameter circle for 10 minutes.

I called one of the importers of the Chinook and was told it would not have a problem lifting 6 oz. That is what my Lumix weighs. You need to tell me about the 20' thing. I had planned on being able to shoot at infinity at about 50' to 100' high.

I have a dozen or so coaxial helicopters, and i find them more stable than single rotor hei's for video. But there are always inherent problems with vibrations... Here's one I did yesterday....go caught by the wind and couldn't fly into it. This is from an Esky Lama "Hunter" helicopter. You'll notice the ground squirming due to a combination of vibration and shutter speed. This was done with an STLabs edvr camera...about the size of a Bic lighter. All of my coaxial helicopters are plenty strong enough to haul up this camera. Check out this link... then look at the other link for more helicopter videos. All done with coaxial helicopters.

Buzz thanks for the info. I will be ordering my heli next week. Looking forward to the experimenting and testing the load limits.

No problem, Scott..... I have two of the Chinook's....one is the "Twister" Chinook, which is very easy to fly... the other is the Walkera Chinook. I've never done video with the Chinooks.. If you want a larger coaxial heli then you should look into the "Big Lama"... it's about 3 times the size of a Lama III and has much larger motors. Your only real enemy is wind. If you Google "STLabs edvr camera, you should come up with a great little camera like I'm using... Camera only weighs .7 oz.

Have fun!

Buzz thanks again. I think I am going to make the Big Lama my next one. From there I will go to a really bigger electric Heli.

The Big Lama is one of my favorites. Stable, flies like a dream, and it's very fast. I have no trouble at all putting mine in a hover at 50 ft.... and if you're trimmed correctly... you can set the transmitter down and watch it hover "hands off". I really like the Esky helicopters. I haven't had one yet that didn't fly perfectly right out of the box. Good luck, and have fun!!
