10 Pound Payload Heli?

[kingsflyer]

Does anyone have a suggestion for a Heli that could lift a minimum of 10 pounds of payload and still be realitively easy to fly? I would guess a counter-rotating system would be best for stability and ease of flight. Thanks in advance for your help.

You need a Yamaha RMAX:

These look pretty GOOD. :D I'm amazed that neither one requires a twin rotor system for hover stability. I'll check them both out ASAP. Any other recommendations?

You could also have a look at what this company is using -

I was bought a powered parachute kit from this firm by my son.
The kit was completely supplied by airfoil and was duly constructed by an experienced aeromodeller friend. The machine has NEVER left the ground and despite numerous emails and one despairing phone call from the UK I have had one email back and no further help.

Draw your own conclusions!

This is exactly what I want, but I do'nt want the helicopter to fly around or do fancy loops - just UP take my photographs and then DOWN -2lbs or 1kgm
payload would be sufficient to lift my remote controlled camera system which I am using at present with a kite.
"Normal" helicopters with their torque cancelling rotors are notoriously difficult to fly and the coaxial way seems to be the answer.
Do'nt suggest using a mast or balloon-I looked at these possibilites - this is why I originally went along the powered parachute route with SAD results

hi
a coaxial would be great but there are no production models that are large enough to carry even 1 kilo , there are a few custom or scratch built models and it is posible that someone will market a larger coaxial , but in the meantime the .90 size or gasser helis are about all that is available , you might consider a standard heli equipped with a co-pilot , dana :)

great link! SC :D
thanks :D

century predator gasser condor should give you 10lb payload. it is also affordable for heli this size. there are few gassers that are useful for this much payload. (bergen also make good heli. Vario is another option)

Thanks for your help. You folks are tops!

About the "Coaxial way may be the answer" comment: coaxial, if done right, *might* just buy you a slight amount of stability in a very small, indoor (zero wind) helicopter. But as soon as you go outside and have typical outdoor conditions, it won't help you at all. There is a fundamental challenge with all VTOL aircraft in that you have several degrees of freedom (different ways the aircraft can move) which the pilot must correct for- and he must do it on all axis simultaneously! This is what makes it really challenging. Think of trying to control a hockey puck on ice. Now imagine that in 3 dimensions instead of 2. Then imagine instead of just moving in 3 dimensions, it can also rotate and tilt in 3 ways.
