Smallest possible helicopter?

Hi, I was wondering what the smallest possible electric helicopter size
would be,

I would really like to make a basic 2ch electric one using the electronics
from those minature rc cars, u know, the Tomy bit charg or the other 1:43
scale clones.

Is this possible??

I doubt it myself, but what do you all think? I woul like to go smaller than
the homemade pixel helicopter that someone made.

I want to use it indoors u c !

Thanks

Scott

All cats are animals, but not all animals are cats.

I would think the smallest electric helicopter possible would be one of
those nano-bot things the Japs can produce. probably a few microns across
the rotors.

The smallest useable, r/c indoor helicopter though would likely use
technology "outside the box".

Why not use five or seven large feathers (or shaped Depron) as the rotors,
make them fixed pitch, and use two contrarotating heads to eliminate the
need for a tail rotor use a small motor driven from a large capacitor as
the source. Use the tiny r/c system used for paper planes as seen in RCMW
recently for control.

Or you could use depron and make a two rotored gyrocopter., driven rotors,
no tail needed.

I started to make an indoor gyroplane out of pikostik parts and depron
blades, but events over took me and it languishes on a shelf now.

Anything's possible, but flying a heli which requires a minimum of FOUR
channels with a 2 channel radio isn't likely to be an EASY possibility.

Re: Smallest possible helicopter?

There is NO way to do it with 2 channels, mate. You can do an airplane with
2 channels, because it is always flying forward and therefore, you can get
by with controlling yaw (rudder) and throttle (up/ dn). The third axis,
forward/bak is set permanently to forward by the prop.

Hovering craft need constant correction in 4 axis and therefore need at
least 4 ch.
1 fr/bak
2 left/right
3 up/dn
4 spin (rudder yaw)

Re: Smallest possible helicopter?

looks like i may have to try the 4ch approach then.

That bloke who made the pixel heli is inspiring!

48g is the weight of the pixel 2000!!!

Thanks
