How to start 45 year old Russian helicopter ? - 1969
How to start 45 year old Russian helicopter - Kamov is a Russian rotorcraft
manufacturing company, founded by Nikolai Il'yich Kamov, who started
building his first rotary-winged aircraft in 1929, together with N. K.
Skrzhinskii. Up to the 1940s, they created many autogyros, including the
TsAGI A-7-3, the only armed autogyro to see (limited) combat action.

Are Cheap Toy Motors any good for helicopters?
I am trying to answer two similar questions here.
thecrazychef1 asked "Could you make a helicopter powered by a small
electric toothbrush motor, like an Oral B?"
David Peeters asked "Hey could you make a flying machine like an helicopter
with an ordinary toy motor and ordinary batteries (like AA) with the
batteries off-board wired to the machine as it would obviously be to heavy
to carry them "
The results of my tests are not promising but may be improved with better
Honest answer, you are wasting your time. That is what I am showing in this
Try taking a close look at a proper toy helicopter and check how it works.
It will probably have a gearing system so the small motor can turn a large
prop and it will be powered by a very small LiPo battery.
You can buy the component parts for small helicopters on eBay so you could
do that as a short cut or you could just buy a small helicopter.
I understand it would feel good to make one from scratch but you would be
better off getting a cheap one and seeing how it all works before trying to
do it the hard way.
There is a lot more to making a helicopter than just sticking a prop on a
motor and pointing it at the sky. A single rotor helicopter will just spin
out of control. You either need to add a tail rotor to counteract the spin
or have twin rotors spinning in opposite directions to balance out the
torque. Then you need to trim it to fly in the desired direction. Without
radio control you will really struggle. Most mid range priced helicopters
have automatic stabilisation and all you do is point it in the direction
you want it to go.
Reading the comments here about the fact the thrust from the propeller is
pushing down on the scales so the reading is incorrect makes me laugh.
Quite possibly but the point is the motor is not rising off the scales
until I overpower the little one with 9 volts compared to the 1.5 volts it
normally gets in the toothbrush. When I do that you can see it flips the
arm up OK. I am not really trying to measure the thrust here, I am trying
to lift the motor under its own power. All the motors I used here are
normally powered by a single 1.5 volt battery. I have another video where
I measure the thrust. I find it interesting how many replies I have here
that have focussed on the detail and not the obvious issue, can the motor
lift it's own weight? http://youtu.be/9PfErFnXyt0
To address the comments on the thrust pushing down on the scales I have
uploaded another video to show the effect http://youtu.be/4cd-20N72vc

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them
too. If anybody else likes them, that is a bonus. I like to keep my work as
simple and basic as possible so that it can be copied easily and improved
by anybody who wants to try themselves. I recycle or repurpose items rather
than buy new and when I do buy I like to keep it cheap.
