Hi All,
I've finally managed to solve my problem where the Trimming Knob was
maxed out and still I had to use stick left to keep the heli from
spinning to the right.
In my case, I just twisted the bottom rotor blades (lightly by hand),
to decrease the pitch before every flight.
After a couple of flights, the blades sort of kept the correct shape.
Now I'm a happy rc micro heli pilot!
IM****TANT: Be careful not to twist them too much or they'll break.
The spinning actually happens because either the top or bottom rotor
is spinning faster than the other. When the heli is hovering without
spinning, both rotors should be spinning at the same speed which will
kill all torque effecting the heli.
When you move the stick to turn the heli, what is actually happening,
a change in speed of the top or bottom rotor.
I hope I've explained clearly why the spinning occurs, and also some
knowledge I learnt through research.
Kevin.
