Jochen,

Yes, in the first movie I was having to use about half of the available lateral control to the right throughout the flight, and even more ( ie full right) when landing. Even then it still landed "left wing low" which contributed to the left undercarriage coming off.

On some parts of the first movie you can see that the rotor is level but the fuselage is leaning left ( ie right rotor tilt applied).

I'm not certain of the reasons, but I'm sure that the low rotor rpm had a lot to do with it - I had a number of "roll left at liftoff" incidents when I attempted to do take-offs at that stage of development. Once I changed the blade angles to a more negative value, the rotor rpm almost doubled and the left roll disappeared.
