[WWI] Maurice Farman Aileron Control Question

[Knut Erik Hagen]

Hei,

Early Farman aircraft can be seen on the ground with ailerons on both sides
hanging down.
When in flight would it be possible for the pilot to depress one aileron to
lift the wing, but there would be no raising of the other.
I think it was because it made the control runs simpler and they would avoid
loosing any of the precious lift on the opposite wing.

The aircraft on display here in Oslo is a Farman M.F.7 Longhorn.
It is not assembled/rigged 100% right, just like the Bleriot XI next to it
with its horizontal tail installed upside down.

Looking at the M.F.7 on display in MAE does it seem to have one aileron
up while the other is down, the downwards movement appears to be twice 
as much or more than the upwards.  
This matches photos I have of M.F.11 aircraft in flight.
So I would rig the model with one aileron down and the other just a touch up. 


  Eders
Knut Erik
