Hi Guys,
Like Catfish, I'll let one of the texture guru's who looked after the German stuff answer WF2.
Catfish, I would say the aircraft is a large scale remote controlled job, possibly 1/8th scale or maybe even 1/4 scale. as for exact type, I dont know.
the ailerons, I am thinking individual servos for the aileron control and that possibly the power is off allowing them to both relax and the weight of the aileron is bringing them both into the down position.
but having said that I have seen some actual pictures of WWI types where the ailerons are both in a slightly downward position (nowhere as extreme as above though)
the following is taken from Air Minisitry, air publication 1107, 1931.
A Manual of
Rigging For Aircraft
Ailerons setting of.
284. In order to allow for stretch of cables when under load, ailerons are sometimes given an initial droop, that is, the trailing edge of the aileron is set a little lower than the corresponding trailing edge of the plane. The amount of setting generally varies between 1/2in. and 1-1/2in. measured at the trailing edge.
HTH's
