Hi All
Any body know what a "Frieze type " aileron looks like and what are the Por/cons in using one.

Here's one way to get the Frise aileron action.
It's accomplished by putting the hinge axis off-center from the surface center.
The nose of the surface protrudes below the lower surface of the wing when the surface moves up, adding drag to that side.
There must be room ahead of the hinge point to permit both up and down clearance for the surface.
The hinge can be on the bottom surface also.. the inflight shot is a Frise aileron in a left turn..
They look different but I don't find them any better than normal ailerons.

Thanks Tall Paul!

Will try it out since the real aircraft had it I will use in on my project.

The idea of the Frieze design was to have a lip come down on the up traveling aileron to add drag to the wing on the inside of the turn. This was intended to counteract the adverse yaw effect from using the ailerons and reduce the amount of rudder the pilot needed to initiate a turn. I think a lot of this was intended to reduce the workload on the pilot's muscles. Of course we don't have that problem wiht our models but if done properley it may make the turns look a trifle more coordinated.

Good luck with your project Yak.... whatever it is.

Thanks for the information BMathews,

I am building a Lavochkin - La-5FN and the 3D scale drawing of the full size aircart has these ailerons. So I am thinking of including them in the models design. However it may need a bit more work to change existing desighn that I have. (All is scratch build design included).

Will post more information under Warbirds.
