I may still persue the idea in the future. Just to get an idea of how it all might work, I'm thinking of just using a cable and doing it by hand.
This of coarse would just be to test what kind of force is needed to raise the flap.
I'm guessing a considerable amount, since a large plate sized flap moving up into 80 mph air is going to have quite a bit of force.
I want to have it be automated using the electrical signal, since doing it by hand and applying normal brakes would be very cumbersome and dangerous.

Did he specify if this was with metal or plastic gearing? I'm building one out at the moment, looking at the 54kG ones on Amazon with metal gears. Thanks.
