Ouch! Control flutter and reduced sick force per G at high g

Well, this is homebuilders heaven - so I suppose we could use a
reminder that balancing control surfaces, specially tail feathers,
can help stop the onset of flutter, that loose control wires
and rods can encourage.....

How do you balance ailerons that aren't hinged?



Well they are hinged just that the hinge is an extension of the upper
skin of the aileron. Interesting point though. It seems that most if not
all of the accident aircraft did use a more traditional piano hinge?
