Counterweighting to prevent flutter by
[email protected]
Is there a simple (or complex) guideline for the relationships between
CG, pivot axis and aerodynamic center for a control surface to prevent
flutter?
Is it as simple as keeping the CG at or ahead of the aerodynamic
center, similar to designing for stability of the aircraft itself?

Naive antiservo tab question by
[email protected]
IIUC an antiservo tab works by deflecting a control
surface in one direction so that the control surface
then exerts a torque in the opposite direction.
For example, suppose you have an airplane that tends
to yaw to the right with the rudder and ailerons in
their neutral positions. An antiservo...

Alloys for certified parts? by
[email protected]
I have run across someone who insists that
6061 T6 is not "aircraft grade aluminum".
He claims that there are no certified parts made
from 6061. I find that hard to believe. Aren't there
certified aircraft with welded aluminum frames?

Bending graphlite rod by
[email protected]
The data on the Marske website about the graphlite (TM) rod they use
indicates
a glass transition temperature of 212F. So I tried heating some with a
heat gun
to see if I could put a permanent bend in it. No luck.
I think maybe it uses a phenolic resin which is thermosetting, rather
than...

Corrosion at Aluminum/Steel Junction by
Front Office
I need to build a dozen outdoor canopies for an office building.
I want to use structural aluminum channel, bolted with steel bolts.
Where might expect corrosion to arise over the years, and would
it be mainly in the aluminum or in the steel bolts?

Sport Pilot inconsistency by

I am unclear on two Sport Pilot issues: First, a new pilot may qualify

Flying wires by

Just out of curiosity, I notice that all of the Pitts aircraft have
flying and landing wires attached on only the main spars, and the Acro
Sport aircraft have them attached on both the main and rear spars.
From what I have seen, the wings on both aircraft aren't made much
differently, and I...
