Right..they look O.K. but are very brittle. I used them and lost the plane.
There is just enough meat to take a Robart hinge point and used them for the rudder.
I went with the stock on everything else and paid the price.

HINGE?CONTROL ARM!!!
It will fail and no control=crash
An easier way and safer way would be to use 6-32 bolts and
pieces like torque rod clevis attachments.
Not as pretty but safer
