Really appreciate all the responses on this subject. Been most helpful. Don't flame me for asking this one, but thought I would inquire before trying this. The problem I see with the Robart hinge points is that they are too long and concerned that the ribs won't bite into the wood enough to get a secured fit on the Pitts elevators and ailerons. The size is also pretty wide and the flex point of the hinge appears so large that it will form a huge gap between the two surfaces.

G.P. Makes small hinges points that appear to be the perfect length. My concern is about how strong they are. I could easily mount 5 or maybe 6 of these in each movable surface which combined I would think would provide the strength needed... Yes? No? The reason for asking is because of the length. It appears that I can drill the hole without going through the wood to get a good snug fit and to keep the glue from seeping out the back side. Have any of you used these? Here is a picture and the tech notice.

Tech Notice:The Pivot point hinges are used to connect control surfaces to the airplane,
such as the trailing edge and the leading edge of control surfaces.


FEATURES: The pivot point hinge has four interlocking "fingers" at the joint
instead of the usual three. This ensures an extra strong hip joint.
Locking fingers increase strength and durability.

COMMENTS: Customer will need to purchase the epoxy separately
Hinges look similar to two christmas trees joined at the bottom.

SPECS: Overall length: 1-1/4"
