I use a "S" type hinge for my ailerons. Here is what I do:
first I make 12 small strips of strapping tape

then i over lap 2 strips 1/4" and stick together sticky side to sticky side

then i tape one to the bottom of the wing and one to the top right next to each other, I do this at 3 spots on each aileron


lastly I set the aileron inbetween and press the tape down

and there you have a nice never come loose aileron hinge!

now how do you do your hinges?

I use basically the same technique. I don't put all the tape on the wing and have to fuss with sliding the the aileron in bewteen the "fingers."


Masking tape was used for illustration only!!! Use Bi-Directional Tape or Regular Strapping Tape. I personally use 1.5 inch Bi-Di for the hinges.

Take 2 pieces and put the sticky sides together overlapping a quarter inch. Each hinge requires two of these. 3 hinges per aileron are recommended. One on each tip of the aileron and one in the middle. 3 hinges are good for SSC, Limited B and Scale 2948. I would go with at least 4 for Open B.



Line up the tape so that the overlap will be at the trailing edge. Note one piece on top of wing and the other on top of aileron. Do this for all the hinges on the aileron.



Lay aileron upside down on wing and line up the hinges.



Fold over all of the pieces of tape onto the aileron.



Fold over all of the pieces of tape onto the wing.



With the aileron at a 30 degree angle downward, add a strip of tape over the top of each hinge, making sure you keep the aileron tight to the wing. This helps keep it really tight.

Paul,thanks for posting this very important construction tip.

The over-under method is exactly what I use.

Very strong, very tight and zero flutter...............the aileron will fail before the hinge

Hey guys PLEASE USE THE RCU PHOTO UPLOADER.

Copy large pics into thread makes it sllooooooooow to load. Esp for those on slow connections.

Thx for the heads up however a slap on the hands to those who contribute to this thread from a moderator is better handled via private message.


We do welcome however any constructive exchange of information about the topic.

Paul, thx for starting this thread..... good information.

Strong hinges don't prevent flutter. Maybe stiff ones do, but not slick ones.

Kurt

Flutter can be caused by a number of things......loose servos, slop in linkages, wimpy hinging methods, etc. Eliminating each of these will eliminate flutter.

This method is in fact a strong, flutter proof hinging method.

Flapping in the breeze is different than aerodynamic flutter. True aerodynamic flutter can be combated with "stiff" hinges perhaps, but "strong" hinges won't stop the flutter. They might prevent the control surface from breaking off, but not the flutter.
