"" Just use your head""
If you use more hinges than what is called for you will have no problem at all!!
If, ...on the other hand,.... you use 3 hinges per aileron...the shacking will tear them !!
Also... double up on the outer and inner portions of the control serfaces...this is where the shacking will have the most stress
My bigger planes have easily twice as many hinges as what is called for !!!
