I'm gonna replace the CA hinges on the GP Extra for Robart hinges. I don't know if I should go for 1/8" or 3/16". The Leading edge of the elevator and rudder control surfaces which are the ones who mate with the main surface are 5/16" thick. The leading edge of each aileron is 3/8". I'm concerned both with the thickness of the hinges as with the length.

These hinges come in another format which is 1/2A which seem to be shorter and could be a better fit for the ailerons.

Of you people out there who have used Robart hinges, are there any suggestions?

3/16"



1/8"



1/2A
