RE: CA Hinges on DP Extra
hi Specman
I dont have exp with this exact plane but I have a 25% Giles that im re-doing for the 2nd time
My rudder now has Robarts installed and my other surfaces have the Radio South CS hinges. I feel these to be safe for anything up to 25% or so. If I had the time I would def go with all Robarts on all the surfaces and finish them with Gorilla Snot glue.
just my thoughts, good luck with your project
