just a quick question, is Dubro hinge tape (Blendtherm) nitro proof? If not what do you personally use as hinges on flight control surfaces on 1/2A aircraft? CA mylar hinges perhaps?
I use continuous hinges made by slotting the entire TE/LE on a Dremel router table with a wafer-thin saw blade, then inserting a strip of Coverite or 21st Century fabric covering and wicking CA.
I have not used fabric covering as individual hinges yet, by that I mean as individual hinge strips inserted into cut hinge pockets, but I can't think of a reason not to. The stuff is tough (far stronger than needed to deal with the forces involved), has a glue-friendly coating on each side, and is fuel proof. And it is highly flexible. If the slot is tight inserting the hinge will be like the old phrase "playing pool with a piece of rope".
The hinge tape is not fuel proof. The only tapes I have found that will resist fuel are specialty tapes that use silicone adhesive - if you put them on a virgin surface prior to spraying everything with oil. Afterwards, good luck.
