Control surface hinges

(1/3) > >>

BRIAN COOMBS:
I am just finishing off a new set of Carbon wings for my Whisper and I am looking into the best way to hinge the flaps and ailerons. As far as I can see there are 4 types of hinge available to me: -

1 Traditional plastic hinge with hinge pin
2 Mylar strip Hinge
3 Hinge tape
4 Silicone hinge

1 I have looked into the traditional hinge option, and this leaves an air gap between the control surface and the wing, allowing high pressure air to migrate from one side of the wing to the other.

2 I have also experimented with Mylar hinges and they have the same problem as the traditional hinge, but also allow the control surface to move up and down a little at the fixed end.

So I am left with either a silicone hinge or hinge tape, which do I go for? I have no experience of either, I quite like the Idea of the silicone hinge, but I am a bit concerned about its strength? Can anybody help?

The silicone hinge explained, for you guys who have not seen this method before.

Hi Brian,

I'll go for the Silicone hinges
Go for it, really easy to apply, and really strong.

After that, you can use tape, the best one is a chirurgical one name " BLENDERM", nerver saw it in Ireland, but I can have some.
