15mm hinge tape, where to get?

Ich mach mal in Englisch weiter, evtl. interessiert Stein meine Frage auch:
@czfridolin
Can you explain your Orastick method? I tried it myself a couple of years ago. My problem was that the ailerons lost their middle position after a while. The ailerons moved up and were out of the alignment with the profile. I thought that the servos pushed the ailerons up.
Maybe you know a little hint to solve this problem.
 
@Schaafschuetze
I use it exactly in the same way as i would use Tesa tape:
Fold the aileron fully up cover the bottom side with a strip of Orastick then fold it back to neutral position and cover the top side with a strip.
works fine for me..
