When doing your hinges you want to keep the hing gap as small as possible. In order to get full 3D throws sometimes you need to leave a small gap to allow for full deflection.

It is EXTREMELY important for you to seal that gap. If you do not you are opening the door to possible flutter which can destroy a wing and / or plane in a matter of seconds.


To do this I use the same hinge tape you use on foamies. It sticks very well, is almost clear, and it doesnt make any noise like when you use covering like ultracoat. That snaping noise from covering always got to me

I just lay the wing or el. down and tape from the bottom.

1. Extend the surface deflection to full
2. Start with the tape at one end of the surface and stick it to only one surface
3, Slowly move to the end of the wing or el. with the tape trying to make sure it is only sticking to one side
4. Cut the tape to length and fold it in half towards you so that you can get the tape right down in the gap
5. Slowly work the tape across the entire gap making sure you have secured it properly on both surfaces
6. Trim any excess
