The vacuum pump is running in my workshop on wing nr. 2 (upper side), so some time to sit behind the computer and look at the decals and logos.

We will be using HB-935 and upwards for our Elfes. The decals are pretty standard: the registration number, a Swiss cross as well as the initials of the pilot/builder. We also decided to add a nice Elfe S3 logo under the canopy. There are various versions in pictures online, see some examples below. I used these to draw our own logo.
