Before the engine even had a single minute on it, I had to do a service bulletin from Rotax. The carburator floaters had to be changed, since there were production errors. Easy job if the carburator is freely accessible.Continue Reading... No Comments.
Cowling is now near to completion. Spinner and prop are installed. I am preparing for the first engine start. But I have to move the plane first to be able to install the wings with the tanks.Continue Reading... No Comments.
It was still rather cold in the garage. So we reduced our work in February and March. Nevertheless progress was made on the cowling. Picture below shows all parts of the cowling before riveting.Continue Reading... No Comments.
All cowling doors are finished. So the first phase of the cowling is done. Before doing the final hole drilling I did a test fit of the spinner. It fits quite well. It’s not optimal, it could be 2 mm higher, maybe I can correct this when the rivets and screws are fixed. There is […]Continue Reading... No Comments.

The screws are not the final ones (M5 instead of AN5-21). Unfortunately I do not have the screws. Another expensive […]Continue Reading... No Comments.
The picture shows the unsymmetric construction of the mount to withstand the turning forces of the motor.Continue Reading... No Comments.
Our motor mount was produced by a small company in Germany. We had luck that the Rebel is such a great plane. It is so great that there is a copy available (called “Wild Thing”) which is not unusual in Germany. The motor mount for this copy had exactly the dimensions I needed (how come […]Continue Reading...
