Last month, I got an email from another builder, Len Schroeder who wanted to sell his engine mount. Len bought his kit last year and he decided to put another engine in it. So we had a deal. It was exactly what I needed, an engine mount for a Rotax 912ULS with airbox. I installed the engine mount today with the help of a friend, André. I also try the engine ring to see if it fits. My engine is suppose to be here next week.
