Hello, allow me to offer my experiences....

The 90 replaced a Behotec J66 in our Élan. This single action made the Élan a completely new airplane. Not only was she lighter she had improved vertical and top speed as well as a super fast spool time made the Élan a very fun aircraft. Starts are simple and easy. Spool time is instant. Installation was easy and straight forward.

We have a lot of time operating this engine do feel free to ask any questions that might help you make your decision.
