Tuomas,

The Booster 90 changed everything about how the Elan flew. Removing the J66 and installing the B90 was a simple deal. We picked up thrust and perfromance and lost weight at the same time. The ultra quick spool times made the Elan really a fun plane to fly. My son was able to do some great short approaches knowing that engine would spool instantly if he had to punch out.

If I was building a Elan today it would have a Booster 90 installed.
