I just purchased the Groovy 90 3a pattern plane.

I will never compete but I like flying my Groovy 50 3a with a Saito 82 a lot.

After purchasing the Groovy I see where they designed it for the YS 91 supercharged motor.

I am not a YS fan. I am a Saito or OS kind of guy. My idea of engine maintence is wipeing off the plane when done.

What other options are out there? I like 2 strokes. The claimed flying weight is 8.5 pounds.

I'd even buy used if I could trust the seller.
