    We are still a few weeks out on being able to fly that aircraft. It is an S2 that is getting the high compression pistons, flow balance, and roller cam :-) Also, we are replacing the instrument panel with a new Executive Glass panel. It will be the only Sport Cub S2 with that panel. Several have the previous version of the glass panel but none that I know of have the GDU375 in place of the 496 GPS.

    The work is being done by Aerosport Power in Kamloops, BC. The same folks who assemble our CC340s for us. I believe they are supplying the parts.

    Compression ratio on a stock O-200 is 7.1:1. The compression is increased by putting a set of (modified) C-90 pistons in. I'm not sure what the final compression ratio will be but its a significant difference.

    9.0:1 for the compression ratio on the "performance package". The owner Pete is referring to is having additional work done.
