Chris,
Chattanooga is within my driving range. In fact, SPA has a yearly contest there at one of the Chattanooga clubs.

The original Simla prototype featured in the article hasn't flown since 2012, and I'd like to fly it again from a good field, (mine is a bit rough for this plane). Let me know when you'd like to get together and we can invite everyone with a Simla for a get-together.

I have an OS .90 2-stroke with a three blade prop on mine. Performance is adequate but not spectacular. The plane looks like an airliner when it comes in to land.
