The Goldberg Anniversary Cub is the way to go....
I had mine for 15 years....and just sold it....it's built
like a tank....I had a Magnum .91 4-stroke in mine, and
I built it "clipped wing''....it's a winner.
I had the other build-up one too.....The Sig (I think).
The wing folded on the first flight.
