All 3 planes in that picture are all kit built. From right to left they are a Sig Hog Bipe (with an OS 91 Surpass 4-stroke), a Balsa USA Thunderbug (with an OS 46 FX), and on the left is a Great Planes Slow Poke (with an OS 52 Surpass 4-stroke). Unfortunately the Thunderbug died an ugly death earlier this spring. It had a mid-air collision with a helicopter, which was pretty spectacular. The Slow Poke has about 200 flights in just a little over a year. And the Hog Bipe has about 120 flights in about a year too.
