Hans and his little Sukhoi SU26M during spring 2001.
It's a small model, 1.40m (55") with an Irvine 0.53 engine. Both Hans and Donald van Tongeren used to fly with these SU26's. Unfortunately, in the summer of 2001, the SU26 of Donald was caught in midair by a larger plane of another clubmember. The Sukhoi was lost. Then the remaining Sukhoi changed owner, so Donald is now flying this particular plane.
