The Polish Olympic Orlik III Model
Plan by John Greenfield
This superb free plan given to the Scale Community is to a scale of 1: 2.08, which gives an incredible wingspan of 7.2 meters. It makes into a beautiful thermal soarer which stays aloft endlessly.
As there is basically no difference between the Orlik III and Orlick II, this plan can be used for both gliders and gives you the opportunity to use various colour schemes.
