Flying the OneSheet Rollason Beta foamie rc plane off the snow behind my place. Temp was around 14F, but the sun was out, and winds were negligible. I spent nearly an hour out flying and videoing the planes. This plane is one of my heaviest and fastest planes, but in the cold, dense air, she will slow down well, and float some. I spent most of the time just practicing flying close to the ground (after I did this video). The skis are made from Model Plane Foam (as is the plane itself) and tongue depressors - cheap but effective!
