Strange Flying Conditions
Dear All,
Here in my part of the World (Mid North Coast of NSW Australia) it is summer with temps in the high 30's Centigrade and RH >90%. Yesterday was a great day at the field with light breeze and strong thermals but very hot!!! I maidened a glider for a member who flys well but suffers from a lack of confidence and was amazed how strong the thermals were. I hadn't noticed much movement earlier in the day when flying my US1000.
After flying the glider I then flew my Morris Hobbies Giant Su-Do-Khoi and whilst flying a harrier with very little throttle ( the model normally slowly settles at this throttle setting was amazed to see it rapidly gain altitude in a thermal, probably about 200' in thirty seconds!!! I spun it down to about 50' and flew very slowly into the light breeze when again I found a thermal and it went up like an elevator. I was able to repeat this process a number of times. Great fun. Something you all might like to try with a lightly loaded model on the "right day". It was certainly a new experience for me.
Best wishes to all for the Christmas Season and New Year,
Colin

RE: Strange Flying Conditions
Colin, we are in the grip of winter here in the US, it has been 3-4C average daytime temp here in my area. I like the way my plane and engine performs in cool dry air, but if I had my way, I would prefer somewhat warmer weather. We get some strong thermal action in the summer, they are easy to find as the birds like them too. I just follow those birds
