Thermaling in 20F/-7C-Fun Fun
Got to get out and fly the Sirius after a depressing 3 week weather break. Just dream conditions, 20 F, freezing feeder winds, crunchy grass, but strong sun all day. Jammed the nose of the Sirius into the heater vent on the way to the Bucknell sport field to bake the lipo pack until toasty.
Was not too hopeful for the day but saw a Hawk pop some air near the field. Launching with a ski parka and gloves took a bit of adjustment but was getting some good height. When are they going to make heated sticks??? All those spare Lipo tranny pack amp hours should be put to good use.
Third throw and felt some energy, not too bad, a 2 minute with huge sink after. A few more throws toward a shift, and bang, up she goes smartly, feels like a spring thermal! 250 fpm I think, I'm way high and downwind in 2 minutes, which stretched to 6. Not bad for the north pole.
After a long sink cycle, hit some more air over the field hockey pitch, and another strong thermal took me way up across the golf course, going up FAST. Amazing lift for the conditions and low sun angle.
I think this is the coldest temps I have HLG'd in. Got 30 minutes of flights, then with nose frost bitten retired to the comfort of the Eurovan. The Lipo did fine in the cold, used only 99 mah for the session.
I'll have to get out in the cold more often, it felt good, and lesson learned, good air can happen at any temp, though strong sun helps.

I've found the best thermals come in the cold days, flying a Zagi tazz in the winter I get bounced all around especially in the afternoon from thermals and sink. I'm sure some meteorologist or physician could elaborate on how the air turns over more when it's cold for some reason, I wish we always had lift like this, but warmer =]

I made something pretty close to this to keep my hands warm....works AWESOME. I also added a computer fan powered by a 9v battery to keep the window from fogging.....without the fan blowing out a vent hole your radio will get wet after 20 minutes from the moisture of your hands.
For DLG use definetly do some dry runs of throwing the plane and then sticking your hand in the hole.....I lawn darted once when I wasn't thinking, no dammage, but damned embarasing

Just two months ago I convert my RG in to DLG. The new year found it in Naperville IL at 10 AM in 8 degrees F. Amazing for 15 minutes lunches had two thermal strokes .I think next new year to stay in MD, more friendly weather.
