<DIV><FONT face=Arial size=2>I pretty much agree with Karl, Chad, & Eric.
The balsa foam airplane may change trim, depending on the linkage, hard to tell
just what will happen with the composites. Batteries are the biggest concern.
When I lived where it got cold I would test airborne radio systems in the
freezer at 0F. About 25% of the servos simply quit working - everything else
seemed OK. As the most volatile fuel component has a flash point (makes
flammable vapors) of +50F, engine starting is a problem. As Karl mentions,
lighter fluid (couple of drops) helps. My record for cold flight is -6F, but the
best solution I've found is moving south - been in the upper 70's in Houston all
week.</FONT></DIV>

degrees..... I spent extra time warming the YS at idle, but thoughts
were crossing my mind about how bad the cold weather is on our equipment
(nylon components etc....) . I'm sure the guys up North have limits on
cold temps and I'd be interested to hear your concerns or special
cares.</FONT></SPAN></DIV>
