<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>

thoughts were crossing my mind about how bad the cold weather is on our

have limits on cold temps and I'd be interested to hear your concerns or
special cares.</FONT></SPAN></DIV>
