RE: How cold is too cold to fly?
It's too cold to fly if:
Your fuel is frozen solid.
Your fingers stick to the TX sticks.
Your tongue sticks to the TX antenna.
Your eyeballs freeze in the open position.
The clubhouse roof and windsock pole is all that is above the snow.
So on.......
Well, here in deep south Texas anything below 60* is considered a cold snap. Down here we often don't fly in summer because it is too hot!
Safe Flying!
