Temperatures acceptable for equipment while flying.....?

[Del Rykert]

I call it smart. Much easier to get caught up in whirling meat cleaver with heavy bulky clothing and keepings ones balance, let alone not having good feeling in extremities to maintain safety. Everyone is different and has different tolerances to heat and cold. Ask those that have fainted? Is much easier to happen next time after heat stroke. As I stated...  I will stick with calling it smart.

  Man, I'm disappointed, I thought all pattern fliers were tough, disciplined and skilled. I guess two out of three ain't bad!

      So how do you guys ice fish down there?


    I was born in Rochester, NY and have seen all the ice I care to see, unless it's with some single malt Scotch.

      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.

      Chris,
       
      Extreme cold and ultra violet rays will make most plastics more brittle.
      You will not get as much power out of your batteries as would in warmer
      weather.
      In the years when we were running the .60 size engines we would use
      Lighter Fluid to get the engines started.
      Now I just don't go out any more in the cold weather. It does not get as cold
      around here (Toronto.Ontario) as it does out west. They were having -35 Cº
      with a wind chill  to - 45 Cº.  Brrrrrrrrrrrrrrr.
      You wont stay outside longer than you have too at these temps.

      Hi,
       
      Hey, I was out flying on Christmas Eve in OK and it was about 22 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.
       
      I'm running a balsa/foam airplane, YS140 Sport (30% CP Heli fuel), and a JR PCM 10X with Digitals and Nimh batteries.
       
      Thanks for your feedback....!
