40-50 degrees! Dang you are one lucky guy! I took my planes out last Saturday, and it was 22 degrees. Unfortunately I was having a problem with my rx, and I didn't fly[

] It was really cool tho, the entire taxi way and pit area was covered by a thin sheet of ice. I really wished I had my trainer so I could do dounuts

The forecast for this weed is a high of 20, and I am planing on flying. Don't worry about the engine, but you need to be careful with the covering on your model because it gets brittle , and you need to be sure to check your batteries after every flight.
Have fun!
