BMatthews;
5/8" +/-. I'm not too good at inches, but I think the total is 1 1/4" on high rates and 3/4" on low rates.

What are turbulators?

Bedford;
I have doubled the elevator throw on high rates and programmed the previous high rates as low rates. If that doesn't help I'll add tail weight until the plane behaves the way I want it to...

The weather is not too bad, and the air is dead calm. Yesterday it was -15C (5F) at the field. The engine runs well, but I am having problems with keeping the monokote in one piece. I can put my finger right through the wing if I want to... Is there a type of covering that works better than monokote in cold weather? My limit is -20C (-4F). Any colder than that, and I'm not flying.
