Same here Dean, Michigan winters are very...er...good...for building. I used standard servos everywhere, this is a easy flier. I did only two servos in the wings (the plans call for one in each wing half) and linked the lower to the top using 2-56 rods. Two years of flying (this is my regular flyier) has shown now wear on the servos, everything in that department is nice and tight. Just beware of the rudder hinges, with the skid attachted to the rudder you might pull them out on a hard landing. Jim had some good advice on reenforcing the tail skid, all I did was to pin the CA hinges in using toothpicks and that has worked very well since I pulled them out on my second landing.
