RE: Trying Monokote for the first time...
I've covered a few with each, and have really gravitated towards Ultracoat. I find my covering results to be better with it, and after it's been reshrunk once or twice, it seems to stay tight better than my monokote planes.
I love the sound of raindrops pinging on a tight wing cover job as we pack up while the showers roll in.... Except that it means an end to the day's flying!
