Welcome to this Cap thread Scottrc, I invite you to post any mods or experiences with your cap, all information here will be useful for future Cap builders.
Tom, as you mentioned, taking out the down thrust of the engine will lead to a better looking horizontal line flight, I will leave at 0o and just be careful for nose over on takeoff.
Since the day start to be so long here, I will try to fly 2 or 3 times a week, besides the afternoon is less hot than the plenty day.
Alfred.
