I just finished and now have about 15 flights on my Giant Aeromaster. I deviated a bit from the kit plans as I made the elevator a one piece unit and am using pull-pull on both elevator and rudder. I also over powered it. I have a Quadra 72cc swinging a 20-10 prop. It weighs 20.5 pounds dry and flys like a trainer. I'm using Colman camp stove fuel as the gasoline here in Florida contains 10% alcohol and that was fouling up my Walbro Carbs. After two rebuilds of the carb I switched fuels and have had no trouble since. My reason for the Giant Aeromaster was that I have had seven of the old Aeromasters and liked them so well I decided to try the big one.
