My Aquastar flies great. I try to fly only in less than 5 mph winds but have had it out in 10 mph winds before. She gets to be a bit harder to handle in the stronger winds.
Be sure also to seal the wing saddle and windshield. I used silicon chaulk and waxpaper to form a watertight seal on the saddle. It was flown off water before I did this and I wound up with a bit a water in it. Dried it out and sealed it and haven't had any problems since.
