I bought one of these about 8 years ago. I put it on floats with a 40 size engine. Never was able to get it off the water. I am about to try a 61 on it and see if that helps any. Built mine with the flaps and was hoping in would be a good flyer. Let me know how yours does with the 46. I may pull the floats and try it on land. In case your wondering the aircore floats kind of suck in my opinion.
