Larry,

Wish I had some more positive commentary. This plane LOOKS like it should fly beautifully, which is usually a good quality. Put it on the water and it moves very easily with plenty of floatation. I'm running a .75 engine on mine which has tons of thrust for the size/weight of the plane. I have taken this bird out on the water a couple of dozen times now and I'm fed up with repairing it. At one point I decided to make it "fly or die", trying every variation of balance, trim, flaps, and technique that I could muster. In the end, it flipped over and started filling with water. I was lucky to retrieve it just barely before sinking. The few times that I've had it off the water, it has either just hopped into the air enexpectedly and then nosed-in, or instantly rotated inverted for a nice crash. And no, I'm not trying to horse it into the air, but the hull design seems to porpoise badly, even on smooth water with neutral, or even down-elevator applied. That is probably why it hops out of the water- when it noses up. Anyway, I'm sick of messing with it and just hoped to maybe save someone else from wasting a few hundred bucks.
