Thanks - that was the same direction that I was thinking about but didn't want to 'lead' the replies. Since the 'lobster tail' hydroplane uses a single canard between the two sponsons instead of two canards on each side of a fuselage, do you have any thoughts on whether the entire wing should be adjustable by the heading hold gyro, the wing should be split in the center and controlled by two gyros (maintain roll also) or if smaller right and left 'elevators' on the rear of a single canard wing makes since.

I realize that this is mainly guess work without some trial work but it still might help in the initial direction to take and reduce the number of versions to try! I am planning on using a homemade wind tunnel to do the initial experimenting with to reduce the occurrences of catastrophic 'flipping' incidents.

Thanks again for any educated guesses.
