Model Hovercraft

I was reminded today that I tried once to develop a remote controlled hovercraft for a magazine. Before starting with the electronics, I needed to design something that would fly at all. I ordered two fast, lightweight motors from the UK for counter rotating propellers. I designed a hard skirt. I was very pleased when the hovercraft flew on water, but even with the counter rotating propellers it gyrated. Also, there was interference between the air-flows of the two propellers. While trying to solve the latter problem, the hovercraft suddenly took a dive and sank. And that was that. OBSERVATION: On the Internet there seem to be few remote controlled hovercraft which really work.
