Now that Larry has revealed my master plan, I guess that I have to finish the 4 leaf clover next time!
Actually, this plane is quite docile in level flight and the rounds, but will turn a pretty tight corner when needed. With one engine out, it does behave well enough to safely bail out of a maneuver if an engine quits in flight. On just the outboard motor, it will predictably want to yaw inwards, but if you pay attention and lead it a bit, it's manageable, even with a bit of wind.
Overall I'm very pleased with the performance. This is my first attempt at a twin, but I must be a bit crazy to try keeping 2 .049s running at once.
John, thanks much for the drawings.
