George:

Even with the rudder from a B-52 I wouldn't try a single engine flight with the Tiggerkitty. She's a real bear with both turning and burning, when one stops It gets back on the ground. I don't attempt anything but final and touchdown. But it is fully controllable. Main reason for coming down when one quits is lack of power - it wont maintain level flight on one engine.

I have given thought to installing the 0.074 engines, but I have too may other projects under way.

Bill.
