I have the co-pilot mounted under the wing under the advice from FMA on a Super Sportster (40). On its maiden flight by our test pilot with Co-pilot off, the plane acted very poorly. We tried all sorts of things to get it to settle down: move CG, reduce throes, you name it. On the last flight I told the pilot to take high and I turned the CP on. The plane immediately inverted and flew beautifully. I turned it off, it went bonkers again so we landed it. I took the computer out and we flew again and it flew like a dream. Thoughts, ideas, comments? All ground checks on the CP were done prior and it was definitely OFF.
