Whats the worst flying plane you ever had your hands on??
I bought a built Andrews Minimaster a long time ago and it was a nightmare. It rocked back and forth in the air and was a snapper on landing. A friend told me to reflex the ailerons (raise them about four turns on the clevises). I did that and it was a whole new airplane. Had an OS .25 in the nose and was a beautiful flier. Sold it and the buyer decided to put a larger engine in it. Bye-bye Minimaster.
