Just a little more about the day ,the wind there was 6 KM/H it was cold with an overcast sky, a very pleasant day for the task in hand . After the third landing I had gained a reasonable amount of confidence to go around and try again. These were not toucdh and goes as the model stoped each time we put it on the deck. The photo below is of the Big T with the Butterfly and one other Big T in the background. The Big T is a very stable aircraft in the air. Yours Paul T
