at our club picnic last weekend (80 degrees and light winds) Jason was flying Allen Brickhaus's Savoy, the original model used for the Dec 1996 article in Model Aviation.
Allen let me fly this model many years ago during the Sig contest. We were looking for a solution on a particular trim problem and we're trying many different ideas but settled on a tank problem. After the new tank, the model was much better. It was a great flying model but the turn was a little soft for me at the time. Later, Allen changed the C.G. which made the turns way better with a crisp and flat exit.
