Paul,
I've had mine flying since August of this year and am loving it!! Being in S. FL, I did it up in Miami Dolphins colors: Teal over white, black/orange pin stripes, orange bottom with a Dolphin's "cheerleader" sitting in the cockpit (actually, a Barbie doll cut to fit)! For power, I chose to use an OS .40FP since it weighed the same as a bearing'd .32 (or equivalent). It is mounted sideways with a Slimline Pitts muffler. There seems to be plenty of power however, it will not climb indefinitely - gravity eventually wins. But there's plenty of reserve for whatever manuever you desire esp. knife edges. The ailerons are controlled via the single servo/bellcrank method which works well. They are also set up with dual rate but tend to fly it mostly on low rate. Rudder is setup with maximum throw - elevator to elevator which I like. All-up dry weight came in at 3.75lbs which is within the limits suggested. I also have an 8oz. tank installed. Elevators also have dual rate but high rate shouldn't be used if at high speed - stall snap occurs when pulled up too hard.
Good luck with yours!! They're alot of fun!!
Ted
