Default RE: Classic Pattern Plane Image-base

At last, for Rainedave and anyone else who might be interested. After 6 weekends of absolutely disgusting weather this Winter Sunday was one of those calm, clear days that you often read about, but never actually enjoy. The Sicroly has flown, the old $40.00 Webra runs without causing any moments and the model has started the trimming process. It won't take much, a bit expo to tone down the ailerons around neutral as they respond to the slightest stick twitch and a bit of elevator movement reduction as it responds splendidly to the elevator, cg may be a little back from optimum, but the thing is speed stable as it is so I won't be fiddling with that too much. Almost totally neutral with the sort of dynamic stability that makes it stop just where the controls stopped, a real 'arrow'. This one is obviously not for the tentative but will track 'just so' for an accurate pattern pilot. Nearest I can compare it to is my beloved 'Superstar'. I know it looks ugly on the ground but in the air it looks pretty good. Inverted needs the merest whiff of down, rolls need almost no correction, just a wee tab of down as it rolls over on its back. The flaps do have a nose up trim change, maybe the cg again, but so long as I throttle back to just over idle no trim adjustment needs to be made. The thing floats around with the flaps down at what appears to be somewhere way under stall speed, but nothing untoward has yet happened and the landing is accomplished with wee dabs of down elevator to make sure it will actually contact the strip. Real slow nose high landings, of course, almost without pilot intervention. Interesting. I have my usual 1~2 deg washout built in to the wing, this may account for the good slow speed manners. Even so the stall is positive, the spin quick and recovery instant on letting go the sticks, just what is required. All in all, not a bad model, certainly a competitive one once fully sorted.
