I guess in hindsight that was a bit presumptuous of me, but it seemed like such a good idea at the time... I'll try to read up more on these things...
One of the things I do find is that I can spend allot of time searching and then not find what you are looking for even though you think the thread you have found will have the relevant information (think Google.) I.e. what is the best angle for the vortex generators - the angles on the wind tunnel test vehicle, the angles the manufacturer recommends or the angles on a Cessna 170 - you see what I mean. I love and appreciate this site all of you have built and it has a wealth of helpful information but sometimes I just have to type in a question and see what people who know have to say. Since the 240, 260 and 280 all are basically standard to each other I thought there would be, in this case, a close to best configuration.
Sorry I ruffled any feathers...
