Have you tried one of the Seagull Models ARFs? 6 hours is very generous to try and assemble it! Between the crappy instructions (install the wheel pants and wheels by following the pictures [:@]), and other things like that I think it probably took 8 hours, and I was in a hurry! If that is what you get with "inexpensive" ARFs, I will pay more in the future for a good manual. Engine rotated 45 degrees counter clockwise. I think it took over an hour to locate the proper places to make the cuts in the cow (misspelled intentionally, that is what the manual calls a cowl) for the cyliner head and needle valve extension.
