One key bit of info is in your next sentence: > Required 4 clicks down ele > to keep a glide, otherwise she'd pitch up to stall. A tip-stall on launch can come from too much "up," which in turn can come from towhook too far aft, or in this case maybe just from 4 clicks of excess uptrim. There's another factor, too. The wings have to generate lift that's a function of line pull. This in turn is a function of flight speed and lift coefficient (CL). Although you probably felt that it was safer to try a launch with flaps at neutral, in fact it's safer to put the flaps down 10 degrees or so, becuz your wing can deliver a higher CL and hence are less likely to stall right after release. Stretch your hi-start until you have a lotta pull, put the flaps down, and heave it hard. If it starts to act squirrely, tap the nose down. __________________________________________________ Do You Yahoo!? Yahoo!
