I've never noticed it, but that doesn't mean it doesn't happen. For most throttle transients, the combination of prop momentum, throttle pump and induction system effects will hide the blade stall transition. Especially true if you have a controllable prop. Have you checked whether the blade profile implies that the whole blade stalls and unstalls at the same time ? It may be gradual. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
