Next time I will make an effort to ..primarily rpm, then air loads, tip speeds approach Mach 1. Also, noise frequency plays in, for airport survival, you want big slow turning props. Not 11" toothpicks turning 18000 rpm. ..firing 1/2" thru 40mm ammo at drones with 13" picks turning around 8-10 krpm, returns nice snaps from shock waves meeting each other. Sounds pretty much like bullets hitting a target at a shooting range, sitting in the target pit. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;-) ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
