Very good guesstimates can be made given the right book, the right info, and the right aero engineer. ;-) > 4.

I sent some info to Dave Luff a little while ago for the B-17 Wright Cyclone. Eventually he'll get something for us, I am sure. :-) Jon _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
