I'm back, it took some cypherin' but here goes. On the offset of the vertical stab, again I find that the dimensions appear to be inversely proportioned to the square of the distance. Hypothetically, for a lack of parametrical dimensions of the cyclone in question, lets say the length of the vertical stab and the recieving slot, at its base is 4.5" long. If it were offset by 1/16" in that distance, then 0.0625/4.5 = sin (offset angle). so, (offset angle) = arcsin (0.0625/4.5) = 0.8 degree. It dosn't seem like much and I havn't figured out if the length of the fuse adds any leverage to that small angle. Also by offsetting the thrust angle of the engine by 3 degrees, is that now a combined 3.8 degree? Hal
