Tim,

Plans help as they should indicate where the FW should be installed to result in the correct engine incidences.

But you can also use your nice laser incidence meter assuming it has a means to fix it to an engine shaft. Set your fuse datum at 0, stab is probably 0, wing at whatever positive (1 degree I believe or is it 2?), and then, if your FW is still free, mount your engine on to it, the incidence meter to the engine shaft and then move the FW until you've achieved your down-thrust (mark left fuse side for FW position - vertically). Then you rotate your fuse to have the datum again at 0 and figure out down-thrust again - except this time it will convert to right thrust since your fuse is rotated. I find it easier to rotate the fuse for down-thrust rather than up-thrust to produce the required right-thrust, if you follow my meaning.

David.
