I thought that looked a bit rearward so looked on here, the measurement you are giving (1/8th of an inch behind LE of wing tube) would equate to something like 173mm, quite a difference, I'm assuming you're right (and also that is where I would expect it be) but can Carf be that wrong?

Phil, Regards to right thrust, it's relatively simple. Just remember the 1/4" differential in 14" equals 1 degree. That is, if you put on a 14" prop and the tips' length difference when measured from the tail post was 1/4", that's 1 degree (close approximation).
