RE: Help With Warbird Wing/Stab Incidence
I have the same problem with my second Sportsman Aviation Spitfire. The first one had a YS FZ91, that one required some weight in the tail to balance the cg and flew perfect. The second one has an OS91fx and this one needs lots of down trim to fly level. Down thrust did not help, zeroing 2 degrees of wing incidence did not help; I moved the cg forward by 10mm (using an aluminium spinner),now making perfect takeoffs and landings a breeze, still need down trim for flying. I resigned and set my down trim with my TX subtrim; the good thing is, I am now having fun flying it.
