I have a YS 110/APC 17X4W with no mods, built to the plans... I did change the tank, and
stretched the tail wheel springs to reduce the tension at full rudder... Also glued in the stab..
and as I always do, I added C.A. to exposed and stress areas of the plane.. I was going to
check the incidence... But it was a no go, So she just got glued together... No problems to
date... I really do not notice any problems on T.O., I guess it does have a bit longer T.O.
run?? But... It flys really nice and lands great so far(65+ flts) it's done all I can make her
do and she does it well.. She does show your "not so smooth moves" [>:]
