Hi ironj21, I have a 6 year old FX46 which still runs like new with an APC 11-5 on the nose. The plane is very fast with this prop so I am interested to see what it will do with an 11-6 and 11-7. I haven't had any problems making smooth landings but thats probably just from lots of stick time. I have 7 planes now and retired 5 or 6 others before that. [8D]
