Myself and two others up here in MN are just about done with Bobcats. This will be my second. I have not called Bob on this issue but the other two have. They were told that the 3301's were fine and that they have over 300 flights with no problems. However I have talked to a BV rep. and he recommended the 9411 conversion. My first Bobcat had a Mercury only pushing about 14-15lb. of thrust. My new one will have a JC p-80 plus at about 20lb. of thrust, so this thread is making me a little nervous. I'd really prefer not to have a servo hanging out of the stab. But it seems better than no plane.
Good Luck!
