Sounds like it's slightly nose heavy with too much down thrust to me.... The nose heavy requires some up elevator to hold level, but when inverted the downthrust becomes up thrust, pulling the nose up.
Just one theory...

That is kinda what I was thinking also. At what throttle setting should I be checking this? I read someplace that when upright I should have to pull up ele. just a little and when inverted I should have to push down ele. a little bit. Does that sound correct or do I want to be able to fly upright and inverted with no ele. input. If this is the case then at what throttle setting. If I do need to ajust the down thrust is there some way to calculate this and are there shims available. Thanks for the help.
