I went to great pains to get 5-3/4 with my OS 160. I don't have a pilot or instrument panel yet. That will cause the c.g. to move back a little. I think I finally know why I almost crashed this thing the first time out. Amateur mistake considering I have 20 years RC experience. What about expo. Do I really need it as high as 70%? I flew my Sukhoi all last season with 0%.

Thanks for the info Randy.
