I had three oz of weight on the firewall. I didn't realize it was that big of a deal. It seemed like a relatively small amount of weight for as big as this thing is. I wanted to keep the electronics bay really clean and mount everything to it just in front of the rudder servo. When I get back Im gonna recheck things and move the batts around so I dont have to use any dead weight. I have flown much smaller planes with a lot worse cg problems than this, this one seemed unique though. I was just curious to see if this thing should be this sensitive to control inputs. Much more than my Edge?
