There was a review done by RC Universe about the Showtime plane. In the review there were pics of the inside of the plane showing the fuel tank moved back up against the fiberglass wing tube holder. Mounting directions from the factory have the fuel tank up in the nose against the firewall...and the CG measurement being 7 1/16" from the wing tip. My question is...with the fuel tank being moved back, have i changed the CG significantlly enuff that the 7 1/16" from the wing tip is no longer an accurate measurement for balancing the plane? Could really use some info from someone that has the same fuel tank location set up...Thanks.
