Olympic 2
I have an oly also. It is about 15 years old and still flies awesome. I set up a camera on the underside of the wing and take aerial photos with it. THE CORRECT CG IS ON THE MAIN SPAR.... You can almost always never go wrong by checking the CG on the main spar of the wing. 99 % of the time that is right on . Especially w/ floaters
