I have a question about my new Magic extra 300L. I have equipped the plane with the magnum .52 xl engine and standard radio gear. With the battery and receiver as far forward as possible under the hatch in the fuselage, my cg is no where near recommended. It seems that I need to add a lot of nose weight to the plane which I dont want to do. Is it possible to mount the battery further forward without modification? It is a standard 4 cell ni-cad square. Im thinking of upgrading to a 4 cell ni-mh 2700 mah pack, though in a stick configuration. I have read that the recommended cg is too conservitive, but just how far back can I get it and safely fly the plane? I have only read of one person here with the xl-52 in the Extra and would apppreciate his insights on the plane with this particular motor.
