I bought a MT Magic for the son-n-law this past holiday, and would like someone to tell me where are you mounting the receiver & battery? This is not his first. Setup w/ 46fx 12.25x3.75 apc. The cg, from what read from other threads, is a bit more aft than recommended. What is recommended for moderate to extreme 3D? I read 30-35% aft, is this ture? [sm=confused.gif]
