Aside from the servos and wing struts the planes are almost identical. The wingspan, length, wing placement, weight, CG and recommended throws are the same (or very very close). My old one, like the one you have, balanced fine with a SuperTigre 45, and that’s a heavy setup. You asked for a CG… I would put it at 81mm (3.2 in) from the LE of the top wing in the center as p11 of that manual. The control throws shown on the same page should be fine for a first flight also. There were a lot of people using this manual the past year or so to set the CG for this bird.
