Forestroke DO NOT ever set the CG for a BH model at the rear most! Its usually wrong!!! Start at 105 mm and even then with the nose about 5 degrees down for the maiden flight. In case the plane is twitchy it will tame her a bit. All my BH planes were set up that way for the maiden and I have never had problems on my maiden flight, it will not be too nose heavy either.

Smartmove - the Extra 300 (60) will balance perfect, you only need to shift the battery to balance her! Its a much nicer plane (my humble opinion).
