This is the Exact same plane as the Pacific planes yak. If the landing gear is two piece it is the same plane. Go to
www.pacificplanes.com and download the instructions for that plane it has throw and cg recommendations that should work fine for this model too. P.S. If this model does have the two piece gear Make sure you go around all the glue joints of the gear mount pads or you'll lose a pad on a landing and tear up the fuse.
