It was designed for something like a BGX---I would consider sweeping the wings to get the CG back and or increasing the nose length--to make any balancing weight more effective---having the motor--gear and the booms with horizontal stab back there makes it in need of nose weight---I built this for a company in Georgia-it suffers from the same problems because of the design--it however- has a large lifting surface so the added weight wasn't a problem.
