Hay Ackii,
I agree...the model does track better with a bit more forward C.G. This C.G. placement has been an on going discussion since the Top Flight first sold the model. Some state the book setting at 5-5/8" is best...but after flying two of these airframes...the best C.G. for me is at 5-3/8". I love how it will grove and get on step much faster with a more forward C.G.
Soft Landings Always,
