Thank you all for your input, very good information and I appreciate everyone that responded.
I will add some down thrust as this is not included in the default build - when trimmed and cut the throttle the plane does not dive.
I built the version of the wing that has the lesser amount of dihedral, I was pretty happy with how it flew the first time.
I will add more rubber bands, I must not have used enough today, I do recall using more the first time I flew it compared with today's flight.
Regarding the CG, the wing cord is 12", that should equate to a 3" CG then. Any idea why such a large discrepancy between this calculation and what GP calls for? Just trying to understand why this would be.
