Either add nose weight or live with it. I try to balance all my planes to get level flight both upright and inverted at neutral elevator.
Actually upright level flight is very level, mostly through the throttle range. I don't think I'm going to futz with the CG right now. BTW, could too much down thrust cause the same trait?
I'm not too concerned because I like the way the plane hovers and spins right now. I'm guessing that adding some weight up front will make it more difficult to hover.
A larger concern for me is that the MVVS40 with tuned pipe doesn't have enough juice to pull out of a hover. I'm going to try cutting the header 1/2" this weekend and seeing if I can get some more revs outta the setup...
