I would have to agree with the too far back theory. Most planes typically balance out on the spar or in that neighbohood. I am not familaiar with the SkyShark, so it is possible that the balalnce point is where they say, however you might want to drop a dime and call them to confirm it. Other than that I would go with the move it forward as you mentioned as a nose heavy plane will fly and then it can be adjusted to suit your needs. Good Luck, Dave
