 Guy's where is the c/g located on the top flight a r f Nobler as to the manual that comes with it?  Thanks a lot

Gil, it's 2-1/2" back of the leading edge measured next to the fuselage (p. 18).

Tower's web page on the Nobler has the manual available for download. It shows the balance of the model "2-1/2 inches back from the leading edge of the wing on both sides of the belly pan". The cg can be adjusted a quarter inch either way to affect the flying characteristics of the model.

Hope this helps!

   Note that this is a safe starting point, but that very small changes in the CG can make very large differences in the performance and sensitivity, due to the very low tail volume coefficient (short and not much area). The Nobler also changes its performance drastically from the beginning to the end of the flight, as the fuel runs out. When you adjust, adjust in small increments - like 1/4 ounce on the nose and 1/8 ounce on the tail.

    The usual checks on the CG still apply, but it's probably always going to seem a bit nose-heavy at the beginning of the flight, because you won't get through the hourglass reliably with the CG in the ideal position for the beginning.
