The flash is a very forgiving airframe, but at the same time creep back on the cg til you trime the flash so it will fly hands off right side up or up side down. Then you will have no down elev. and possibly a little up elevator at slow flight full flaps ( 45 degrees is were i'm at) . If you deploy the flaps at medium speeds the flash might climb a little but as landing speed is established the plane will sink very nice on final. My flash weight is 25.5 lbs uat filled with a ram 1000. This might change with the lighter turbines. The key is trim flight the flash for right side and upside down level flight with the cg position then worry about the mix elev. to flap. Right now i'm flying no elev. mix with flaps on landing.
