HI USE YOUR FINGERSif nose heavy move your battery as far back as it takes to be SLIGHTY NOSE HEAVY-on the CGupside down on a low wing-do not forget to balance the plane left to right -hange the plane by the engine thrust washerbe sure you are not on compression plane should want to come to center-fly level on its own when left right balance is correct
on the first flight - check the balance in the airwhen making your left and right turns (while holding some up elevator ) if the nose drops you need more tail weightadd tailweight at 1/2 oz amounts until she flys level around the cornerswhen inverted you should only need a little up elevator input to hold you levelthen your balance is correct and as it should be
a nose heavy plane will fly-a tail heavy plane WON 'T FLY FOR LONG !! ENJOY GOOD LUCK HAPPY NEW YEAR REGARDS TONY ( flying RC for 20 years )
