cg problem with superpower f 117 stealth


I have completed my f117 superpower stealth comes in at 14 oz. I have an e-flite park 400 4200 kv inrunner direct drive. with a graupner 5.5X4.3 prop.
built as per instructions. measuring 18 inches from tip on side of wing I can not get the correct cg even with the 1300 mah pack all the way forward
in the nose still tail heavy. Will I have to go to smaller and lighter motor??

You'll either need to go with a lighter motor or a heavier battery, or perhaps some nose weight. You really don't want to fly this one if it's too tail heavy... You might even want to get it closer to 17 inches for the first flight and then adjust back from there.
