BALANCE YOUR MODELNOTE: This section is VERY important and mustnot be omitted! A model that is not properly balancedwill be unstable and possibly unflyable.

D 1. Accurately mark the balance point on the bottom ofthe wing on both sides of the fuselage. The balance point isshown on the plan (CG), and is located approximately 3-1/4inches back from the leading edge. This is the balance pointat which your model should balance for your first flights.Later, you may wish to shift the balance up to 3/8" forwardor back to change the flying characteristics. Moving thebalance forward results in a model that is more resistant tostalls and spins but also may act sluggish and require morespeed for takeoff and landing. Moving the balance aft makesthe model more agile with a lighter and snappier "feel" andoften improves snap roll and knife-edge capabilities. In anycase, do not balance your model outside the recommendedrange.

D 2. With the wing attached to the fuselage, all parts ofthe model installed (ready to fly), and an empty fuel tank,block up the tail as necessary to level the stab.
