FLY The engine radio servos and batteries you use will determine the final weight and locations of equipment Try to balance the model by moving the batteries and receiver before adding any bal last Note Start at recommended CG until you are com fortable with the flight characteristics of the aircraft You may find this a bit nose heavy at first but that 1s fine to start with After you are comfortable adjust the CG to suit your flying style in small steps especially when shifting the CG toward the tail Move the battery or add small stick on weights to the nose or tail as necessary If additional nose weight is necessary we rec ommend moving the engine forward slightly by adding extra spacer or washers to move the C G forward Try this before adding an addi tional weight For aerobatic flying a more aft balance point is better For smooth sport flying or precision pattern a more forward CG 1s better An air craft that is too nose heavy does not fly well and is difficult to land A tail heavy aircraft is uncontrollable and will likely crash Control Throws The amount of control throw should be adjusted using mechanical means as much as possible and then electronically with the radio The control throws are shown in degrees and inches of deflection Aileron throw measured in inches at the widest point of the aileron 92 2 Elevator throw measured in inches at the widest 4 Use the supplied flight control
