EN SAFE® Select Technology (BNF Basic) The BNF Basic version of this airplane includes SAFE Select technology which can offer an extra level of protection in flight. Use the following instructions to make the SAFE Select system active and assign it to a switch. When enabled, SAFE Select prevents the airplane from banking or pitching past predetermined limits, and automatic self-leveling keeps the airplane flying in a straight and level attitude when the aileron, elevator and rudder sticks are at neutral.
EN Ventral Fin Installation 1. Fit the left ventral fin into the fuselage and slide aft to secure. TIP: The gray side should face in, and the detailed side should face out. 2. Fit the right ventral fin into the fuselage and slide aft to secure. Vertical Stabilizer Installation 1. Connect the rudder servo connector to the extension in the fuselage labeled RUDD. Feed the excess servo wire into the fuselage. 2.
EN Receiver Installation (ARF Plus) The Spektrum AR637T receiver is recommended for ths airplane. If you choose to install another receiver, ensure that it is at least a 6-channel full range (sport) receiver. Refer to your receiver manual for correct installation and operation instructions. Installation (AR637T shown) 1. Mount the receiver parallel to the length of the fuselage as shown. Use heavy duty double-sided servo tape. NOTICE: Incorrect installation of the receiver could cause a crash. 2.
EN Battery Installation and ESC Arming Battery Selection A 6S 4000–7000mAh LiPo battery is required. The Spektrum 5000mAh 22.2V 6S 30C LiPo battery (SPMX50006S30) is recommended. Refer to the Optional Parts List for other recommended batteries. If using a battery other than those listed, the battery should be within the range of capacity, dimensions and weight of the Spektrum Li-Po battery packs to fit in the fuselage. Be sure the model balances within the recommended CG range before flying. 1.
EN General Binding Tips and Failsafe • The included receiver has been specifically programmed for operation of this aircraft. Refer to the receiver manual for correct setup if the receiver is replaced. • Keep away from large metal objects while binding. • Do not point the transmitter’s antenna directly at the receiver while binding. • The orange LED on the receiver will flash rapidly when the receiver enters bind mode.
EN SAFE® Select Switch Designation SAFE® Select technology can be assigned to any open switch (2 or 3 position) controlling a channel (5–9) on your transmitter. Once assigned to a switch, SAFE select ON gives you the flexibility to choose SAFE technology or AS3X mode while in flight. If the aircraft is bound with SAFE select OFF, the aircraft will be in AS3X mode exclusively.
EN Control Surface Direction Switch on the transmitter and connect the battery. Use the transmitter to operate the aileron, elevator, and rudder controls. View the aircraft from the rear when checking the control directions. Aileron Stick Ailerons 1. Move the aileron stick to the left. The right aileron should move down and the left aileron up, which will cause the aircraft to bank left. 2. Move the aileron stick to the right.
EN Dual Rates and Control Throws Program your transmitter to set the rates and control throws based on your experience level. These values have been tested and are a good starting point to achieve a successful first flight. After flying, you may choose to adjust the values for the desired control response.
EN Flying Tips and Repairs Consult local laws and ordinances before choosing a flying location. Getting Started Before you fly, range check the radio system. Refer to your specific transmitter instruction manual for range test information. When you first connect the battery to the airplane AS3X will not be active. After advancing the throttle past 25% the first time, the AS3X system will be active and it is normal to see the control surfaces react to aircraft movement.
