EN Thank you for purchasing the E-flite® UMX™ Yak 54 180 ultra micro airplane with which you’ll enjoy a bold new level of aerobatic performance. No other aerobatic design meets the challenge and demands of precision and 3D versatility like the Yak 54 can. Recognized early on by the father of 3D, Quique Somenzini, his Yak 54 concept ushered in a new era of RC aerobatic agility that’s now possible to experience in small flying spaces indoors and out.
EN Preflight Checklist 1. Charge flight battery. 6. Set dual rates and expos. 2. Install flight battery in aircraft (once it has been fully charged). 7. Adjust center of gravity. 3. Bind aircraft to transmitter. 4. Make sure linkages move freely. 5. Perform Control Direction Test with transmitter. 8. Perform a radio system Range Check. 9. Find a safe and open area. 10. Plan flight for flying field conditions.
EN Battery Charging Your aircraft comes with a 2S 7.4V 150mAh 45C Li-Po battery and a 2S 7.4V DC Li-Po battery charger that requires a 12V (11V–14V) DC power source. Refer to the charging warnings. It is recommended to charge the battery pack while you are inspecting the aircraft. The flight battery will be required to confirm proper aircraft operation in future steps. Battery Charging Process NOTICE: Charge only batteries that are cool to the touch and are not damaged.
EN Low Voltage Cutoff (LVC) When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The aircraft’s ESC protects the flight battery from over-discharge using Low Voltage Cutoff (LVC). Once the battery discharges to 3V per cell, the LVC will reduce the power to the motor in order to leave adequate power to the receiver and servos to land the airplane. When the motor power decreases, land the aircraft immediately and replace or recharge the flight battery.
EN ESC/Receiver Arming, Battery Installation and Center of Gravity CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement. 1 Arming the ESC/receiver also occurs after binding as previously described, but subsequent connection of a flight battery requires the following steps. AS3X The AS3X® system will not activate until the throttle stick or trim is increased for the first time.
EN Side Force Generators (SFGs) Installation Side Force Generators add side force in all flight attitudes, increase rudder authority and make a variety of aerobatics possible. 1. Slide each SFG in the respective channel on the leading edge of the wing. NOTICE: Install the SFGs vertically on the wing. Failure to install the SFGs at a 90º angle may result in incorrect flight performance. 2.
EN Control Centering Before the first flights, or in the event of an accident, make sure the flight control surfaces are centered. Adjust the linkages mechanically if the control surfaces are not centered. Use of the transmitter sub-trims may not correctly center the aircraft control surfaces due to the mechanical limits of linear servos. 1. Make sure the control surfaces are neutral when the transmitter controls and trims are centered. The transmitter sub-trim must always be set to zero. 2.
EN DX4e and DX5e Expo Activation and Deactivation If you plan to fly your aircraft with a DX4e or DX5e, activate Expo for the best feel. Disconnect the battery from the aircraft before activating the Expo feature in your transmitter. Once Expo is activated, it will remain activated for subsequent power cycles of the transmitter. Once Expo is deactivated, it will remain deactivated until it is activated again. DX4e (Modes 1 and 2) Activate and Deactivate Expo 1.
EN Flying Tips and Repairs We recommend flying your aircraft outside in no greater than moderate winds, or indoors in a large gymnasium. Always avoid flying near houses, trees, wires and buildings. You should also be careful to avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields. Consult local laws and ordinances before choosing a location to fly your aircraft.
EN Power Components Service Disassembly CAUTION: DO NOT handle the propeller while the flight battery is connected to the ESC. Personal injury could result. C Propeller 1. Remove the screw (A), and propeller (B) from the prop adapter (C). A B Motor NOTICE: Removing tape or decals can damage paint on your aircraft. Avoid pinching or otherwise damaging any wires when opening or closing the fuselage. 1. Cut through the tape and decals on the fuselage, then remove the upper fuselage. 2.
