Aircraft Parts

Main Landing Gear Installation

Propeller Installation

Mount the propeller onto the motor shaft and the raised numbers on the propeller should face toward the front of the aircraft. Then secure it with the included M2x4mm screws

Horizontal Tail Installation

Attach the end of the elevator pushrod at the top of the vertical stab into the corresponding hole in the center of the horizontal tail. Connect the plastic pins at the top of the vertical stab into the respective clevises holes at the bottom of the horizontal tail.

Wing Installation

Connect the aileron servo connector to the servo extension installed in the mutli controller and center the wing on the fuselage. Ensure the aileron servo connector is not pinched between the wing and fuselage.

Then attach the wing with the included wing fixing bolts. Do not overtighten the wing bolts, as it may damage the wing or the attachment points in the fuselage.

Eyas II Mini Installation Complete

Control Surface Centering (Aircraft was completely adjusted in the factory setting)

Turn off the transmitter and plug the flight battery into the aircraft (all the servo will return to neutral position automatically) before performing control surface centering.

Aileron Adjustment

Unscrewing the pushrod mounting screw under the wing, adjust the aileron until the control surface is centered, screwing in the pushrod mounting screw after adjustment.

Horizontal Tail Adjustment
Unscrew the pushrod mounting screw on the servo and adjust the horizontal tail until the line on the clevises aligns with the line on the vertical stab as shown, tighten the pushrod mounting screw after adjustment.

Center of Gravity (CG)

An aircraft with the correct CG has its weight balanced on the center of the aircraft for safe and stable flight. The aircraft CG and weight are based on having the recommended battery installed. (7.4V 2S 650mAh 20C Li-Po Battery, 35g)

The CG location is on the carbon tube under the bottom of the wing. Balance the aircraft on your fingertips at the carbon tube and adjust the battery position as needed to get the aircraft to balance correctly.

• If the nose goes down, move the flight battery back until the aircraft balances.
• If the nose goes up, move the flight battery forward until the aircraft balances.

Pre-Flight Checklist

• Always turn the transmitter (required to complete) on first
  Make sure the transmitter controls are neutral, the throttle is at the lowest position and set the THROTTLE

• CUT switch on the transmitter to the RED DOT position
  Plug the flight battery into the aircraft and place it on a level and in an unobstructed open field

• Check the aileron movement
  Push the aileron stick left, left wing will tilt up and right wing will tilt down Push the sileron stick right, left wing will tilt down and right wing will up

• Check the elevator movement
  Push the elevator stick up, the back edge of left and right horizontal tail will tilt down Push the elevator stick down, the back edge of left and right horizontal tail will tilt up

• Check the rudder movement
  Push the rudder stick left to point the nose of aircraft left Push the rudder stick right to point the nose of aircraft right

• Check the Alignment
  Keep the throttle at zero and aileron, rudder, elevator to neutral. All the wing, horizontal tail and vertical fin should align to the aircraft. Adjust the pushrod of the servo if one of them do not align to the aircraft. Refer to the “Control Surface Centering” for more information

If the aircraft control surfaces do not respond as above, DO NOT FLY

Flying Checklist

• Always turn the transmitter (required to complete) on first
  Make sure the transmitter controls are neutral, the throttle is at the lowest position and set the THROTTLE
  CUT switch on the transmitter to the RED DOT position

• Plug the flight battery into the aircraft, place it on a level surface and let it to initialize
  Do not touch the aircraft after pluging the flight battery and let it to initialize. The LED (green) and (blue) on the multi control unit will glow solid. Secure the flight battery with the hook and loop strap, then put back the battery hatch after the aircraft initialized successfully
  Place the aircraft in an unobstructed open field and takeoff with upwind (if there is wind)

• Stand on a safe, unobstructed and well-viewed area
  Set the THROTTLE CUT switch on the transmitter to the GREEN DOT position

• Push the throttle Stick up and push down the elevator Stick, fly the aircraft
  Take off to a suitable height and start to control the two sticks to let the aircraft fly in the desired trajectory

• Land the aircraft
  Unplug the flight battery then turn the transmitter (required to complete) off last

Skill 1: Ensure not to tilt the throttle stick and maintain in the center when taking off It help the aircraft keep steady during the take-off period

Skill 2: During the take-off period, push the throttle higher and pull the elevator lower will shorten the take-off time

Skill 3: Find an unobstructed open field to land the aircraft. Begin the landing by lower the throttle and decending towards the runway Once the aircraft about to touchdown, gently pull back the elevator to raise the nose and flair for a gentle landing

Multi Control Unit Wiring Diagram

Transmitter and Receiver Binding

1. Power off the transmitter and power on the aircraft, the LED (Blue) on the multi control unit (Eyas II Mini) from flashes rapidly to glow solid and the LED (Green) flashes rapidly. which shows the multi control unit is in bind mode
2. Push and hold the rudder trim to the right, then press and hold the power switch of the transmitter.
3. The LED (green) on the multi control unit will glow solid and the transmitter beep one time when binding is complete. Then release the rudder trim button and power switch.

Troubleshooting Guide

Situation: Aircraft does not operate
Solution: Please check the following

Step 1 – Turn the transmitter on first always, then plug the flight battery into the aircraft.
Step 2 – Rebind transmitter to the aircraft (multi control unit green and blue LED will glow solid).
Step 3 – Servo channel connectors must plug in the correct port in the multi control unit.

Situation: Aircraft compatible with other batteries
Solution: The included 7.4V 650mAh 2S 20C Li-ion Battery is highly recommended to use.
The capacity, dimensions and weight for other batteris should be similar to place in the fuselage.

Situation: Motor do not spin after Initialize successfully and servo works normally
Solution: Throttle cut function is activated, refer to the “Flying Checklist” for more information.
