5. Operating Instructions

5.1 Pre-Flight Check

• Ensure the aircraft battery is fully charged.
• Ensure the transmitter batteries are installed and have sufficient power.
• Check all control surfaces (ailerons, elevator, rudder) for free movement and correct response to transmitter inputs.
• Inspect the propeller for any damage.
• Perform a range check of the remote control system.

5.2 Flight Modes

The integrated 6-axis gyroscope system offers three flight modes, switchable via the remote control:

• Kutanga Modhi: Provides maximum stabilization and limited control throws for easy and stable flight.
• Yepamberi Mode: Offers moderate stabilization with increased control authority, suitable for pilots gaining confidence.
• Nyanzvi Mode: Minimal stabilization for full control and agile maneuvers, recommended for experienced pilots.

5.3 Take-off and Flight

• Place the aircraft on a flat surface, facing into the wind.
• Slowly advance the throttle (left stick on Mode 2 transmitter) to gain speed.
• Gently apply up elevator to lift off.
• Use the right stick for aileron (roll) and elevator (pitch) control, and the left stick for rudder (yaw) and throttle.
• The Airobatic switch on the remote control allows for performing basic aerobatic maneuvers like loops and rolls with a single button press.
• Flight duration is approximately 7 to 15 minutes, depending on throttle usage.

5.4 Kudzika

• Approach the landing area into the wind.
• Reduce throttle gradually to decrease altitude and speed.
• Maintain control with elevator and ailerons.
• Gently flare (pull up elevator) just before touchdown to ensure a smooth landing.
• Once on the ground, cut the throttle completely.

6. Zvimiro

• Durable EPP Foam: Constructed from robust EPP foam for increased resistance to impacts.
• 6-Axis Gyroscope System: Factory-installed system provides flight stabilization across three selectable modes (Beginner, Advanced, Expert).
• Acrobatic Switch: Enables one-button execution of basic aerobatic maneuvers such as loops and rolls.
• DSMX/S-Bus Connection: Main electronic board includes ports for optional external DSM satellites or S-Bus receivers.
