4. Battery Charging and Installation
Before first use, fully charge the included Lithium Polymer battery using the provided charger. Refer to the charger's instructions for safe charging practices. Once charged, install the battery securely in the aircraft's battery compartment.
5. Transmitter Setup
Ensure the transmitter has fresh batteries. Power on the transmitter before powering on the aircraft. Bind the transmitter to the receiver if not already bound (refer to the physical manual for binding instructions).
Operating Instructions
The Piper PA-18 Super Cub is equipped with the Reflex V2 stabilization system and other features for enhanced flight control.
Pre-Flight Checks
- Verify all control surfaces (ailerons, elevator, rudder) move freely and in the correct direction relative to stick inputs.
- Check battery levels in both the aircraft and transmitter.
- Ensure the propeller is securely attached and free from damage.
- Confirm navigation and landing lights are functional.
Flight Modes (Reflex V2)
The Reflex V2 system offers different flight modes (e.g., Stabilizer, Dynamic, Off) to assist pilots. Consult the physical manual for detailed instructions on switching between modes and their specific characteristics.
Takeoff
Choose an open, clear area for takeoff. Advance throttle smoothly and apply slight up-elevator as the aircraft gains speed.

Flight Control
Use the transmitter sticks to control the aircraft. The Reflex V2 system will provide stability, especially in windy conditions.
Reverse Propeller Function
This model features a propeller that can be operated in reverse, offering more flexible and versatile control, particularly useful for short landings or ground maneuvering.

Landing
Approach the landing strip at a controlled speed. Reduce throttle and gently flare the aircraft just before touchdown. The oversized tires are designed to handle various terrains.
Maintenance
Regular maintenance ensures the longevity and performance of your RC airplane.
- Cleaning: After each flight, wipe down the airframe to remove dirt and debris.
- Propeller Inspection: Check the propeller for any nicks, cracks, or damage. Replace if necessary.
- Control Surface Check: Ensure all hinges and linkages are free-moving and secure.
- Battery Care: Store LiPo batteries in a cool, dry place at storage voltage. Do not overcharge or over-discharge.
- Motor and ESC: Periodically check for any signs of wear or overheating.
- Landing Gear: Inspect the CNC metal landing gear for any bends or damage, especially after rough landings.
