5. Configuració
As a Plug and Play (PNP) model, the Fms MXS V2 requires you to supply your own radio system (transmitter and receiver), flight battery, and charger.
5.1 Instal·lació i vinculació del receptor
- Install your chosen receiver into the designated compartment within the fuselage.
- Connect the pre-installed servo leads (aileron, elevator, rudder, throttle) to the corresponding channels on your receiver. Refer to your receiver's manual for correct channel assignments.
- Bind your receiver to your transmitter according to your radio system's instructions.
5.2 Battery Installation and Center of Gravity (CG)
- Insert your flight battery (recommended 4S LiPo, 2200-3300mAh) into the battery compartment. Secure it with the provided hook-and-loop straps.
- Ensure the aircraft's Center of Gravity (CG) is within the recommended range specified in the full instruction manual. Adjust battery position as needed. Proper CG is crucial for stable flight.

6. Instruccions de funcionament
The Fms MXS V2 is a 3D aerobatic aircraft capable of advanced maneuvers. Familiarize yourself with basic flight controls before attempting complex aerobatics.
6.1 Comprovacions prèvies al vol
- Check all control surfaces (ailerons, elevator, rudder) for correct movement and throw.
- Ensure the propeller is securely attached and free from damage.
- Verify battery is fully charged and securely installed.
- Perform a range check of your radio system.
6.2 Enlairament
Place the aircraft on a smooth, flat surface facing into the wind. Gradually increase throttle while applying slight up-elevator to lift off. For hand launches, ensure sufficient throttle and a firm, level throw.
6.3 Flight Controls and Aerobatics
The MXS V2 excels in 3D aerobatics. Its wing tip Side Force Generators and upgraded horizontal stabilizers provide superior control for maneuvers like Knife Edge flying, loops, rolls, and inverted flight.
