Tips, tricks and optimizations

Battery optimization

High-quality LiPo batteries with low internal resistance are recommended for optimal performance and flight time. When using 4S 5000mAh batteries, attention should be paid to the weight, since heavy batteries can affect the flight properties.

A good balance between capacity and weight offer 4S 3200-4000mAh batteries for sporty flying or 3S 5000mAh for longer, more leisurely flights.

Flight optimization

Priority: The focus is crucial for good flight characteristics. Experiment carefully with small adjustments to find the optimal behavior for your flight style.

Folding adjustment: The factory settings of the flaps are well suited for most applications. For even shorter landing distances, the flaps can be programmed with a little more rash, which however requires more vertical rudder correction.

Prefabricated: The included optional wings significantly improve the slow flight characteristics and are particularly recommended for landings in limited space.

Maintenance tips

• Regular control of propellers on damage
• Verification of servo-drives on fixed seat
• Cleaning of the engines of dust and dirt after flights on unhardened ground
• Battery care through proper charging and storage
