Answer: Most pilots report an optimal ratio with a 4S 4000mAh LiPo battery. This provides sufficient performance for most flight maneuvers while at the same time good flight time of 12-15 minutes. For maximum performance, we recommend a 6S 5000mAh battery, which is correspondingly more expensive and makes the model a little heavier.

Problem: Instability in wind

Solution: With stronger wind, the model can become somewhat unstable despite its size. The following measures have proved successful:

• Focus easy (3-5mm) move forward
• Increase Expo values to 40% for gentler control
• Increase speed of flight
• With strong wind the flaps enter to reduce the wind attack surface

Question: Is a special transmitter required?

Answer: The PNP model is delivered without transmitter and receiver. It is compatible with all common RC systems as long as the receiver has at least 6 channels. For full functionality we recommend an 8-channel receiver to be able to control the flaps and lighting separately.

Problem: Difficulties in the assembly of the chassis

Solution: The mounting of the suspension suspension can be challenging for beginners. Follow these steps:

1. Turn the fuselage up with the bottom and fix it with foam
2. Guide the suspension struts into the mount
3. Connect the springs to the axes by hooking the open spring ends
4. Attach the spring holder with the M3 screws and washers
5. Pump the tires to 135mm diameter on

Question: Suitability for beginners?

Answer: Although the model has relatively good flying characteristics, we do not recommend it for absolute beginners. Pilots should have already gained experience with simpler models. Advanced beginners will appreciate the stability and failure of the model.
