The Flywing AS350 470L replicates the distinctive lines of the AS350 Écureuil, also known as the Squirrel or AStar depending on the market. This 470 class scale RC helicopter comes in an RTF version, already assembled, tuned, and equipped with its electronics.
Its main rotor with three quickly removable blades, detailed fuselage, and 810 mm rotor diameter give it a real presence in flight. The model is intended for pilots seeking the realism of a scale helicopter with the electronic assistance of a modern flight system.
ACE Flight Controller with GNSS Positioning
The Flywing AS350 is equipped with the ACE flight controller paired with an M10 GNSS module. The system utilizes multiple satellite constellations, including GPS, GLONASS, and Galileo, to ensure outdoor positioning of the helicopter.
Two main flight modes are available:
- GPS mode: automatic position and altitude hold;
- ATT mode: attitude stabilization for more direct control while still retaining electronic assistance.
When satellite reception is sufficient, Flywing claims a positioning accuracy of:
- ±1.5 m on the horizontal plane;
- ±0.5 m on the vertical axis.
These values depend on GNSS reception conditions, environment, and weather conditions.
Multiple Auto-Return Functions
The ACE controller includes several functions designed to secure the flight:
- auto-return triggered by the pilot;
- return in case of radio signal loss;
- return when the configured low voltage threshold is reached;
- GPS position hold;
- takeoff and landing assistance.
The auto-return brings the helicopter back to the point recorded at takeoff. It is essential to keep sufficient energy reserves, fly within line of sight, and check proper satellite lock before takeoff.
Realistic Turning Behavior
The coordinated turn assistance automatically combines rudder input with the tilt of the helicopter. This allows for smoother trajectories and a turning attitude closer to that of a full-size helicopter.
Various sensitivity settings allow you to adapt the model's behavior to the pilot's skill level and the desired type of flight.
Direct Drive Brushless Motorization
The main rotor is powered by a 3508 brushless motor paired with a 60A brushless controller. This direct drive architecture reduces the number of mechanical transmission components and aims to improve responsiveness and simplify maintenance.
The tail rotor also uses an independent brushless motor.
Up to 20 Minutes of Flight Time
Flight time can reach up to 20 minutes. The actual duration depends on the battery used, its condition, piloting style, wind, and how various flight functions are used.
An RTF Helicopter Almost Ready to Fly
The AS350 comes assembled and tuned with its 2.4 GHz transmitter. For transportation purposes, however, the three main blades must be installed before the first flight.
The battery also needs to be charged, and the safety checks described in the manual must be performed before each use.

Box Contents
The pack includes:
- a Flywing AS350 470L helicopter, assembled and tuned;
- three removable main blades;
- a Flywing 2.4 GHz transmitter;
- a rechargeable 4S 5000mAh battery;
- a battery charger;

Usage Precautions
Despite its GPS assistance and automation, the AS350 is still a powerful RC helicopter with an 810 mm rotor. It is not a toy.
Before each flight, check in particular the installation and locking of the blades, the controls, mechanical linkages, battery charge, and GNSS reception. The automatic functions are pilot aids but do not replace pilot control or the need to follow safety rules.
