Key Takeaways
- Flywing’s ACE flight controller combines M10 multi-mode GPS and a barometer to provide position hold, self-levelling and return-to-home assistance.
- GPS assistance makes a scale rc heli approachable for beginners: in GPS hold, releasing the sticks lets the model stabilise and hover.
- The range includes five scale helicopters and the non-scale FW450L trainer, each with a different look and set of features.
- All six models are in stock now at AT Models.
- Matching spares and expert after-sales advice matter just as much as the first flight.
What does the ACE flight controller actually do?
Could a scale helicopter really be a first model? With the right assistance, yes. Traditionally, a detailed scale fuselage meant a less forgiving first step than a basic trainer. Flywing’s ACE system helps change that by supporting the pilot while they learn to manage a helicopter’s controls.
The controller uses an M10 multi-mode GPS receiver to establish the model’s position, while a barometer, a sensor that measures changes in air pressure, helps it judge altitude. Together with onboard stabilisation, these components support several useful flight functions:
- GPS position hold: the controller counteracts drift and helps hold the helicopter’s position. In GPS mode, ease off the sticks and the model can settle into a hover.
- ATT self-levelling: ATT is an assisted mode that helps return the helicopter to a level attitude. It’s useful as you learn, but it isn’t the same as GPS position hold.
- Return-to-home: a switch command brings the model back towards its recorded take-off point. The system also supports automatic low-voltage return and landing.
- Three sensitivity levels: switch between soft, standard and sport responses to suit your confidence and preferred control feel.
- Coordinated turns: the controller assists the model’s turning response by coordinating control inputs, helping turns look more natural.
- Soft take-off and landing: assisted power and control behaviour helps make the start and finish of a flight less abrupt.
Automatic figure-8 and circle patterns add a display-friendly option on the UH-1 Huey. They’re handy when you want a smooth, repeatable flight path for spectators at a club day or event.
Pro tip: GPS is assistance, not a substitute for a pilot. Choose a clear flying area, allow the system to establish a reliable GPS lock before take-off, keep the helicopter in sight and know which mode you’ve selected.
Meet the six Flywing models
Which one looks like your kind of helicopter? These six models share the appeal of GPS assistance, but their scale subjects, battery capacities and details differ. Each model below is in stock now.
1. FW450L ACE GPS: the trainer with room to progress
The FW450L is the range’s non-scale, 450-size GPS trainer. It trades a scale fuselage for a practical platform with Smart Acro mode for pilots ready to explore more lively flying. Its brushless main and tail motors run from a 4S LiPo battery, driven through coreless metal-gear servos, and the included 5000mAh pack is listed for approximately 25 minutes of flight. In GPS hold, hover accuracy is quoted at roughly ±1.5m horizontal and ±0.5m vertical — tight enough that the model stays put while you think about your next move.
A quick-release canopy gives access to the battery and electronics. One useful setup detail: the tail boom ships detached, so you’ll need to fit it and connect the tail motor before flying. Allow around 15 minutes for this job.
Choose from orange, green or white:
2. UH-1 Huey V4 ACE GPS: unmistakable utility-helicopter character
The UH-1 Huey brings a classic military silhouette to GPS-assisted scale flying. Its metal rotor head and 3D-printed detailing add character, while the receiver comes pre-fitted. The model has an 810mm main rotor diameter, 370mm main blades and a 125mm tail rotor, driven by a 3508 brushless main motor running on 16V (4S) through a 60A dual ESC — an electronic speed controller, the component that regulates motor power. The included 4S 3000mAh LiPo is listed for over 20 minutes of flight, and the model weighs approximately 869g.
Automatic figure-8 and circle modes make this a natural choice for pilots who enjoy smooth, presentable display flights as much as scale detail. Available in grey or red:
3. Bell 206 V4 ACE GPS: a vivid four-blade classic
This red Bell 206 pairs a familiar light-helicopter shape with a four-blade metal quick-release rotor head. A quick-release head lets the rotor assembly be removed more conveniently for handling or transport. The included 4S 3000mAh LiPo is listed for approximately 22 minutes of flying.
It’s a good fit if you want a bold scale model with a multi-blade rotor disc and the familiar support of GPS hold and self-levelling.
4. Bell 407 ACE GPS: air-ambulance styling and working lights
The Bell 407 stands out with its air-ambulance style livery, four-blade metal quick-release head and working navigation lights. Its included 4S 5000mAh LiPo is listed for approximately 20 minutes of flight. Choose it for a recognisable utility-helicopter look and a scale finish that’s easy to appreciate on the ground as well as in the air.
5. Bell 412 V4 Military Rescue: purposeful rescue styling
The Bell 412 V4 brings a military rescue livery and a four-blade quick-release rotor head to the range. It includes a 4S 3000mAh LiPo, with approximately 22 minutes of flight listed. Consider this one if you favour a larger-looking, working-aircraft presence and a detailed rescue theme.
6. MH-60T Jayhawk ACE GPS: Coast Guard-inspired detail
The MH-60T Jayhawk stands apart with its US Coast Guard style livery, shock-absorbing scale landing gear and red, green and white navigation lights with a double-flash pattern. It also has a four-blade metal quick-release head. The included 4S 5000mAh LiPo is listed for approximately 18 minutes of flight.
Choose it if the rescue-helicopter silhouette and illuminated scale details are the main attraction.
Two blades or four: what changes?
Does a four-blade head simply mean more lift? Not necessarily. Blade count is part of the whole rotor design, including blade shape, rotor speed and setup. The choice most visible to a modeller is often about scale appearance and flight character.
A two-blade head has a simpler, uncluttered rotor disc and often suits a more traditional or lighter scale look. A four-blade head creates a fuller disc that can look closer to many full-size utility helicopters. It may also produce a different, often smoother-sounding rotor beat. Actual sound and flight feel depend on the model and setup; extra blades don’t automatically mean greater efficiency.
A quick-release head is practical, too. It can make packing or access more convenient, and helps when you need to handle the rotor assembly for maintenance. Always follow the model’s instructions when removing or refitting it.
Scale detail and spares: support beyond the first flight
What happens after a hard landing or a routine service? A scale helicopter is a working model, not just a display piece, so it pays to know where to find compatible parts.
For the Bell 206 and UH-1, AT Models stocks the Flywing DFC pitch linkage FW-FS31 and 3D-printed parts set FW-FS50. These model-specific components complement the 3D-printed detail fitted to the Huey.
The wider Flywing spares category includes parts such as main gear FW-FV305, tail blade FW-FV315, rotor holder FW-FV302, H041 servo FW-FL446 and screw bag FW-FV329. Browse the dedicated UH-1 Huey spares page to match parts to your model, and check the wider Flywing range for Bell 206 components. The Flywing 4S 5000mAh spare LiPo FW-FL439 is another option to check for compatibility with your helicopter.
For help locating a suitable part, use AT Models’ Parts Finder. Our dedicated helicopter specialists can advise on matching components, supported by an extensive inventory under one roof and long-term after-sales support.
