FLYWING FY-RC02: One Transmitter. More Control. Smarter Flying | Stirlingkit

Monitor live flight data, review what happened after every flight, adjust settings at the field, and run your whole FLYWING fleet from one transmitter.

Have you run into any of these?

You’ve bought so many transmitters, one for each helicopter, that they no longer fit in the cabinet. Or the helicopter is in the air and you have no idea what state it’s in. Or the motor cuts out mid-flight and nobody, you included, can say why. Or you spot something to adjust at the field, and the only way to do it is a laptop back home.

At Stirlingkit, we’re flyers too, so we know how annoying these are. We’ve been listening to what you tell us, and we’ve passed it on to FLYWING again and again. The good news: FLYWING has built the FY-RC02 Smart Telemetry Transmitter to take on exactly these problems. It is not sold separately. It comes standard with select FLYWING RTR helicopters, and the compatibility section below lists which ones.

1. See it and hear it: know what your helicopter is doing

The helicopter starts to climb, or slide toward the trees. The LED on the fuselage is too small to read from where you stand, you’re nervous, and your thumb drifts toward the kill switch. Is it the GPS? The compass? The battery?

With the FY-RC02, you don’t have to guess. Telemetry means the helicopter sends its status back to your transmitter while it flies. The FY-RC02 shows it in real time on a 2.8-inch color display, organized into five main screens. The data includes:

• Battery voltage and current
• GPS satellite count and coordinates
• Altitude, speed and flight angles
• Vibration and magnetic interference
• Rotor speed, temperature and stability
• Signal strength, flight mode, flight time and error alerts

Which values appear depends on the helicopter and its electronics, so some readings may not be available on every model.

Then there is the voice. When the helicopter is fifteen meters away and the LED is a tiny dot, you shouldn’t have to decode blink patterns. A voice tells you the battery is low or satellites are lost, so your eyes stay on the helicopter. The display and voice alerts switch together between Chinese, German, English, French and Japanese. Nothing to program, and no audio files to import.

It helps in the everyday moments too. You touch down a little hard, and the next takeoff sounds louder: the vibration reading gives you something concrete to check. The helicopter won’t find satellites: with the satellite count, helicopter status and compass warnings on screen, you can tell whether it’s the GPS, a kill switch that isn’t in the right position, or a slightly disturbed compass.

2. Review it: find out why something went wrong

The motor stops in mid-air. Was it a bumped switch, or a fault? Without a record, everyone is guessing, and it’s easy to assume the aircraft is to blame.

The FY-RC02 records your last 20 flights, with up to 256 entries per flight: GPS satellite count, battery level, error information and your control inputs. Logs stay on the transmitter, cannot be exported or deleted, and the oldest are overwritten automatically.

If something goes wrong, open the log, take a photo of the screen and send it to our after-sales team. They will check it, so you and we start from data instead of memory.

3. Tune it at the field, no laptop needed

Picture a morning at the field. The nose wanders a little, or the compass needs another calibration. With a computer-based setup, that means packing up and heading home. Here, you open the menu, change it, and keep flying.

On the FY-RC02, you can set compass calibration, maximum positive and negative collective pitch, swashplate leveling, throttle, tail gain, swashplate pitch and roll gain, and low-battery return straight from the transmitter menu.

Compass calibration is a classic example. Many pilots have calibrated several times, been told it succeeded, and still seen a red LED the moment the helicopter is set on the ground. It’s easy to blame the flight controller. Sometimes the cause is the spot itself, such as nearby metal, and the magnetic interference reading on the FY-RC02 screen helps you tell the difference.

Calibrate in the right order. Set up and calibrate the transmitter first, and check that the stick directions match the setup screen. Then move on to settings such as the swashplate. If the swashplate is set first, two reversed settings can cancel each other out: the sticks seem to behave, but once the flight controller starts correcting the helicopter, it flies wrong.

4. One transmitter for your whole fleet

Maybe you have a cabinet full of transmitters, one for every helicopter. When it’s time to fly, you grab the matching one, because nobody wants to rebind and reconfigure everything just to switch aircraft.

RTR helicopters arrive with the FY-RC02 already bound, so you can fly right away. Each additional helicopter only needs to be bound once. After that, the FY-RC02 remembers it, and one transmitter can hold up to about 1,000 helicopters. To fly a different one, choose its model in the menu and its parameters load into the flight controller. No second transmitter, no starting over.

That saves money, because you don’t need a transmitter for every helicopter, and it saves time, because there is no rebinding or reconfiguring each time you switch.

Before: it’s a free Saturday and you want to fly two helicopters. That means two transmitters in the bag, and a quick check of which one belongs to which.

Now: one transmitter. Fly the first, pick the second in the menu, and keep going.

Adding another helicopter is quick, and the steps are here if you need them.

Designed to make learning easier

A first flight is mostly nerves. These features give a new pilot, and whoever is standing next to them, something to lean on.

• GPS Hover: let go of the sticks and the helicopter brakes and holds its position and altitude, so a first flight feels much calmer.
• Trainer mode: connect two FY-RC02 transmitters with a 3.5 mm trainer cable. The instructor can take over at any time with the trainer switch, which is shared with the Route switch, and a “Trainer Flying” voice alert plays.
• Simulator: the same 3.5 mm port outputs standard PPM data for a simulator dongle (bought separately), so you can practice at home.

The FY-RC02 offers up to seven flight modes, depending on the helicopter, so you can move from a calm GPS hover toward more hands-on flying as your skills grow.

The front three-position switch selects GPS, Freedom (Attitude) or a custom ACRO slot. In the custom slot you can assign Attitude, Manual, 6G or Smart Acro, so the modes you use most stay one flick away.

With a compatible ACE flight controller, you also get one-touch circle and figure-8 flight patterns. Always fly within visual line of sight and follow your local regulations.

Built for long days at the field

• Metal gimbals: a rigid metal frame, full-bearing construction and high-precision RDC50 potentiometers for smooth sticks and crisp centering.
• 12 channels and a 2.8-inch color display.
• Foldable antennas for easier carrying and storage.
• About 2,000 m of control range in ideal conditions.
• Up to about 7 hours of battery life: a built-in 3.7 V, 5000 mAh lithium-ion battery that charges in around 3 hours with a 5 V / 2 A supply.
• USB Type-C port for firmware updates, so the transmitter can pick up newer models and features.

For 3D stunt helicopters: a gentler way into 3D

Scale helicopters such as the AW109 and Bell 206 work with the FY-RC02, but they don’t have the stunt functions below. On 3D stunt helicopters, such as the FW450L V3, the FY-RC02 adds a gentler way into 3D for beginner and intermediate pilots who are curious about it but don’t want a steep learning curve.

Many pilots reach a point where hovering feels comfortable and 3D starts to look tempting. The hard part is inverted flight: the controls feel reversed, there is little room for error, and one wrong stick input can end the flight. That is where a lot of pilots stop, or only practice on a simulator.

Easy Inverted 3D takes the hard part away:

1. Press L-GEAR. The helicopter rolls itself over into an inverted hover.
2. It holds its position by GPS, so it stays put instead of drifting away.
3. Fly it just like upright GPS flight. Push the throttle up to climb.

It is a friendly way to get your first taste of 3D, without the white-knuckle learning curve.

When you’re ready for more, Smart Acro 3D is the next step. The helicopter hovers by GPS like normal. Push a stick past the threshold (80% by default) and it flips; push fully to roll in any direction. Let go, and it recovers to a position and altitude hold. If you let go close to inverted, it stays in an inverted hover, and another full push completes the half roll.

How the FY-RC02 compares

Most helicopter pilots start with the basic transmitter that comes in the box, or move to a general-purpose open-source radio. Here is how the FY-RC02 differs.

Open-source radios are powerful and flexible, and they work with many kinds of aircraft. The FY-RC02 trades that breadth for a setup made specifically for FLYWING helicopters, so the features above work without extra programming. Features such as automatic flight routes and one-touch inverted flight need the FY-RC02 together with a compatible FLYWING ACE V1.3 flight controller.

Compatible FLYWING helicopters

The FY-RC02 is not sold separately at this time. It comes standard, together with one flight battery, in the RTR (ready-to-fly) version of FLYWING 470-class helicopters.
