Free phone controller
Some of our remote control cars can also be driven from a phone — with a joystick or by tilting the handset, plus lights, sound and smoke controls. Download the free app below, then follow the setup guide.
The app is free. It works only with Wonder Toys cars that support phone control — look for the app badge on the product page.
Tap the Android button above. Your browser saves the LCW_RCcar installer (.apk) to your phone.
Android shows a “File might be harmful” caution for every app installed outside the Play Store. That warning is standard, not a problem with the file — tap Download anyway to continue.
Open the downloaded file. Android asks whether you want to install the application — tap INSTALL, wait a few seconds, then tap OPEN.


On first launch the app shows its service agreement and privacy policy. Tap the blue option (同意并接受) to agree and continue.

On the home screen, tap the left-most car icon to enter phone-control mode. Then tap the Bluetooth button and pair with your car (device name HY_2504). Once it connects, you are ready to drive.

Tap the iPhone button above, or open the App Store and search for “LCW_RCcar”. Then tap the download icon to install it.
Open the app. It shows a service agreement on first launch — tap the blue option to agree and go into the app.

iOS asks whether the app may find Bluetooth devices — tap Allow. Then tap the Bluetooth button in the app to pair with your car (device name HY_2504).

On the home screen, tap the left-most car icon to enter phone-control mode. Your car is now driven from your phone.

Restart your phone and open the app again. That clears the problem in almost every case.
Check that the car is switched on and charged, that Bluetooth is enabled on your phone, and that no other phone is already connected to it. The car appears as HY_2504.
That is the standard caution shown for any app installed outside the Play Store. Tap Download anyway, then install as normal.
