If you love speeding your RC car around your house, this project is for you. Not only will your car gain a turbo and an emergency brake, but will float, and, for a quick getaway, will have space to store a helicopter! So get building and start racing! You can make this project use only slight modifications to the car and helicopter. You will need to have two remotes in your hand to operate this device, the RC car remote and the helicopter remote.
Step 1: Gather the Materials
You will need: One working RC car (a car with high ground clearance)
One working 3 channel helicopter (helicopters with a tail rotor)
Step 2: Prepare the Vehicle
To prepare the RC car, use a screwdriver to remove the body of the vehicle.
Step 3: Making the Car Waterproof
Use tape to protect all the connections. Then enclose the motor and other parts with tape.
Step 4: Make the Vehicle Floatable
To perform this step, measure the car on a sheet of styrofoam, and cut accordingly to allow the steering and drive to work. You should get a cross-like shape. Tape on securely if you want to remove it someday, or glue if you want it permanent. Add outriggers, if needed, for balance. Add more styrofoam as needed.
Step 5: Attach the Helicopter
Cut a piece if cardboard to fit above the vehicle and tape in place. Place the helicopter in the center of the cardboard. Mark the places where the landing gear touch, then use the knife to make indentions. The helicopter should stay in place while driving, and fly away without the cardboard.
Step 6: Add the Turbo and Brake
This requires slight modification to the helicopter. It can always be reverted. Firmly pull the tail rotor of the helicopter upwards. Pull the motor upwards as well. Rotate the motor to face the back of the helicopter. Use a thin piece of tape to secure in place. Replace the rotor. (To use the turbo, pull the right joystick on the helicopter remote downwards. For the brake, push the joystick upwards. The 'turbo' only works on the car by adding more speed to the motor of the car.) This also helps the helicopter for faster front and back movement.
Step 7: Enjoy!
So there you have it. The ultimate race car you made yourself. So race around your entire house, without having to stop for anything. (To drive it in the water, use the remote normally.)
Step 8: Optional: Add a Camera
If you still have space on your RC car, add a camera. For precautionary reasons, try to use a waterproof camera.
Step 9: Disclaimer
This project worked perfectly for my New Bright Pontiac GTO and my Syma S107g helicopter. I do not assume responsibility for broken cars, leaked batteries, cars that sank, etc. But if this project does work for you, congratulations, and happy driving!
