Welcome to the Rlaarlo Engineering Workshop！
Upgrading your RC car can be daunting, but don't fret! With some know-how, anyone can unleash its full potential.
Let Rlaarlo open the doors to the world of remote-controlled car modifications for you!
In this video, we'll show you How to modify the Rlaarlo Supercar AK-917 chassis into a dual-motor version.
Step 1: Gather Parts and Preparation
Parts Needed:
- Dual motor mount
- Batteries
- Dual ESCs
- Elevated steering servo mount
- Chassis plate
- Straps
- Barriers
You can choose to buy the above parts, or you can directly choose the Dual Motor Conversion Parts Set
Tools Needed:
- Hex drivers
- Screwdriver
- heat gun (optional)
- zip ties
Preparation: Ensure all modification parts are ready before starting.
Step 2: Remove Original Components
Motor Mount: Start by removing the original motor mount and replacing it with a dual motor mount. This will enable both motors to provide simultaneous output, enhancing power and speed.
Chassis Layout: Install batteries on either side of the chassis, and place two ESCs in front of the motors to optimize space.
Steering Servo: Relocate the steering servo from the bottom to an elevated position to improve the layout. Secure the batteries with straps and add barriers to prevent movement.
Step 3: Disassemble the Chassis
Chassis Brace: Remove cable ties securing the original cables, unplug all receiver wires, and unscrew the chassis brace.
Steering Servo & Suspension: Remove the steering servo link and the screws securing the front suspension to the chassis plate. Use a heat gun if needed to soften thread glue for easier disassembly.
Components: Remove the ESC, receiver, and other components from the chassis plate. Unscrew the servo mount and remove the steering servo, followed by the center drive shaft.
Motor & Suspension: Unscrew the motor mount cover, remove the rear suspension, and pull out the motor with the motor mount.
Step 4: Install Dual Motor Mount and Reassemble
Dual Motor Mount: Slide the dual motor mount onto the spur gear's output shaft and install the drive cup. Position the rear suspension assembly onto the chassis plate and align the holes before tightening the screws.
Front Suspension & Drive Shaft: Install the front suspension assembly, secure the center drive shaft, and fix the elevated servo mount upgrade part.
Motor Installation: Ensure the motor mount slider is installed correctly, align the pinion gear with the motor shaft, and adjust as needed.
Step 5: Final Adjustments and Securing Components
Gear Adjustment: After installing both motors, turn the gears to adjust the gap between the pinion gears and the spur gear. Secure the battery barriers and connect the ESCs to the motors, positioning the ESCs in front of the motors using double-sided tape.
Chassis Brace & Servo: Install the servo onto the new chassis brace, replace the original chassis brace with the upgraded version, and tighten all screws. Reinstall the servo and servo horn onto the chassis brace.
Wiring: Secure the power switch and receiver, connect the ESC wires using a Y splitter cable, and organize all wires with zip ties. Insert the light wires into the receiver.
Step 6: Testing and Final Checks
Battery Straps & Gear Mesh: Install the battery straps, secure the battery, and power on the system to test the gear mesh by sound. Once satisfied, tighten the motor mount screws.
Steering & Cable Management: Adjust the steering servo link, ensure the wheels are straight, and test the steering movement. Secure any loose cables.
With these steps completed, your AK-917 will have a significant boost in power and performance thanks to the dual motor upgrade. Enjoy your newly upgraded supercar!
