2. Operating Instructions
Once assembled and all electronics are properly installed and calibrated, your Yokomo GT1-01 is ready for operation. Always operate your RC car in a safe and open environment, away from people, pets, and obstacles.
- Pre-Run Check: Before each use, inspect all screws for tightness, check battery charge, and verify proper function of steering and throttle.
- Power On Sequence: Turn on your transmitter first, then the receiver/ESC on the car.
- Driving: The direct drive system and semi-slick tires provide excellent performance. Practice gentle throttle and steering inputs to familiarize yourself with the car's handling characteristics.
- Power Off Sequence: Turn off the receiver/ESC on the car first, then your transmitter.
Avoid operating the car in wet conditions or on excessively dusty surfaces, as this can damage electronics and moving parts.
