Figure 4.2: T3D Remote Controller functions. Key controls include: LED (Light Switch Control), ST.REV (Steering Reverse), TH.TRIM (Throttle Neutral Trim), ST.TRIM (Steering Servo Trim), Power Switch, TH.D/R (Throttle Dual Rate), CH1: ST (Steering), CH2: TH (Throttle), TH.REV (Throttle Reverse).
4.4 Binding the Remote Controller and Car
Your car and remote controller should be pre-bound from the factory. If re-binding is necessary, refer to the specific instructions in the included operating manual.
5. Návod k obsluze
5.1 Zapnutí
- Turn on the remote controller first.
- Poté zapněte vypínač na RC autě.
- Wait for the indicator lights on both the controller and car to show a stable connection.
5.2 Základní ovládací prvky
- Throttle (CH2: TH): Pull the trigger towards you to accelerate forward. Push the trigger away from you to brake, and push further to engage reverse.
- Steering (CH1: ST): Turn the steering wheel left or right to control the car's direction.
- Ořízne: Use ST.TRIM and TH.TRIM to fine-tune steering and throttle neutral positions if the car doesn't drive straight or stops when the trigger is at neutral.
- Dual Rate (TH.D/R): Adjust the maximum throttle output. Lowering this can make the car easier to control for beginners.
- LED světla: Use the LED switch control on the remote to turn the car's lights on or off. The car features a full car linkage lighting system.

6.2 Péče o baterii a její skladování

Figure 6.1: Important battery storage guidelines.
- Always store batteries at approximately half charge (storage voltage) to prolong their lifespan.
- Store batteries in a cool, dry place with minimal temperature fluctuations.
- If not used for an extended period (e.g., 3 months), perform a charge and discharge cycle to maintain battery health.
- Nikdy nenechávejte nabíjené baterie bez dozoru.
6.3 Kontrola součásti
Regularly inspect the following components for wear, damage, or loose connections:
- Hnací ústrojí: Check metal drive shafts, CVDs, and powder metallurgy gears for smooth operation and wear.
- Suspenze: Inspect metal hydraulic shocks and metal arms for leaks or damage.
- Ložiska: Ensure all full car bearings are clean and spinning freely.
- Elektronika: Check all wiring connections to the motor, ESC, servo, and receiver. Ensure the waterproof receiver box is sealed.
- Pneumatiky: Inspect tires for wear and ensure they are securely mounted. The car comes equipped with two sets of tires for different terrains.
