Expert Maintenance: Keeping Your TRX-4 Trail-Ready
The rugged nature of rc rock crawlers often leads to the misconception that they are maintenance-free. On the contrary, the "after-care" of your vehicle is what separates a hobbyist from a pro. At AT Models, we believe that a well-maintained truck is a more reliable truck.
The Post-Run Checklist
- Inspect the Portal Portals: These housings contain small gears that work hard. Every few months, check for grease levels and ensure no grit has bypassed the seals.
- Servo Health: The steering servo on the TRX-4 is powerful, but UK mud can put it under immense strain. If you hear a "straining" sound when stationary, check if your steering linkage is blocked by a stray twig or stone.
- Tyre Care: After a muddy session, the foams inside your tyres can become waterlogged if you have vented wheels. Squeeze them out or consider using "closed-cell" foams for better water resistance.
The "Slipper Clutch" Adjustment
The TRX-4 uses a slipper clutch to protect the drivetrain from shocks: like when a wheel gets suddenly wedged between two rocks. If you hear a high-pitched squealing while the truck isn't moving, your slipper may be too loose. Tighten it slightly, but always leave a small amount of "slip" to prevent snapping a driveshaft.
Pro Tip: Cruise Control
Did you know the TRX-4’s TQi radio has built-in cruise control? On long, flat forest paths, set your speed using the throttle, then click the "Menu" button. You can then use the Multi-Function knob to fine-tune your pace, allowing you to walk alongside your truck without constantly worrying about your trigger finger.
