Function Description:
The Traxxas T-Maxx 3.3 is a Ready-To-Race® (RTR) monster truck designed for exciting off-road action. Its primary function is to provide a powerful and durable remote-controlled driving experience. The truck is equipped with a TRX 3.3 Racing Engine, a two-speed transmission, and a TQi 2.4GHz radio system with Traxxas Link™ Model Memory. The EZ-Start® electric starting system simplifies engine ignition. The vehicle is designed to handle various terrains, from smooth tracks to rough off-road conditions, and offers extensive tuning capabilities to customize its performance characteristics.
Important Technical Specifications:
- Engine: TRX 3.3 Racing Engine. This is a .20 cubic inch (3.3 cubic centimeter) nitro engine featuring ABC (aluminum, brass, chrome) construction for precise piston/sleeve fit and optimal compression. It's designed for broad, linear power delivery and ease of tuning.
- Fuel: Requires model engine fuel with 10%, 20%, or 33% nitromethane content. Traxxas Top Fuel™ is recommended for consistent performance and engine life. The engine is optimized for 10-20% nitro, with 33% nitro suitable for racing.
- Starting System: Traxxas EZ-Start® Electric Starting System. This system includes a hand-held control unit with a 7.2-volt rechargeable NiMH battery pack, an on-board motorized starter, and automatic glow plug heating. It features Smart Start™ protection circuitry to prevent motor damage.
- Radio System: Traxxas TQi 2.4GHz Transmitter with Traxxas Link™ Model Memory. This 3-channel radio system offers spread spectrum technology for superior interference resistance. It includes adjustable Exponential, End Points, Sub-Trims, Steering and Braking Dual Rate, and a Multi-Function knob that can control various advanced functions, including Traxxas Stability Management (TSM). The Traxxas Link App (available for Apple and Android devices) provides a graphical user interface for tuning and real-time telemetry data (speed, RPM, temperature, battery voltage).
- Battery (EZ-Start): 7.2-volt rechargeable NiMH battery pack (included).
- Batteries (Transmitter): 4 AA alkaline batteries (sold separately).
- Batteries (Receiver): 4 AA alkaline batteries (sold separately), with an optional NiMH rechargeable RX Power Pack battery (part #3037) available for upgrade.
- Air Filter: Two-stage high-performance air filter with pre-filter and primary filter elements for maximum filtering efficiency.
- Carburetor: Slide carburetor design with high-speed and low-speed mixture needles for precise air/fuel ratio control.
- Transmission: Two-speed transmission with adjustable shift points and an adjustable Torque Control slipper clutch.
- Brakes: Disc brake system with adjustable shoulder screws for pad gap.
- Suspension: Oil-filled Ultra Shocks™ (oil dampers) with adjustable mounting positions and clip-on spring pre-load spacers for ride height and spring rate tuning. Factory-filled with 40W silicone shock oil.
- Chassis: Designed for durability and performance.
- Wheels/Tires: Factory-glued tires to rims.
- Dimensions (Model 49077-3): Not explicitly stated in the provided excerpts, but implied to be a large monster truck.
Usage Features:
- Quick Start Guide: A streamlined path to get the model running quickly, covering essential steps like battery charging, installation, radio system setup, engine starting, break-in, and initial tuning.
- TQi Radio System: User-friendly transmitter with advanced tuning capabilities. The Multi-Function knob can be programmed for various controls, including Traxxas Stability Management (TSM), which aids in maintaining control in low-traction situations and improves braking.
- Traxxas Link App Integration: Allows for intuitive tuning and real-time telemetry monitoring (speed, RPM, temperature, battery voltage) via a smartphone or tablet, enhancing the user experience with graphical interfaces.
- EZ-Start® Electric Starting System: Simplifies engine starting with a push-button operation, eliminating the need for a separate glow plug igniter.
- Adjustable Drivetrain: The two-speed transmission's shift point can be adjusted to optimize for acceleration or top speed. The slipper clutch is adjustable to limit torque output to the wheels, preventing wheelspin and protecting gears.
- Suspension Tuning: Multiple shock mounting positions, adjustable spring pre-load spacers, caster, and camber adjustments allow for fine-tuning the suspension to suit different terrains and driving styles.
- Engine Tuning: High-speed and low-speed mixture needles on the carburetor allow for precise adjustment of the air/fuel mixture to optimize engine performance based on atmospheric conditions (temperature, humidity, altitude) and fuel type. An idle speed screw controls the engine's idle RPM.
- Model Memory: The TQi radio system automatically stores settings for up to 30 different models, recalling them when a bound receiver is switched on. Model Lock feature prevents accidental deletion of model settings.
- Fail-Safe: Built-in fail-safe function returns the throttle to neutral in case of signal loss or interference, preventing runaway.
Maintenance Features:
- Engine Break-in Procedure: A specific, detailed break-in process (5 tanks of fuel) is outlined to ensure the TRX 3.3 Racing Engine achieves its best performance and longest life. This involves varying and limiting engine speed during initial runs.
- Air Filter Maintenance: Critical for engine longevity. The pre-filter element requires cleaning and oiling every hour of run time, and the primary filter every 3-4 hours. Detailed instructions for cleaning and oiling are provided.
- After-Run Maintenance: Essential for preventing corrosion on internal engine components. This procedure involves pinching the fuel line, emptying the fuel tank, running the engine dry, and applying after-run oil (or WD-40™) to lubricate internal parts before storage.
- Periodic Inspections: Regular checks for loose/missing screws, cracked/damaged parts, cut/loose wiring, kinked fuel lines, and fuel leakage are recommended after each running session.
- Slipper Clutch Pad Replacement: Friction material in the slipper clutch should be replaced if its thickness falls below 1.8mm.
- Engine Component Replacement: The manual notes that critical engine components (crankcase, crankshaft, bearings) are high-quality and designed to outlast multiple sets of reciprocating assemblies (pistons, sleeves, connecting rods, wrist pins), which can be replaced as needed.
- Troubleshooting Guides: Instructions for clearing a flooded engine, freeing a piston stuck at Top Dead Center (TDC), and addressing radio system issues (e.g., weak receiver batteries, link failure) are included.
- Technical Support: Traxxas offers toll-free technical support, email support, an online community, and a full-service repair facility.
- Online Registration: Encourages product registration within 10 days of purchase for better customer service.
