How to upgrade Orlandoo Hunter A02?

Mar 24, 2026 by mnrccars
Upgrading the Orlandoo Hunter OH32A02 (Pajero) focuses on three main goals: improving durability, lowering the center of gravity (CoG), and increasing climbing performance. Here is the breakdown of the essential upgrades:
 
 
1. Drivetrain & Chassis (Stability & Durability)
  • Metal Transmission Housing: Switching to a CNC metal gearbox case increases weight in the middle of the chassis (lowering CoG) and improves heat dissipation for the motor.
  • Metal Drive Shafts: The stock plastic shafts can twist or snap under high torque. Upgrade to MD5-300 metal CVDs (30mm-35mm range) for a much more reliable power transfer.
  • Alloy Skid Plate & Battery Tray: Adding an alloy center skid plate protects the belly from rocks and adds low-slung weight to keep the tires planted.

2. Suspension & Axles (Traction & Articulation)
  • Metal Axle Assembly: This is the "holy grail" upgrade. Full metal front and rear axles add significant unsprung weight, which is crucial for 1/32 scale crawling. They usually come with full ball bearings for smoother rotation.
  • Threaded Metal Shocks: Replace the stock shocks with ME5-230 alloy shocks. These allow you to fine-tune the ride height and spring tension (using hardened spring kits) to prevent "torque twist" during steep climbs.
  • Counter-Drive Transfer Case: Installing a metal counter-rotation gearbox helps counteract the axial torque that causes the chassis to lean to one side when accelerating.

3. Electronics (Precision Control)
  • Metal Gear Servo: The stock plastic-gear servos strip easily. A metal gear servo provides the torque and durability needed to steer when the tires are wedged between rocks.
  • High-Torque Motor: Depending on your style, a 3000 RPM N20 motor is the sweet spot for slow-speed crawling control. If you want more wheel speed for mud or sand, look toward 500-1000 RPM options.
  • Brushless System (Optional): For elite performance, a mini brushless ESC/motor combo offers incredible low-speed "creep" and massive power, though this requires a full metal drivetrain to handle the stress.

4. Links & Hardware
  • Metal Link Set (SA0033): Replaces the flexible plastic links with alloy rods, reducing play in the suspension and ensuring more consistent wheel placement.
  • Brass Wheel Hexes: Adding brass weights to the wheel hexes is one of the cheapest and most effective ways to stop the A02 from tipping over on side-slopes.
