Precision upper plate for TB-04 rear gearbox

This CNC-style aluminium upper plate is a direct RC replacement for the TB-04 platform, engineered to increase rear gearbox rigidity and reduce deflection under torque. The design focuses on mechanical accuracy to maintain alignment of the rear drivetrain rather than cosmetic changes.

Compatibility covers TB-04 chassis family mounting patterns as indicated in the product naming. The plate integrates with the original TB-04 gearbox assembly and mounting hardware and is suitable for setup work where consistent gear mesh and drivetrain geometry are required for performance tuning.

Recommended installation follows standard RC workshop protocol: confirm precise hole alignment, use correct screw engagement depth, apply appropriate thread locking where needed, and verify gear engagement after securement. These instructions target RC model use only.

What mounting checks should I make before fitment?

Measure and confirm the gearbox mounting hole pattern against the plate, ensure mating surfaces are clean and flat, and test-fit fasteners to confirm correct engagement depth.

Does the plate alter gear mesh settings?

The plate stabilises gearbox positioning which can affect gear mesh; fit loosely, rotate drivetrain to settle gears, then torque fasteners while monitoring backlash to achieve correct engagement.

Recommended fastener practice for durability?

Use the correct screw lengths and thread engagement, apply medium-strength threadlocker where vibration is a concern, and inspect fasteners after initial runs and periodically thereafter.
