WLtoys K170 Main Frame Set - Original Internal Chassis for UH-60L

Restore Structural Integrity and Component Alignment

A cracked or warped internal frame is often the hidden cause of gear stripping and persistent flight trim issues. This WLtoys K170 Main Frame set solves the problem of a compromised "skeleton" after a hard crash. By providing a rigid and perfectly square platform for your motor, servos, and main shaft, it ensures that all mechanical parts work in harmony without the flexing that leads to premature wear. Ships worldwide.

Install Tips

• Complete Swap: Replacing the frame requires a full teardown; take photos of your wiring routes before starting to ensure everything goes back in the same place.

• Screw Management: Do not overtighten the screws into the plastic frame; snug is enough. Use the original factory screws to ensure the thread pitch matches perfectly.

• Bearing Seating: Ensure the main shaft bearings are pressed completely flat into the frame seats before sliding the shaft through to prevent binding.
