Frequently Asked Questions
Where does this hatch mount on the plane?
This is the fuselage-top battery hatch cover for the FMS 1300mm PA-18 Super Cub, covering the battery bay opening on the upper fuselage for easy battery access and swap between flights.
How is the hatch retained — magnetic or latch?
The PA-18 1300mm battery hatch uses a magnetic retention design for tool-free, quick-release battery access. Simply lift the hatch to open and press down to close — no latches or screws required for normal operation.
Can this be used on other FMS planes?
Not recommended. The hatch shape, dimensions, and magnetic mounting points are designed specifically for the FMS 1300mm PA-18 fuselage and are not compatible with other FMS models.
I lost the original hatch. Will this fit perfectly?
Yes. This is a factory OEM replacement part with identical dimensions and magnetic mounting to the original hatch. It is a direct drop-in fit with no modification required.
What if the hatch becomes loose or doesn't stay closed?
Check if the magnetic retention points have weakened or if the hatch seating surface is warped. Applying thin foam tape along the hatch perimeter can improve grip. If the magnets have lost strength, replacing the magnetic pads or the hatch itself is recommended.

Description
Keep your battery bay protected and your pre-flight routine efficient with this official OEM replacement battery hatch cover for the FMS 1300mm PA-18 Super Cub. The battery hatch sits on the upper fuselage, covering the battery bay opening and securing the battery during flight. It uses a magnetic retention design for tool-free, quick-release access — lift to open, press to close, no latches or screws required.
A cracked, warped, or lost battery hatch should be replaced before flight to prevent the battery from shifting or ejecting during maneuvers. This factory-spec replacement is a direct drop-in fit with identical dimensions and magnetic mounting to the original.

Compatibility:
- FMS 1300mm PA-18 Super Cub — upper fuselage battery bay hatch
⚠️ Important: This hatch is designed for the FMS 1300mm PA-18 only — not compatible with other FMS models. Always verify the hatch closes securely and the battery is firmly seated before each flight. If the magnetic retention feels weak, replace the hatch before flying to prevent battery ejection.
Installation:
- Remove any remnants of the old hatch from the fuselage battery bay opening.
- Align the new hatch over the battery bay, ensuring the magnetic contact points line up with the fuselage magnets.
- Press the hatch firmly into place and verify it closes flush with the fuselage surface.
- Open and close the hatch several times to confirm smooth magnetic retention before flight.
