APC AP04055E-B4 4x5.5E FPV Prop Set — 2 Standard, 2 Reverse  [AP04055E-B4]

4x5.5E Prop Set for FPV Frames

The APC AP04055E-B4 bundle supplies a matched set of 4x5.5E props for small-frame FPV and freestyle quads. Both rotation directions are included so you can assemble the correct counter-rotating pairs that many frames require.

This kit comprises two standard and two reverse rotation blades intended as replacement or spare props for practice and events. Having a spare set helps shorten turnaround after a crash and supports consistent flight sessions.

Fit each prop to the motor with the corresponding rotation direction, verify the prop adapter or nut mating is correct, and check that the blade leading edges and faces sit as intended. Remove and replace any prop with chips or deformation to avoid vibration or loss of control.

Compatibility notes: confirm your motor shaft and prop mounting style match the APC AP04055E-B4 design before purchase. Proper mounting and routine inspection keep handling predictable and reduce wear on bearings.
