APC AP07038WSF 7x3.8 WSF Prop - Wide Blade Slow-Fly Upgrade  [AP07038WSF]

Wide-Blade Slow-Flying Propeller

The APC AP07038WSF is supplied as an aftermarket replacement prop for electric slow-flyers. The 7x3.8 dimensions and WSF wide-blade shape are chosen to prioritise low-speed lift and steady handling, not to indicate a specific aircraft fitment.

Fitting is straightforward: remove your existing prop or adapter, slide the APC onto the motor shaft or adapter, verify rotation direction, and tighten using the original nut or retainer. Ensure concentric seating on the shaft and confirm there is no contact with the spinner or fuselage before powering up.

Performance notes: expect improved static thrust and calmer behaviour at low RPMs in exchange for a lower top end. This prop is ideal for scale presentations, beginner training flights, and any model where slow-speed control is more important than maximum velocity. Balance the prop before the first flight and monitor temperatures during initial runs.

Upkeep tips: inspect blades after hard landings for cracks, chips, or delamination; rebalance after swapping spinners or hubs; and replace the prop if any structural damage is found. Regularly check mounting hardware as part of your pre-flight checks.
