APC 20.5x13.5 Propeller Essentials

This APC AP205135EPN propeller is an electric pattern unit offered in a thin-hub configuration intended for precision RC pattern models. The 20.5x13.5 marking denotes diameter and pitch, while the thin hub reduces overall mounting bulk to suit compact spinner setups.

Fit this propeller when you want a stable aerodynamic feel for pattern manoeuvres. Before flying, confirm spinner or adapter compatibility, ensure the hub seats fully on your motor shaft or collet, and follow the motor manufacturer's tightening procedure to secure the propeller. Do not use this item on full-scale vehicles.

Tuning tips: balance the prop on a proper prop balancer, inspect for nicks or warps after any hard landings, and refine pitch and motor timing on the bench to dial in throttle response. The thin hub may need a thin backing washer or spacer to achieve correct spinner clearance.

Can I mount this directly on my electric motor shaft?

Yes. Slide the APC AP205135EPN fully onto the motor shaft or collet and confirm the hub seats evenly. Use the correct spinner backplate or adapter and tighten according to the motor/collet instructions to prevent slippage.

Do I need a spacer or special spinner for the thin hub?

Often a thin backing washer or a shallow spinner backplate is required to set proper propeller clearance when using a thin hub. Check spinner fit on the bench and add a spacer if the blades sit too close to the spinner face.

How should I verify safe installation before flight?

After mounting, hand-spin the propeller to confirm no rubbing, then run a low-power motor spin to check balance and secure fastening. Inspect the hub seating and spinner clearance under full control throws before the first flight.
