40mm 4-blade Spinner for the Fun Scale Models P-63 Kingcobra

The 40mm diameter 3D-printed 4-blade spinner (cone and backplate) was designed specifically for Derek Micko's 30" wingspan "Fun Scale Models" P63 Kingcobra model, as shown in the February 2022 issue of Model Aviation magazine.

This spinner is designed to be used with a 7x4 4-bladed propeller, NOT included. Sorry, Rabid Models doesn't carry this one.  However, its available for the 750mm Volantex RC Model P-51 Mustang: part# 768-1 - please see the picture below) and FMS makes a 7x4.5 4-bladed propeller which will also be suitable.  NOTE: we also offer the same spinner in a 3-blade version, for the P-39 Airacobra. That spinner uses a 9x7 3-blade propeller (which we sell).

 If you desire, you can drill a small hole in the center of the P-63 spinner cone to mount a simulated cannon barrel! The P-39 version has the "cannon hole". 

The spinner is for use ONLY with electric motors and propellers.  In addition to the propeller you will need a prop adapter to mount the spinner and prop on your motor shaft (we do have the prop adapter). The recommended motor for the FSM P-63 is a 24gm 1700KV brushless motor (see the "power packs" section of the catalog) and a 2-cell battery. Once the backplate is installed on your motor shaft with a prop adapter, the spinner cone simply snaps on - no additional hardware is needed! 

Spinner Specifications:

• White PETG. Weight about 7.5 gms total (2 pcs)
• The overall height is about 38mm (1.5 inches
• The diameter at the base is 40mm (1.57 inches)

The spinner backplate has a centering hole which needs to be drilled out to fit your prop adapter. You may also need to drill out the center of your propeller to use the prop adapter. Some props may require the prop cutouts in the spinner to be slightly enlarged.  Here's a video from Fun Scale Models which shows how to finish and install these spinners.

The spinner is sold as a set of 2 pieces - one Cone and one Backplate. The plastic parts are unfinished - but they can be sanded smooth and painted with any plastic-compatible paint. Painting is recommended because all plastics will deteriorate over time if exposed to sunlight.
