P63 Spinner

Description

This is a 40mm diameter 3D-printed 4-blade spinner (cone and backplate) specifically designed for the 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 7×4 4-bladed propeller, NOT included. (Note: this specific propeller was produced for the 750mm Volantex RC Model P-51 Mustang: part# 768-1 please see the picture below).   FMS makes a 7×4.5 4-bladed propeller which will also be suitable.

Rabid Models doesn’t carry these props.  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 is a 24gm 1700KV brushless motor (which Rabid Models has available separately) 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!   If you desire, you can drill a small hole in the center of the cone to mount a cannon barrel!

Spinner Specifications:

White PETG.    Weight about 7.5 gms total (2 pcs).
The diameter at the base is 40mm (1.81 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.

This item is sold as a set (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.

This picture shows Steven Mathiasen’s completed Kingcobra model with added cannons!

Special note: some modelers may wish to use a 3-bladed prop – the P39 Airacobra used a 3-bladed prop and this model could easily be modified into a P39. It you’d like the 3-bladed version of this spinner please contact us.  The 3-blade spinner uses an 8×4.5 propeller (which we sell).

NOTE: Here is the construction article from the FEB 2022 Model Aviation magazine, including some pictures of the finished model with the spinner!
