The specific type of engine, whether it's glow, gas, or electric, is a key consideration for spinner compatibility.
Gas and glow engines:
Many 3-1/4 inch spinners are designed to work with gas and nitro glow fuel engines, and come with the required nuts and screws.
Electric motors:
A spinner for an electric motor often has a machined aluminum backplate with cooling slots to help with heat dissipation.
Propeller
Since this is a two-blade spinner, it is designed for a two-bladed propeller. If you are replacing a spinner, the new one must match the existing propeller's blade count.
Prop adapter
The spinner's backplate must fit onto the propeller adapter, which is connected to the motor's shaft. Many spinners come with multiple adapter rings to fit different shaft diameters.
A common configuration for a 3-1/4 inch spinner is an 8mm mounting hole, with optional plastic reducing adapters for smaller shaft diameters like 6mm, 5mm, 4mm, or 3mm.
An older gas or glow-powered RC plane may use a spinner that fits a specific threaded shaft size, such as 3/8 x 24.
