This 38mm spinner was created as an RC finishing piece to fit motors with a D3.0mm shaft, giving a neat nose contour for electric propeller installations. The translucent orange surface improves visibility for pre-flight inspection and identification on the model.
Check shaft diameter carefully: the spinner is centred on the D3.0mm dimension, so confirm any shaft shoulders or flats before mounting. It is intended as a cosmetic and trimming accessory and is useful when balancing props and refining nose weight for flight behavior.
Mounting advice: ensure the spinner slides onto the D3.0mm shaft without interference and that it clears nearby cowlings or mounts. Use standard spinner mounting steps for your airframe and re-check dynamic balance after adding propellers or adapters.
