A propeller hub to suit the DLE 20RA single — a small-displacement two-stroke petrol engine for sport-scale models.
On this engine the component is the propeller hub, which mounts the propeller to the crankshaft and transmits drive to it.
Why this part matters: the hub takes the full propeller load and any prop-strike shock, so cracks or a worn bore are a structural failure risk.
Fitting note: Inspect closely for cracks after any prop contact and check the taper and key for fretting.
