A propeller hub to suit the DLE 111 twin — a large two-stroke petrol engine for big 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.
