Hamilton Standard NP 2000 8 blade composite propeller 1/48 scale used on E2 Hawkeyes and some C-130's. After using 4 of these on a C-130, I have modified the model to correct an issue. The hub behind the blades is now straight & matches the measured size of the engine nacelle (Hasegawa & MPC C-130E). Also the hole goes all the way through. Note: These are NOT the 6 bladed props which require the C-130J's longer nacelles. These are 8 bladed props made by Hamilton Sundstrand & are a OEM retrofit to the older style E & H engine nacelles. I had very good results with the white strong & flexible plastic. NOTE: the description of my experience applies to the 1/72 model.
