RE: OS 46AX On A Header & Pipe
Appearances could be deceiving...
I know the specs do say the hole in the prop is drilled to 8 mm, but from measuring the dimensions in the photo, it seems to differ...
If the hole is indeed 8 mm, the hub is HUGE at ~34 mm in diameter.
For reference, I took a shot of a used Master Airscrew 11x6 Series-2 black prop, drilled to 7 mm, with my vernier caliper open to 34 mm around it.
Its hub diameter is just 24 mm.
See below.
I know an APC has a larger diameter hub, but the Graupner G-Sonic does not seem to be any larger than it is; and the APC hub measures up to only 1" (25.4 mm), according to the Tower Hobbies photo.
Can anyone verify that the actual diameter of the drilled-through hole, in the G-Sonic 11x6 is really 8 mm?
Photo analysis does not make it appear so.
