Gerry, I know that the Zinger is probably not the best choice in props, but for my first shot at this I didn't wan't to screw up a $50+ prop. DA reccomends a 22x8 for breakin, so I thought I go with those numbers to start. No one has really addressed my initial question, though, regarging the orientation of the holes in the prop hub.. Some say it doesn't matter, but I have a hard time believing that. Others didn't read or understand my post fully. The DA50 has a 4 bolt prop not a 6. What are your thoughts on the orientation of the 4 bolt holes?
Happy flying,
Paul

New to gas here. I'm ready to drill the mounting holes in my prop, but don't know how the holes should be oriented to the prop hub. If the prop tips are at 3 and 9 o'clock, are the holes drilled at 12, 3, 6, and 9 o'clock or are they drilled at 1:30, 4:30, 7:30 and 10:30? I've got to think that that there's a right and wrong way to do this. I've got a drill guide, but no instructions on how to use it. What do you guys do?
Engine = DA50
Prop = Wood Zinger 22x8
Thanks to all in advance

No one yet has commented on your prop. I think most would agree that Zinger props make good paint stirrers but should not be used as airscrews if at all avoidable. There are, however, many good wood props out there, 3W, Menz, Bolly, DA etc. I would also suggest that eventually you will be much happier with a 22x10 on this engine. The 22x8 will seem to leave the model stuck in first gear.
