Silversurfer, I agree with your post. Once I drilled it, it's mine. Even though the guy I talked to said to do the same thing I did...wrap the drill jig with tape until it fit snug in the prop hole. The really wierd part is I drilled the 4 holes without ever touching the jig, but when I line the holes up to the da50 prop washer, two holes will line up but the other two arern't. Either way I look at it, the prop is no good, I didn't know some of the centering holes had different sizes. I wanted to get it on the plane pretty quick so I could get it in the air. Oh well, I'll call 'em up and get another one on the way.
