I changed the prop on my nexstar and it seems to always come loose. I have used loctite....

I do have a question about the installation........ Is the prop suppose to touch the nipples/marks on the spinner backplate? Maybe I have it installed incorrectly...... So when you are looking at the prop from the front of the plane, the nipples will be touching the prop on the right side???? I wish I had a pic and the picture in the manual isn't the best.

Thanks
