I also confirmed the 80 inch pounds with DA before I started using my 150. I have taken the bolts on and off a few times with no problems. In fact the first 3 times I flew it I was able to put a 1/8 turn on the bolts to get them back to 80. This is on a mej 32x10.

Huckin' it, is that whatcha call it? Had a lot of fun!! Yes, I was at the St. Helens field. Beautiful place but that tree is definately not ideally located. Thanks to all the members for letting me fly there, and to "Shakes" and Gary for inviting me out. Hope to do it again one of these days.

Grade 8 or close is good. They don't have to be AN specific. Just check the things after the first few flights on a new prop. You'll prolly have to set them again. Best is to also check them again before the next flight session, and do this everytime you go out. The "wobble" test works for between flights. Grab a blade and wiggle it to check for movement.

Wood props compress over time. Thrust action with the prop assures that eventually you'll have to replace a wood prop simply because the center has compressed too much. That takes quite awhile though.
