The problem I've had in the past, many many years ago was my wooded prop if the hit a tuff of bluegrass or what ever they'd break, so I always ran plastic.But that was on zenoah's, quadras an sachs.
Yes I had a few prop strikes but those engines could take it.
I don't know about the DLE's though, I've heard of bending cranks and all that.
Yup, me too! Grass fields, especially the one I fly from, are not very wood prop friendly. I have a couple of gallons through a SYSSA, and even more through a 26cc RCGF and Quadra42, and at least 6-8 broken APC's between them. Maybe more(?). Just the one bent prop bolt to show for "plastic" prop damage. I flew MA for a while (love the scale appearance!), but started running into difficulty balancing them, especially the 18" and larger ones. Tried APC, and didn't have the balancing problem. Very good durability, and I think, performance.
