I wonder about durability

Was discused already here.

Good point. My prop still looks like factory so I’d like to say I have good habits there. Hopefully the material has some flex to makeup for its girth.
Going to order one for a winter project/test.
@Paige oops, did not see it. Big enough improvement to warrant a thread, I’ll flip back to this someday when I put it on.
Do I care which one?
Thanks guys. I ordered a 10x5 for my 40lb thrust. $6 plus $4 mailing? Rather inexpensive.

The 10x4 seems like a better pitch for a 30lb thrust but beware that the shear pin does not have a locking housing. The 10x5 has a locking housing. I’d say a 10x5 for 30lb+ thrust motors and maybe a x4 pitch for 30s, but the risk of no locking shear pin mold might be worth it for a x5 even on a 30.
The gains are more noticeable on 30lb+ motors.

I have the 42lb thrust and will go with a 10x5.

Got my new airplane prop and took off my existing factory one... doh!
Have a problem. The slot that the shear pin fits into is not the same size. The new prop's slot is just a little too small.
Did i get the wrong prop? Should I try carving out the new prop a smidge?
BTW, I must of hit a rock sometime cuz my shear pin is ever so slightly bent and the prop slot shows a small break.

Mine was pretty tight as well you will also need to add another flat washer under the nut...
Were you casting towards your motor?
That's how I get a steady retrieve
