You don't have to drill a hole in your prop to fit it.

I forgot to say, If I tighten them anymore the screws start to shred

Is your motor shaft 4mm? However use threadlock on the screws to keep them in place.

 oliver 17 points

yes the shaft is 4mm. I was looking at it and it seems like the screws are slipping on the threads of the shaft and sliding up to the top, is that what would normally happen if the screws where loose?

You should have 10 prop savers (Prop Saver w/ Band 4mm (10pcs)) so try to find the best one.

You have to drive down the shaft. Sand a bit so that the screw does not slip

Shafts designed for prop-savers will have come with a flattened area. If you have a round shaft it was probably designed for a collet adapter instead. If you want to put a prop-saver on it, you need to use a rotary tool with a grinding bit to flatten the parts of the shaft where the screws will grip it. That will make it impossible for the prop saver to slip off. If you don't flatten the shaft, you can tighten the screws until they strip but they will still slip off unless you glue the whole thing in place with threadlock.

First slide the metal ring with screws over the shaft and tighten down the screws on the shaft. Then slide your propeller over the beveled part of the ring. Put one side of the o-ring over one screw, stretch over the propeller, and attach to the other screw. Beware though, that these o-rings aren't really made for this and they give people some issues by braking off and letting go of the prop. (You can use the pulling glider bungee to secure the prop if you are extremely worried. This should do

Drugos, can you post the pictures again?

Just search google images for prop saver and you will see plenty of photos of how to install them. One thing I like to do is install two O-rings because I fly a quadcopter. O-ring is just thick rubber band and it will eventually rot and break, resulting in crash. If you have two O-rings, if one breaks the other will hold the prop in place. I came back yesterday from successful flying (no crashes!) and noticed an O-ring was missing... so it pays off to put that second O-ring!

They aren't very long.But you can replace them with longer ones.
