Zip ties, the great Satan
 

Just a note. I haven't seen a Skymaster without these so, maybe you will want to do a quick check.

DO NOT put zip ties on your rear motor mount. I know it's tempting, but don't.

If you do have them on. Just slide them a little up or down and check UNDERNEATH them to see how much of your mount they've eaten. I think some of you will be surprised at what you find.

Just a thought.

also be sure to check the clamps that hold the prop bottle on they were metal to metal
