[450] Slack Loop Addendun

[David McKenzie]

Notice the spacing distance on the mast, because it is only 10 feet tall
there is no way to stack ideally and use the thrust bearing, so you have to
take a little off where you can. I would seriously recommend doing it this
way over just sticking the beam at the top of the rotor as it is now unless
you want to wake up to disaster. You'll notice that it looks much more
sturdy (because it is), and it also doesn't add anything noticeable from the
ground. That way when the owner finally does bother you, you can tell him
how sturdy it is to belay his fears.
