Hey Jon,
You're not missing anything, there is no "axle retaining" mechanism shown in
the plans. This, however, should definitely be added.
As mentioned, most people use a cable look, BUT if you go that route, be
sure to make it sturdy and use a few nico sleeves if you use nicropress
sleeves. I personally know someone who's bungee's failed on one side and
the "backup" cable slipped through the sleeve. Busted prop and an upside
down airplane resulted.
I made a "U" of thin aircraft tubing, flattened both ends and affixed it to
some of the AN3 bolts holding the lower "V" brackets together. Can't say
how it'll work, but should be sturdy.

Rick/Douwe, thanks for the help. Just wanted to make sure I wasn't overlooking
something in the plans. This looks like one of those areas where it might be fun
to get a little creative with engineering. Rick, in the photo you posted, I'm
guessing the downfacing rod is both a guide pin, and to keep axle from rotating
with brakes. I might try to come up with something that is both a safety
cage and rotational stop. If I get some time I will have to look at ideas on West
Coast Piet.

Jon,
Your are right, the down tube is an anti-rotation device since this set
up has brakes. The photo I sent is not of my plane, though my set up is
the same, but of Mike Cuys. A little more elegant way to set up the
"safety strap" in case of bungee failure, is a modification of the loop
seen on Mike Cuys plane. This is similar to what Dowe spoke of, but
still uses a cable.
The photo is a nice example on Dan Helspers plane. I just used a loop,
but that was done an hour before first flight last year. I will do what
Dan has done using 1/8" or 5/32" 1x19 cable as soon as I can. I am sure
it will be strong enough.
Regards,
Rick Schreiber
