I build brake lines.
Any builder (with any luck one near by) who is in need of Teflon core stainless
steel braided brake lines please contact me.
I would (ideally) would like to find a builder near that I can "mock up", but
regardless the builder who is willing to work with me (that is the builder of
each model Zodiac XL, CH 701 and CH 801) will only pay the shipping costs for
the brake lines as we are developing them for each build. When done the lines
will be yours.
Your current brake configuration should be stock (plans built).
I hope to hear from some builders soon, but if not well the best of all to you
and good luck with your builds.

Guys,
Make the leading edge skins oversize before you bend them. We were unable
to bend them on the bend line even though we had the pipe screwed to the ta
ble when we bent them. They were off just enough that they wouldn't work,
so add 20 or 30 mm to top and bottom (40 to 60 mm total to the skin width)
and trim later.
Dave

My error, I see that I failed to (in my first post) to state that.
The city is Upland, the state is So. California (5min from CCB airport).
If there are builders within...say 1-1/2 hour drive I would be willing to meet
any builders who may be interested.
Thank you for taking the time to view this posting and responding.

I read William's article on the topic of 601xl safety and recommend it to everyone.
Hopefully it might help cut down on some of the wild speculation that to
my eyes can sometimes seem so breathless that I wonder whether there may be mischief
behind it. I was particularly taken by his reminder about the Audi throttle
"problems" and how SUV's are only inherently more dangerous than other
vehicles if you ignore differences in their center of gravity etc.
I am in the camp that says I pretty much follow Zenith on all questions related
to the airframe, and William on all questions related to the engine and firewall
forward. If there is serious question concerning their advice, then I consider
it, but it certainly requires better credentials than those of people like
me and most of us.
Hence William's tendency to remind us of his background and credentials. Thus,
I was irritated by the snarky and childish comment from a few days ago that he
is "puffed up". He has no axe to grind and devoted some time to a well thought
out article. Let's just focus on the substance. Now I'm going back to finishing
my plane so I can fly it

Boys & Girls,
I've looked through the archives, and found only
a little on this, though I think I remember previous discussion. Given
the stroke of the flap motor (Feb. 2006 kit), I can only achieve 20
to 22 degrees travel with the linkage in it's most geometrically
optimized position. I could gain maybe 2 degrees more by drilling a new
(lower) hole in the torque tube arms. So ---- Is this sufficient for
all purposes, including perhaps a steep approach for an off airport
landing? Have others had the same outcome? Comments please.

I don't know about how much travel is needed. But if you have the old
factory actuator with the exposed and adjustable limit switches, wouldn't it
be easier to move one of the limits switches instead of drilling a new hole?

dont redrill or redo. the flaps are more than adequate at 20 degrees. just make
sure they are even and lock in place in the up position.

Lynn,
I've had a problem with flap travel, also. Part of my problem is total flap deflection.
I talked with Caleb at ZAC, and he told me that the recommended deflection
had been reduced from 30 deg. to 20 degrees. I can get 20 degrees.
My other problem is that with the travel I have, I can't get the limit switches
close enough together to be able to trip both of them with the traveling "donut"
on the actuator spiral. I have temporarily set the "down" limit and will eyeball
the up position of the flaps.
Long term, I am going to add an extension to the bellcrank arm. It will be a one
inch extension at an angle of 30 degrees up from the centerline of the bellcrank
arm. I think that will give me the travel I need to get adequate separation
of the limit switches.

Hi Lynn,
My flaps go around 30 degrees. I have the older flap motor, while
you have the newer one.
I don't know how the difference plays into performance. My plane
hasn't flown yet. I suspect 10 or 20 degrees of flaps is all that
would be helpful for short takeoff, and for landing you can always
use a forward slip instead of (or along with?) flaps to produce a
steep glide angle.
Have fun,
Paul

Craig,
What I'm saying is there is not enough stroke in the flap
motor mechanism. The limit swiches are not a factor in this. Even if
there were more travel available, the rear frame channell (6B5-2) would
be in the way, and prevent much further travel downward.

factory actuator with the exposed and adjustable limit switches,
wouldn't it be easier to move one of the limits switches instead of
drilling a new hole?
