Larry,
I too am using the Becker Radio/TPX combo with the ACK-30 encoder in
my 701. Everything is now wired but I am told by my technical advisor I
have to take the plane to an authorized FAA station to have the encoder "
tuned " in the application and certified. Then every so often it has to be
re-certified for accuracy . Even though we have experimental A/C's and can
do the maintenance on them the encoder is one thing that has to be
calibrated and certified by a licensed technician.

Hi Perry,
I have just dismantled my Zodiac 601 TD and put it on the trailer for the
new owner to get it down to Canberra.
Just one word: Don't!
The average car transport trailers are to narrow, it is a major undertaking
to get the plane on the trailer, we needed fout people to CARRY it up, as
the ramps were to narrow.
One wheel was inside the trailer, the other one outside on the mudguard, one
wing under the plane and the second on the roof rack of the Landcruiser. It
hurt just to watch it, and I spent four hours just packing and strapping it
down. Even though it is sold I wouldn't want anything to happen to the
plane, and I gave myself the promise that no matter what I will not trailer
number two, exept for the first unavoidable trip to the airfield.
BTW, I have placed some pictures of my second Zodiac onto photoshare today,
any coments are welcome.
Cheers, Chris

Like anything else, this depends on the equipment. When I had a valve guide
fail 100 miles from home, I trailered it fine; but it took the right trailer
and preparation. The plane rolled easily up the ramp with proper adjustable
ramps. Using chocks and ratchet straps to the gear, it rode well all the
way. Of course I covered the wings very well to save my paint job and
prevent abrasion. This was, of course, a large trailer. 8 1/2 by 32 feet.

Hi Guys,
I am considering going for my IFR rating in order to increase the usefulness of
my certificate, and polish skills in general. Does anybody have comments regarding
the use of a 601hds as an IFR platform?
I didn't build the capability into mine originally, and was wondering if adding
the instruments might be worth it, as opposed to getting something like a 150
that's IFR certified.
Thanks!

What is required is that each and every transponder must be professionally certified
every two years by a firm registered to do this. I don't know which FAR
details it.
What I did before I knew that, was fly at 6,000 ft MSL per my digital altimeter
and ask SoCal Approach for a transponder check. They told me they had 6,010'
MSL once they gave me a squawk and I replied.

Has anyone considered tack welding some 1/4" round stock to the holddown leading
edge? This might be faster & more consistent than trying to file.
Just a thought,

Salut Michel,
This has come up before so I think there is some specific spec given by
Zenair mentioned in the archives somewhere (try to find it ha ha)...
As I recall 9 inches is about right. If you relate that to the length of the
slot in the firewall for the steering rods, you see the relationship of what
Zenair thinks is the absolute maximum travel for the nose gear and see how
that relates too.

Thanks to all who answered! I called Warp Drive

provide me with 9" of ground clearance.

Hi Gang,
I have exhausted my resources and have a question re my placement of my NACA scoop.
The air intake is for air input to the engine air box.
The scoop supplied with my Jabiru FWF kit is almost flat on it's mounting surface
and most scoops I have seen installed are put on almost flat surfaces. The
most convenient space I find on my lower cowling is directly under the centerline
of the motor and sloping up toward the prop. If I mount it here, I will
be placing it on a relatively curved surface and I am afraid it will allow some
air to directly impact the duct and pressurize the air thru the duct. Should
I mount the NACA scoop on the side of the cowl and use a flatter mounting
surface but longer scat hose to the air box, or a more direct route from the bottom
of the cowl with a curving installation of the scoop.
Thanks for you input

We mounted ours on the side of the cowl and that resulted in an almost
straight shot to the air box of about 8". I should note that our air box
was mounted so that the inlet side was at the bottom of the air box.

The 601 isn't any worse for IFR than a 150. I would pay the extra money for
modern equipment that is lighter. The 601 is a very light airplane. I
wouldn't want to fly it through any severe storms, but you won't be doing
any of that during training anyway. I'm slowly working to make mine IFR so
I can use it for currency.

I'm going to assume my encoder is reading correctly until the radar
guys tell me otherwise. When I get up and flying for the first time, will
call either Approach Control or Center for feedback on accuracy. Pour mans
approach, but I think it works. The key is to stay out of controlled
airspace until you get the verification.

Gentlemen,
I'm connecting wires between plugs that connect an ACK-30 encoder with a
Becker transponder and must ask if there are practical means for checking
out
the accuracy of the altitude reported. What have you with transponders
done in this regard or does one assume that the thing is suppose to work
directly
"out
of the box"?

I am building my 601XL in a 8 1/2 by 24 foot Haulmark cargo trailer. The
plane will not fit between the wheel wells of the trailer with the main gear
installed so I bolted a piece of 4" steel angle on the inside of the main
gear spring on each side with a 4" rubber tool box wheel bolted to the
bottom of each angle. I also had to remove the fiberglass tip fairings from
the horizontal stabilizer because the door wasn't quite wide enough. Now I
just roll it up the rear ramp and roll the nose wheel onto a 4" block to
allow the top of the rudder to clear the top of the door and chock it in
place and tie it down with ratchet straps. I don't have the wings in the
trailer right now but there's room on each side of the trailer for racks
fort the wings if needed. I would not recommend trailering the plane on a
routine basis, but it can be done.

Might also be better to mount it on the side where the propellor is
travelling downwards - i.e. the right side if your prop spins clockwise as
viewed from the cockpit. This should boost airpressure entering the duct
during conditions of high engine power/ low airspeed/ high angle of attack -
fwiw...?

I've moved my 601hds from home to the local airport and back twice now using
an auto-towing company with a flatbed truck. The driver is getting to be
well-trained as other pilots have used him too. The main thing I check is
that he doesn't use the hydraulic winch to put too much pull on the nose
gear. It makes me shudder to think how eaily this winch could rip the
aircraft apart! ;-(
The flatbed moves back and down at just enough angle to bring the aircraft
on/off with only a slight lifting on the tail at the critical moment to
prevent it dragging on the ground as it moves up/down the ramp.
My wings fit one-at-a-time in my mini-van, but if I used the roof rack, I
suppose I could do them both in one trip.
I have looked at the dimensions of a dual snow-mobile trailer (double wide)
and it would have a large enough platform. These trailers articulate to
provide a loading ramp - but maybe a bit steep for the Zodiac tail...? Again
the wings would be best carried separately.
The wing mounting / dismounting operation takes about an hour - or two -
without rushing. I've done it mainly alone but with another pair of hands to
help for a few minutes during the initial fitting or loading/unloading. A
good padded sawhorse comes in handy.
I conisder this to be an annual event - not a daily or weekly occurance.
Seeing as flying weather is pretty poor most winters around here, I've used
this time to continue the ongoing upgrading / building / repair process at
home in my garage. fwiw.

Here's a link:
http://www.tenryu.com/series.cfm?ID=15
You just have to check around at tool stores,
hardwares, home centers, etc. until you find a Tenryu
dealer, or click the dealer link on the link above.
When I entered my zip code, it didn't give me
anything, but when I put in the city & state of the
nearest city to me, it gave me the store I buy them
from.
Their are other blade makers who make this type of
blade, but I haven't found anyone making them as thin
as Tenryu. I tried others and got too rough of a cut
with no directional control once the cut was started.
