Gary:
That's exactly what I was thinking about yesterday. Nevertheless the space is still
very limited and I just don't know if it is worth the effort.
I do have access panels installed for the inner tanks and am able to check these
finger screens from time to time. I see the outer tanks as "auxiliary fuel tanks"
and don't intend to t/o or land while using them. Therefore it is also not
so critical.

I just look out the window (visual flap position indicator) and add a what
looks like about a 1/4 of the travel of the flap. If I want more to slow
the plane and/or increase the angle of descent, I lower the flaps some more,
each time taking a quick glance out the window.
Not to be flippant, but it is really that simple. I don't have a flap
indicator on the panel, and I don't think I'll ever want one.
Just or the record, I'm a 150 hour (or so) pilot with a tailwheel rating, so
I'm not terribly experienced. I've flown 152s, 172s, Cherokees, Super Cubs
and Huskys. All of them either have a flap position indicator or detents in
the manual flap actuator. My XL doesn't have either, and I even notice it.

My CH640 has an indicator because you cannot see the flaps from the cockpit. However,
I found it takes 5 seconds for full flap deployment, so 1 second on the
switch = 10 degrees which I find easier than looking down at the indicator. For
a normal pattern I use 10 at the end of downwind, another 10 on base, then
the rest on final based upon how steep my approach needs to be. I like to turn
base to final fairly high so I can always make the runway in the event of engine
failure. With 50 degrees of flaps you can come down pretty steep if you need
to.

| Subject: | 701 horiz stab question |
--> Zenith-List message posted by: Zed Smith <zsmith3rd@earthlink.net>
List,
Those who are already flying.......what is the consenus as to the mounting of the
horizontal stabilizer?
My ZAC manual indicates 135 mm from top of fuselage to top of flat-topped horiz
stab, with the top of stabilizer parallel to top of fuselage.
Looks okay to me. Four C-clamps in place. Nice and level, straight, plumb, flat,
balanced, centered, etc.
Before I drill it.....any advice? (Bolt holes are difficult to move)
Recent discussion leads me to think that an add-on tab would correct any nose-up
or -down problem at cruise.
Thanks,
Zed/701/R912/90+%/etc/do not archive

I'm getting ready to fit the baggage floor 7F5-7, but I don't see the
dimensions for the two cut-outs at the rear outside corners of the
panel. It's probably very obvious, but I can't find it.
Thanks for the help

The angle of the main wing affects the pitch attitude of the airplane. The angle
of the horizontal tail only affects the trim forces required to maintain level
flight, not the pitch attitude. If the angle is correct, you should be able
to use the trim tab to cancel out elevator forces from cruise speed down to slow
flight speeds. If it is a few degrees off, the plane will still fly but you
may have to hold pressure on the stick to mainrtain level flight.
On my plane, I couldn't trim out the elevator forces in level flight even with
full nose up trim. It flew just fine but I had to hold a little back pressure
on the stick all the time. I solved this problem after the third flight by lowering
the nose of the horizontal tail about half and inch by making and installing
a new set of front attachment brackets. Since each of these airplanes is
hand built and unique, you may find the need to make some minor adjustments. That
is what you will determine in your first few test flights.

Before I made that change, I flew the plane with a sheet of aluminum duct taped
to the bottom of the trim tab ,effectively doubling its size. I was able to trim
out the control forces on that flight using most of the available nose up
trim. Looking at the elevator deflection needed for level flight, I decided about
half an inch should be a good place to start. I still can't trim it out with
more than a few degrees of flaps but this is only a minor inconvenience during
final approach. It's on my list of things to look into when I have time.

I am think the same thing, There can to be a little problem with final rigging
(main wings angles or something) or Weight and Balance.
It will be advisable to go to this numbers one more time, better if one or
two experienced builders from your local Airport, Club or EAA Chapter (experience
in building any type of airplane or kit will be OK).
We do this everytime a plane is ready to fly when is finished from building or
was rebuild in our Club here.
Lots of little important details are not watched by the builder and can cause
problem.
The ZAC airplanes are very forgiving in flight, there are designed on the safety
side. Is something I like very much about Mr Chris Heintz and this ariplanes.
Probably will never give you any problem or scare you in flight as is now.
But if you can find this deviation and correct it. the plane probably will fly
better (less drag) and you will have a great peace of mind feeling when you
fly all over the world!
Welcome to Chapala, any time.
Here we are the two "Safety Advisors" for the list: Frank with vapor lock and
myself with Weight and Balance':-) :-) One thing is serious and important,
no one of us want bad news about any friend in this list.

Gordon,
Mine shows that the cutout starts 250mm from the front flange and 70mm
from the sides, with a 3mm radius. I can send a picture if you want.
