Hi all,
Any opinions on a good cover for the 701 cockpit? Been wanting to get one for overnight/extended
trips. It would be great if it wasn't very bulky when packed
up. Have thought about hacking up a car cover and making my own. Are any available
for sale anywhere?
Thanks,

Members,
I have seen several posts concerning what speed to expect in cruise
depending on which engine is installed in the ZodiacXL. I guess one can
use anything from a 75 HP VW to the 120 HP 0-235 and get better climb
and cruise performance depending on the prop as well as the engine. I
have a 120 HP Jabiru 3300 installed in my ZodiacXL. My top speed with
the engine running wide open in cruise is 135 MPH. I reduce engine
speed to 2500 RPM on a trip and cruise at 120. This is with a washed
clean airplane with wheel pants. I have no idea weather the wheel pants
or wash job increase speed performance but have heard both help.
The above is fact now here is my opinion. If you would be
satisfied with Cessna 150 performance in your ZodiacXL, then install a
75 HP VW. If money in no object use the Lycoming 0-235. I think that
any engine that will produce at least 100 HP is suitable for the
ZodiacXL. I used the Jabiru 3300 which is rated at 120 HP. The cost
was about $14,000.00 and the firewall forward kit was another $495.00.
I am very satisfied with the performance of my aircraft both in climb
and cruise.

I've tried the suction cup mounted sunshades in my plane, the little
square ones about 18" square. They kept falling off because the
suction cups wouldn't hold. I seriously doubt any suction cups would
hold the Koger sunshades in place for long.
If you thoroughly clean the surfaces before applying and carefully
bend the aluminum rail to match the curve of the canopy, the 3M
double sided tape should hold the sunshade in place with no trouble.
I've seen no signs of mine coming loose so far.
As far as being removable is concerned, the Koger sunshade can be
easily removed, leaving just the narrow aluminum center frame behind.

Bryan,
You are right about the suction cup shades coming off. I have the
RV-7 shade installed in my ZodiacXL and it does not cover the last part
of the canopy so I use two of the black 18 inch square suction cup
shades and the right one seems to be holding very well but the left one
is always falling off. As for the Koger center rail, it glues on after
being bent to match the conture of the canopy and I don't think you
could pull it off without destroying the canopy. My dad sent Ralph
Koger an e-mail some time ago with a drawing of a shade with dimensions
suitable for the ZodiacXL so he should have shades that will fit by now.

| Subject: | Re: 601XL rear spar risk mitigation |
Another thing to emphasize would be to "polish" the hole edges as well. Since the
necked down area of concern near the flange in the original spar is now occluded
by the strap doubler, it could crack without being detected. perhaps add
a strip of this along the lower edge after polishing to avoid notching or dinging
during asembly?

I appreciate all the feedback I have gotten on my idea to mitigate the risk of
rear spar failures by adding a small strap to the lower spar flange in the area
of the aileron pushrod hole. This was discussed in detail at
http://members.cox.net/n601ge/drawings/rearspar.html
Many people have other ideas, which is why it's called "experimental" aviation!
I would like to add some notes:
[1] It should be straightforward to inspect the strap doubler on a regular basis
for working rivets or cracks. So an additional good characteristic of this
type of risk mitigation is that you can use it to get some real data on the
hypothetical problem. If people install the strap and report no damage over time
(50 hour intervals?), then either there was no problem there or the minimalist
fix worked like a charm. If people later report that they are finding evidence
of strap fatigue, then we have identified a "real" problem and can work
out a "real" fix.
[1a] If you install such a strap, you should note it in your builder's log and
consider putting an inspection item in your annual checklist - "Visually inspect
strap doublers on rear spar lower flange in area of aileron pushrod for any
evidence of cracks, fatigue or working rivets." Over the years, as evidence
builds, you will gain (or lose) confidence in the design and/or strap.
[3] It was brought up to me by one respondent that for scratch builders, there
is an option to use a 2-piece rear spar, and that this design has a larger,
heavy-duty splice in the same area. If people with that design built and flying
can inspect the doubler and report its apparent condition, those would be additional
data points.

I have seen this done. Find 1/8" wide masking tape for doing the complex shapes.
OR use 3/4" tape over the joint, mark the tape, cut with an exatco knife and lift
the side you don't want.
Just some thoughts,

Hi,
Just went to buy Mobil 1 MX4T motorcycle oil for the Rotax 912S, which was on the approved list, and found that it's been renamed to "Mobil 1 Racing 4T". Just thought I'd post in case anyone was unsure this is still the same oil. From www.mobil1.com:
"Mobil 1 MX4T 10W-40 was renamed because the product is known as Mobil 1 Racing
4T 10W-40 outside the US. Mobil 1 Racing 4T 10W-40 joins Mobil 1 Racing 2T, for
two-cycle engines, and Mobil 1 V-Twin 20W-50. Be assured that no changes to
the Mobil 1 MX4T 10W-40 formulation occurred during this name change. Same great
product, new name. "

As far as VG's are concerned if there percieved benifits are repeated enough

Subject: Zenith-List: 701 slats
In a recent post a fellow "poster" used the "I have heard" statement to
compare performances between aircraft with equal HP engines performing about
the same. This is what he said;
"There is a savana in Nth Qld with the VGs and VG wing mod with 80HP
Rotax and From what I have heard the cruise speed is no better than my CH
701 with 80 hp Rotax 70 knots 5200rpm 2 up. if you want an
improvement in speed use 100hp Rotax cruise 80 Knots".
There is nothing wrong with the post other than it has minimum validity to
it. Except the more hp part. A person can say "I have heard" about
anything. The only problem is that if it repeated enough, it becomes fact.
There are only a few ways a true comparison like that can be made. One is if
all the variables are the same and it becomes a true apples to apples
comparison and another is if enough runs are made by both to compute some
types of averages or I guess they could race. But, "I have heard", nope I
don't buy that one. You will have to pardon me, it's just a pet peeve with
me. However, I have heard, less drag, more lift equals better performance.
That's just a rumor, don't repeat it. lol.
Just funning, don't get upset.

It's been awhile, as a mater of fact last November 2006, during CC 10
that I talked to Mark about doing my heads. He told me to just scrape
off the rough stuff and ship em. Told me then I was number 10 in the
Q. I told him I was in no hurry but wanted him to do his magic to these
95hp heads which had some broken bolts and bad exhaust pipes etc. All
this took place over the phone, I have never met Mark face to face.
This week the heads arrived and they were in two boxes and packed very
well. I opened them up and took some pictures to show you guys just
what kind of work this guy does. I must say I am very pleased with the
results.
I don't please all that easy. A little of my history, 10 years as a
machinist in the Chevrolet Engineering Center / Powertrain Engineering

doing excellent work. Recommended!
