George, I dont have any pump on mine. Because the 2200 has the carb down low there
is enough head for the specified 0.75 psi ? requirement and I did fuel flow
checks including tail down measured flow into the carb float chamber was all
above requirements.
This meant I could remove the engine pump and eliminate another source of trouble.
A rotax would be different because the carbs are up high

This is probably a Rookie question and is only for discussion as I have access
to three scales, but if one wanted, could you correctly weigh an airplane
with just one scale if you put scale height blocks under the other wheels as
you moved the scale from wheel to wheel? First glance is that it would weigh
correctly as long as the other wheels are at the constant height. Not very convenient
though.

Question
I have a Ch701 a friend of mine is building a ch601 HD which has been un
touched for a number of years .
He hopes to soon be building again.
I mentioned the solid alloy gear legs .
Can he build his fuse to take the alloy legs ( the fuselage is not
started )
he intends to build a tail dragger and has the wing mount wheel kit.
Thanks Graeme

No, I am still fighting the vibration problem. Just got my prop back
from Culver. They said it was way out of balance. Hopeful we will spin
it up any day now. The weather isn't cooperating.
I always have to have something to do. I'm retired and if I sit on my
rear end I would probably not have to worry about projects long, if you
get my meaning. Plus I picked the kit up pretty reasonably. So why
not. Larry

Larry, if you have taken on a new 701 that must mean that your Skyhawg
is flying. I must have missed the announcement, I try to watch this list
closely, but from time to time I just get to busy. Especially with
Arlington, Oshkosh , UPAC convention and building a 601QBK for a
customer, I have hardly had time to watch this list for recient events.
So how is the Harley working on your plane? Do you have some #=92s to
share yet? I am curious on how you like those Pegastol wings now that
your in the air and have tried them out on a 701, can you report on
their value with actual data now, or is it still too early in the
testing phase?
You have put a lot of time into your 701, I have been watching your
progress ever since you had the Sub 2.5 L in it. Congrats on completion
and the fortitude to start another project so soon. It lends a lot of
credibility to a builder working on their second plane while flying
their first plane.

I needed a new project so I just bought a part of an unfinished 701
kit consisting of the tail and wings. I am going to build the entire
plane strictly for sale upon completion. I will need a few things, like
fuselage parts, instruments, engine, prop, landing gear, etc. Any of
you know of any bargains, e-mail me @ lrm@skyhawg.com.
This is going to be a plain Jane quality build. Nothing fancy, except
it will definitely have sliding seats. I have no idea of what I am
going to ask, but it will be reasonable. So if any one thinks they
might be interested in about 6 or 7 months, e-mail me and I will put you
on the list. When it's done and ready for the DAR I will contact
everyone on the list. I plan on being done in the spring.
I will also start a new section on my site about the progress of this
new project. Check it at your convenience and thank you.

Dan,
The vents you mention are still needed because the battery has a limited
life and will require replacement. The next person replacing the battery
may not choose the gel type on the next go round and problems with not
having vents may become an issue.
In any case, I'd not hesitate to put in correct vents.

I'm sure that a single scale (or two to average out) would be adequate. Sure,
it takes a little longer. But how often are you going to do it? I would like
to know if a 300 pound scale would be enough? What are the empty weights that
builders are seeing on the MLG? The nose wheel? The price of scales go up for
a 400 pound scale. Those analog spring scales may be inaccurate near their
upper limits. I am going digital for the accuracy. I will try to borrow or rent
because I'm cheap. Medical scales go up to 800 pounds. Alternatively: I weighed
the tongue weight of my RV trailer using the mfg.'s published method. Bridge
a solid fixed point and the scale with a 2 by 6 plank. Put the tongue on the
plank at a 2/3 point. I doubled the reading and I found that the tongue weighed
MORE OR LESS 700 pounds. I used a 300 pound bathroom scale. That's a whole
lot of trouble for three wheels though.

I am on schedule with setting up the shop and ordering materials to
begin scratch building a 701 first week of September. In the
meantime I have read and heard about handling problems at low
approach speeds. The announcement yesterday from Stol Speed re
putting VGs on the elevator (together with removing the slats and
VGs on the wing) achieving excellent results brought the issue up
again. I am tempted to order the VGs today. Here is the question--
how do you all feel about eliminating the slats and adding the VGs.
Thanks, Jerry

Not for a homebuilt, any scale will do as long as you can get a fairly

I would use two 300 lb scales in tandem. That way you can keep the
readings near midscale where it's more accurate and you don't have to
worry about overloading the scales. Just put a plank between the two
scales with the tire on the plank and add the two readings. Calibrate
them first with known weights.

Bryan,
My weight empty with oil and coolant is 265, 264 mains and 231 for the nose.
I found my 300 lb scales are accurate +/-1 lb so long as you place a 1/4
inch aluminum plate under each tire for weight distribution.

I seem to remember when studying for the A&P test that
the plate should be greased so as the weight was
placed on the scale that it would slide and relieve
any sideways stress. That was a long time ago and in
a galazy far far away.

Am I the only one to catch my math error on my "alternative method?" Double
it if the weight is center plank. Seriously, its a clunky way to do the deed,
but its still my fall back method. I will be looking for at least a 330 lb
digital scale. My ball park figures for a plane not yet completed are based on
some numbers from completed Lyc 601XL's. And that is north of 800 lbs empty
weight. I hope I'm pleasantly surprised. I'm just guessing that the weight on the
mains would be at least 650. Another thing. Not to offend, but I'm converting
MM's to inches and do the chart C in Yankee inch/pound moments. I've been doing
W/B in that format for half a century and I'm too old and ornery to change. I
can build in metric but flying is another thing. When I was working for the
man, I had been handed many manifests in kilos and even Stones. No problem.
Furthermore, I've given some thought to moving the datum to the prop hub so that
I don't have to compute with negative numbers. It does say "experimental" on
the airplane after all. This will conform with most every thing I've flown in
the past 40 years. Except for my 46 Luscombe and anything else certified before
there was an FAA.

Bob:
There is nothing experimental about moving the datum to any convenient
point. At Boeing, as I remember, the zero datum is commonly placed
ahead of the nose. so there can be no negative moments. (Well, I admit
to a few negative moments while I was at Boeing, but that's another
matter.) It was also common to use a "constant moment" diagram to
simplify weight and balance calculations. Have you used that sort of
W/B presentation?

Subject: Zenith-List: Re:weight & balance with one scale?
Am I the only one to catch my math error on my "alternative method?"
Double it if the weight is center plank. Seriously, its a clunky way to
do the deed, but its still my fall back method. I will be looking for at
least a 330 lb digital scale. My ball park figures for a plane not yet
completed are based on some numbers from completed Lyc 601XL's. And that
is north of 800 lbs empty weight. I hope I'm pleasantly surprised. I'm
just guessing that the weight on the mains would be at least 650.
Another thing. Not to offend, but I'm converting MM's to inches and do
the chart C in Yankee inch/pound moments. I've been doing W/B in that
format for half a century and I'm too old and ornery to change. I can
build in metric but flying is another thing. When I was working for the
man, I had been handed many manifests in kilos and even Stones. No
problem. Furthermore, I've given some thought to moving the datum to the
prop hub so that I don't have to compute with negative numbers. It does
say "experimental" on the airplane after all. This will conform with
most every thing I've flown in the past 40 years. Except for my 46
Luscombe and anything else certified before there was an FAA.

To each his own. I just can't imagine going back to feet and inches.
I do woodworking and worked as a surveyor in my younger days so I've
even worked with decimals of feet - yuck. I've been looking for
metric tools so when I go back to woodworking, after the plane, I
don't have to revert to the 17th century. Metric tools are just not
available locally, I guess I might have to order them from Canada.
If you are talking about using a digital "bathroom scale" be aware
that it may be less accurate than an analog one. They still use a
spring balance, but they have to include a digitizer too. I'd stick
with a high quality dial scale. The Taylor Professional, which I
have upstairs, goes up to 330 pounds. I think I picked it up at
Sam's Club a few years ago for about $35. Someone suggested
calibrating the scale with known weights, which is the best thing to
do. Maybe a few sacks of cement? 90lbs each if I remember right. If
you calibrate, the actually reading isn't as important as
consistency. If the readings are consistent, you can factor out the
errors.
BTW, calculating wights and balance for the scale is exactly the same
as it is for the plane. You can reasonable use a lighter scale and
place a board between the scale and a support. The same math you
use to figure W/B is used "in reverse" to get the true weight of the
wheel. The support needs to be the same height as the scale, and
should be a "knife edge" or round so that it can roll. The goal to
make sure the support allows the board to pivot freely. Be VERY
careful with such a setup. Don't want to drop a plane.
Keep us posted on what you end up doing, and how it works.

His main concern was to make sure the paperwork was correct and
everything was properly labeled and placarded. He did look over the
plane and suggest some minor issues that needed correcting. I don't know
how carefully he checked the math, the W&B sheet I used was published by
Zenith with the limits printed on it. All I did was fill in the blanks
and calculate the moments and CG.

My nosewheel load was a little over 300 lbs and it was just easier to
put three 50 lb sandbags on the scales to verify accuracy than to mess
with five or six.

My 701 will have the VG's and no slats. Cruise speed will increase,
fuel burn will be lower and landing the same. VG's worked great on
our 601 HDS and expect the same with the 701.

Randy,
I used one bathroom scale that I had calibrated using a scale in the Dr's
office. I made paltforms for the wheels with no scale. Be sure to level
the airplane both fore and aft and side to side every time you take a
reading. I used a hose and clear tubing to make a level to level the
airplane fore and aft. I set a 4 foot level on the top and boosted the low
end to get it level so I would have a good reference for the measurements.
I also set it across the fuselage top for side to side level. I repeated
the measurements to be sure nothing changed.
