Like Rowland l am concerned with the structural integrity of the airframe (motor
mount stressing). Adding 40lbs of ballast adds at least 152lbf to the vertical
inertia loads (at LIMIT condition, n=3.8) and also may pull the local CG (of
the mass supported by the motor mount) forward. Special factors increase this
to 304lbf (ULT, n=3.8, SF=2.0 for composites) into the load-bearing fuselage
structure. Similarly, (but lower) increase in load occurs for side, fore-aft,
etc.
Hopefully some CG calc checks and/or simple config changes will yield a cure.

Thanks everyone for your responses to my weight and balance issues.
I am now pursuing the possibility of an issue with the scales.
Ivan also warned me not to add any weight to the engine.
It's great to have a group to go to for instant help.
Thanks again,
Bill

Bill,
The only way I can imagine your main gear being forward is your landing gea
r frame may not be positioned correctly. I highly doubt that. I doubt tha
t the tail planes and rudder are filled with a lead based filler, and you p
robably didn=92t use a lead filled tail wheel so I see no way you need that
much weight.
Scales are a pain, I have to have mine recalibrated and certified every two
years for about $500 and I=92m tired of it.
Use known weights and check proportionality of your scales. Typically on t
he recalibration they check 250 pound increments to the scale limit. Mine
right now stay linear, but now one is dead and, one creeps up at about 2 po
unds per second, which is disastrous amount so only one scale works now aft
er doing nothing but sitting.
Go slow, take your time, and double check. I agree, a 40 pound counter wei
ght forward of the firewall is unacceptable. There is no part designed to
take that.

Bud,
I checked the measurements multiple times and also did as you noted below.
Still get the same measurements using your method. Guess I=92ve got a sca
le problem. I will try some other scales with some friends at the airport
that have weighed other planes.
Also got a note from Ivan warning against putting extra weight on the engin
e so I won=92t be doing that. Hopefully it=92s just my scales reading inco
rrectly at high weights. I=92m also going to try loading them up with know
n weights to check.
Thanks for the help.
Hope you have a good week at Sun-n-Fun!

Rain and frontal passages this time of year is always a concern for a day o
r so.
I don=92t want to insult, but make sure you are measuring the correct joggl
e. Basically it is the cowl line. If you are using the front of your cowl
or the joint line for an XS that would be about an inch and a half off if
you are measuring from the joint line or cowl face. The measurement for th
e zero datum is not the cowl face. It is the original prop flange distance
of the prototype Classic.
The joggle on the molding of all Europas is 29.25 inches aft of the datum.
Level the plane at the door sill or your level data point. Drop a plumb b
ob from the left and right joggle and draw a line between them. From that
line measure 29.25 inches forward of that horizontal line and you have the
zero datum. Measure then the main and tail wheel for the mono from that po
int.
Recalculate your datum using the above and take a hard look at the detail i
n chapter 6 of the POH and I believe you will solve your balance issue.

Bud Yerly

Bud,
Thanks for the response.
Don=92t guess I=92ll get to stop by Sun-n-Fun this year as the boss has sai
d NO even though we will be close going through Tampa on the 6th=85.
Hope it doesn=92t flood you out like last year.
Here=92s what I=92ve got:
912ULS
Monowheel Classic with tail wheel mod and 1370 lbs. mod.
With the plane level, using the front face of the cowling as station 0 per
the manual.
Tail wheel at station 208 (78.5 lbs.)
Main wheel at station 46 (Manual says it should be around 47 to 47.5. I=92
ve checked and doubled checked but still get 46 inches.) (683 lbs.) That e
xtra 1 ' 15 inches would sure make a difference.
Battery on top of the passenger foot well.
Nothing in the rear other than ELT and strobe power supply under baggage ba
y.
I=92ve checked the scales and they appear to be weighing correctly but will
check again. They weigh correctly with me on them.
I just finished a bracket that bolts to the gear box and plan on adding 30
lbs. there to balance things out and keep CG within limits for most flight
configurations.
I will probably take it to the airport and get some of my buddies to double
check me with another set of scales.
Thanks,
Bill

It is rare to have a Rotax 912S or 914 tail heavy.
If your aircraft has a very light panel, a 912 (80HP) no exhaust muffler, i
s equipped with a light weight wood prop and the battery in the rear, I wou
ld expect that may happen.
(Typically a mono tail wheel weight is around 80 pounds. Your 30-40 pounds
sounds like you put in S-Tec servos from 1970 in the rear, made com wire a
nd antenna out of #2 cable to get that heavy. Also, a Deutz tractor gasola
tor (about 10 pounds) from 1965 added also would increase the tail weight t
hat much.)
Solutions:
Move the battery in the rear to the pax footwell.
A constant speed propeller is expensive but ideal if you need weight. Airm
aster 332 3 blade 26 pounds)
If you added heavy structure for autopilot servos that weighs 10 pounds api
ece, get rid of them.
Finally:
Recheck your scales. (I always stand on mine each to make sure each scale
is dead on and still calibrated well right before I weigh.)
Always make sure the tare weight of structure raising the tail to level fli
ght is subtracted out. Check the math.
Make sure the fuel tank is empty.
Keep us posted. It=92s probably just a math and weight error.

Subject: Europa-List: Weight and balance
Hello everyone,
After 20+ years I am now close to finishing my monowheel classic.
Initial weight and balance shows the aircraft is tail heavy and needing 30
' 40 pounds of weight added in the engine compartment to get the CG where
I want it. The current empty weight is 801 pounds.
I would like to ask what others have experienced, where they added weights,
etc. Currently I=92m planning on adding weight on top of the Rotax gear b
ox as there are available bolt holes and room for the weight (5x5 steel bar
).
Thanks,
Bill

I built my tri from the book without weighing anything and without paying
much attention. The W&B turned out to be almost exactly what the book
predicted.
Whenever I have came across a heart stopping incident during the build it
was always due to a mistake or a misreading that I had made. (and I made
quite a few)

Hi Bill,
Something is definitely wonky. I would start by checking your scales. You noted
in the original email a total weight of 801 lbs. However, in a subsequent
post you break out the weight for the main wheel at 683 lbs and 78.5 lbs at the
tail wheel. This only sums to 761.5. Where did the other 40 lbs go?
Regards,
Erich

Eric,
The 801 included 40 extra pounds I was planning to add to get the CG within
range. 683 + 78.5 + 40 = Approximately 801.
Checking the scales is definitely next on the agenda. If things don't fall
into place I've got someone else I can get to weigh it.

You can probably confirm the tail wheel weight with bathroom scales. Sounds a little
heavy to me if it really is 78 lb.
For reference, mine was 68 lb. Main was 744 lb. for a CG at 59.67 in.

BillI presume youre fully aware of this, but I was astonished to see how the weight
on the tailwheel varied when the airframe was out of level (fore and aft)Im
sure youll find the gremlin soonF.
