Subject: | M3X Roll Problems |
Test flying my Mark 3X after initial flutter problems found that flaperons
were impossible to move in flight and all roll control was by secondary
effect of rudder. Balance rods were fitted to balance tubes, but otherwise
they appear normal on ground.
Anyone had any similar issues?

Further to this, I figure I've 'over-balanced' the ailerons as Kolb did not
include the anti-flutter kit with mine and it only came to my attention
through this forum. Maybe someone could send me pics of their balance rod
installation as I'm thinking mine must extend too far forward of the hinge
point.

Hi Tony,
Don't know about the xtra , but on my
MK3 the twin sticks were about 1&1/2
In.too long and when pushed forward and to one side or the other,
The off side stick would hang up under
the tube that runs from the panel and
Back overhead that the windscreen
Is mounted on. Causing the Ailerons
to lock up. Hard to find the problem
Because of my panic when aileron
Control is lost. And my reluctance
To voluntary enter that condition.
For me a simple cure--I cut 1&1/2
Inches off the sticks.
Hope your problem is as easily cured.
Good luck
Frank

Tony M/Kolbers:
The aileron counter balance rods are just that. They should extend far
enough forward to balance the ailerons.
Here is how I balanced my ailerons:
-Disconnected the aileron push/pull tube at the aileron horn.
-Adjusted the aileron counter balance rod fore and aft until it balanced
the aileron.
-Replaced the aileron push/pull tube at the aileron horn.
Works for me. No aileron flutter after installation of aileron counter
balance weights.

Tony you didn't state if you had dual controls or not. I changed from singl
e control to duals in my X-tra and had the same problem. Moved easy on the g
round but not in flight. Found too much play in the controls and a leverage
problem with the duals. Went back to single control and flys like a dream a
gain.

Subject: UltraStar Project for Sale.
Contact: Mr. Chuck Moon, Wimauma, FL. CELL: 813-390 1222
Price: $1,500
This is a sale by third party following the death of the acft owner before
he could complete the repair/restoration.
Background: Ultrastar, in garage storage since approximately 2002. Suffered
right wing damage when
wooden prop disintegrated at cruise and the prop fragment passed upward
through outer portion
of wing. Engine was shut down and acft was successfully landed without
further damage.
Structural damage appears confined to aft portion of one rib, but fabric
removal around damage
will be required to verify. Airframe appears straight, with no observable,
significant corrosion problems evident.
Condition of fabric on remainder of airplane is unknown, but looks OK.
The following YouTube link provides photos taken this week:

Engine: Cuyuna (Carburetor is missing). Propeller requires replacement.
Seasoned Kolbers on this list may remember The late Skip Staub, CDR, US.
Navy, F8 Crusader driver extraordinaire
and Kolb enthusiast. This Ultrastar was Skip's and he was flying it over
Palmetto, FL when the prop failed.

Subject: | Re: M3X Roll Problems |
I just sold my Mark 3X with flaperons about 6 months ago and while the
airplane has some very nice features, the roll control is not one of them.
They are extremely heavy and quite ineffective. But that is typical of
simple flaperons.
Here are a few points to consider:
The balances you are talking about are mass balances to control flutter.
They have no measurable impact on control feel. Aerodynamic balances
lighten the control forces and there are some pictures on the web of
"spade" types on the M3X, I am not sure how well they have been tested.
Spades work fine on sturdy ailerons like on aerobatic airplanes, but I am
not sure the Kolb is meant for large control deflections. As John H likes
to say, be careful making big changes to Homer's design.
Note that the tube that is the forward spar of the flaperon looks like a
torque tube at first but when you look at where the hinge points are you
can see that it is actually in bending. To prove this you can move the
flaperon to full travel using the mass balance and then gently twist in the
same direction. You will see the tube bend with the stick at its stops.
Like others I made a small change to get more mechanical advantage and
lower the force, but I gave up aileron travel in the process. When you are
flying the airplane you can move the linkage with enough force but the
flaperon barely moves at all. This is because the tube is bending and
absorbing most of the motion.
As an aerospace designer, I can tell you that flaperons are compromises.
They move together to lower stall speed, which mine did some, and
differentially to roll the plane, which mine did poorly for the reasons
mentioned above. Ailerons are very different. They have less area which
makes them easier to move and it is way out on the wing where it produces
relatively more roll control for a given deflection.
If I were building a Kolb I would go with traditional ailerons.
