Subject: | flaperon bracket mounting...IV |
--> Kitfox-List message posted by: "Randy Daughenbaugh" <rjdaugh@rapidnet.com>
In addition to what Vic suggests here is a trick I got from this list some
time back. This is to make the spacer slightly angled. Make the two sides
that the hole goes through non-parallel. My angle is about 20 degrees off
of parallel. I used it several places where it was too tight to get the
rivet puller head in. It gives just enough space to make it work and the
slight angle on the pull seems to make no difference at all to the way the
rivet expands.
My "rivet cheater" is about 3/16" at the thick point.
Thanks and apologies for my bad memory as to who it was that provided this
to me.
Randy

Lynn, Make a spacer about 3/8 inch long with a hole large enough for the
pop rivet nail to pass through. This should provide the clearance you need.
May take a few try's but it works.

As I recall Model I and early Model II Kitfox Kits were shipped without
mass balance weights. Some of these aircraft experienced flaperon flutter at or
around Vne. This resulted in service bulletin #3-Vne (reducing the Vne) and
service bulletin #20-Flaperon Mass Balance (Mandatory). These service bulletins
along with all Kitfox service bulletins can be found at www.skystar.com Click
on Builder Support then on Service Bulletins.

I think what you have is pretty close to being accurate. As I recall, about
that time there may have been a Kitfox in England that shed a flaperon due
to flutter. If this is true, then it probably helped with the decision to
go with the balance weights. My first Kitfox was an early model II that I
purchased partially built from a gentleman who purchased the weights as a
result of the bulletin. They came unfinished, but good quality.

I do not believe that a Kitfox ever shed a flaperon.. However, the close
cousin (AVID) did have at least one.

You might be right about that John. If so, my apologies. Since at that
time both had the same setup I'm sure that both Kitfox and Avid subsequently
mandated the weights, which (IMO) was a good move.

Right you are Darrel.
This was the reason for service bulletin # 3. One Kitfox damaged the mixer
bell crank (overseas), the other lost both flapperons.
This SB is from Denney Aerocraft Company back in 89, issued 15 of March.

As the story goes... They were detached from the trailing edge in places....
Supposedly they never departed the aircraft. That is what I was told.
Although that is not how the service bulletin reads.

Subject: | Re: ZERO oil temp? |
--> Kitfox-List message posted by: "Lowell Fitt" <lcfitt@inreach.com>
Ray, It would seem that this is a pretty common problem. Mine shows zero
temps until I am airborne. A friend's was exactly like mine and he said it
eventually repaired itself. I am still waiting for that to happen. I doubt
it is the strictly needle as has been suggested, because when it begins to
catch, it will jump around a bit before giving a steady reading.
I called Westburg and they give me a test to check whether it is the sender
or gauge. It amounts to disconnecting the sender from the back of the gauge
and then powering the meter.
If the meter reads more than half scale it is the meter. If the meter reads
less than half scale it is the gauge. Mine is the gauge and I am flying
until annual conditioning inspection time when I will send it back for
repair. My guess is that all these similar problems are gauge related and
that it relates to an intermittent power connection to the gauge.

Actually both Kitfox and Avid have shed flapperons. Dean Wilson (Avid)
early on added counterweights (before the accident) as the airplanes
gross and speed increased on the later A model and B model Avids.
Kitfox added weights after an accident due to flapperon flutter. The
Avid that was lost was an Amphibian in which the owner left off the
weights to save weight. He had flutter when he exceeded VNE during a
test flight. If John Larsen is reading he can supply more details.

Subject: | Can't find service Bulletins |
--> Kitfox-List message posted by: Lynn Matteson <lynnmatt@jps.net>
I went to Skystar's site and couldn't find the service bulletins today.
I found them the other day, and fortunately I could trace my history
and found where I had visited SB #34 recently, and just changed the
address to get to SB #3. Why can't I get there directly? When I visited
the other day, there was a prompt right on their site that took me
directly to the SB's...what's going on?

Subject: | even more on mass balance weights |
--> Kitfox-List message posted by: "Andy" <fultz@trip.net>
It was actually AVID that encouraged the use of and supplied the mass
balance weights for both AVID and KF in the early days. Dan Denny would not
believe there might be a problem until the first KF shed its flaperons.

Actually both Kitfox and Avid have shed flapperons. Dean Wilson (Avid)
early on added counterweights (before the accident) as the airplanes
gross and speed increased on the later A model and B model Avids.
Kitfox added weights after an accident due to flapperon flutter. The
Avid that was lost was an Amphibian in which the owner left off the
weights to save weight. He had flutter when he exceeded VNE during a
test flight. If John Larsen is reading he can supply more details.
