I was thinking the same thing but I have some aluminum foil tape that
would be perfect. It's the same stuff you use on furnace exhaust vents.
Just like aluminum foil but with and adhesive backing. I'll give that
a try tomorrow when I go to the field. The tape can be removed easily
but also will stay in place if it works well. If it does seem to work,
are there any drawbacks to using aluminum foil tape compared to a
braided sheath in terms of effectiveness?

I have a suggestion based on a problem we encountered on our Allegro. We
used a couple SS clamps similar to those shown in your photo, to help
stabilize the muffler which had a tendency to vibrate a lot and crack.
Inadvertently, we had one of the clamps making a relatively sharp bend (like
your 90 degree bend at the bottom of your battery) where the screw thread
slits were located. With the higher stresses at the corner and the weaker
part of the clamp, it broke. When we installed the replacement we positioned
it so that the weak part was not at the higher stress area and had no
problems since then.

Thom,
I purchased some new clamps and repositioned the bends so that no slot was
over a corner.

The rotor RPM was quite low at this point, the collective down and locked, with
my hand on the cyclic. Having said that, the thing scares me too, just so different.
We have decided that for our next project we are going to fit a gyrocopter

| Subject: | Drooping FireFly Flaperons |
Kolbers,
Yesterday, I flew to Hagerstown to my EAA 373 Chapter meeting. I lifted off
into the morning haze and did not climb above 1,000 feet agl to maintain
some horizontal visual range. I had a 15 mph head wind so I let the engine
run on up to make time. It took me 40 minutes to fly 26 miles or 39 mph
ground to ground. On the way home the haze had not improved. I throttled
back to 5,000 rpm so I would not get home too soon. One of the fun things
about the FireFly is to just be up in the air, to build time and to ride the
thermals. It took 28 minutes to get home or 57 mph ground to ground.
On the way home, I flew at an 40 mphi. Since the FireFly is trimmed out for
the engine running 5,500 rpm, I had to hold considerable back pressure. And
then the light bulb went off. I cranked in about one degree of flaperon.
The nose came down, the back pressure requirement disappeared, indicated and
ground speed picked up little and engine rpm increased enough so that I had
to throttle it back a little with no loss of altitude. These continuously
adjustable flaperons are just great for trimming to maintain a low drag
configuration.
Fly Safe.

Jim,
I painted my gap seal which is made out of Lexan with the same Poly-Tone
paint I used on the FireFly. Sticks real good, in fact you don't want
to change your mind later and try to remove it!!

Maybe I am misunderstanding your comments.
Understand you "cranked in about one degree of flaperon." Does that mean
you drooped or reflexed them about one degree?

I painted the top part of the canopy on a Dragonfly MK II with the same paint as
the plane. Just tape it off and rough up the lexan with sandpaper so the paint
will have better grip.

Hi Jack H:
That is what I thought.
Drooping flaperons or flaps pushes the nose down, requiring more aft
pressure to remain level.
Reflexing them will pull the nose up, requiring less aft pressure, or if
reflexed enough, you will then have to apply forward pressure on the stick
to remain level.
This is the opposite effect you got?????
Wonder why your aircraft responded in an opposite manner?

Mike,
I would try one of Rogers suggestions below if you don't want to disturb the
kill switch wiring, just have to tie one end of the shielding to a good
ground.
Let us know your results.
As long as thr fuel senders wires are shielded, the kill switch RFI should
not affect your reading.

Thanks for all the suggestions. I have good and bad news after working
on the airplane. The bad news is that the shielding did nothing. The
good news is that the problem has nothing to do with the shielding or
interference. My senders are bad. I guess that's more bad news. I
started thinking about the problem and realized this was a problem that
gradually appeared. It happed slowly over such a long period of time
that I just thought it has always been a problem. I'm only 36 and my
memory is already starting to go. The senders use to work fine when I
initial installed them. The vibration from the airplane is the cause.
I found that at 2500 RPM I could get the gauges to work fine. If I
tapped on the sender the things went crazy. I guess it's time to
contact the company and maybe order new ones.
