Subject: | Fund Raiser Lagging Last Year By Over 30%... |
As of the 13th, the Fund Raiser is currently about 30% behind last year in terms
of the number of Contributions. Yet, oddly the number of messages posted per
day is up by 10 to 20% on the average. It costs real money to run these Lists
and they are supported 100% though your Contributions during the Fund Raiser.
Won't you please take a minute right now to make your Contribution to keep
these Lists up and running?

Clive.
My understanding is that the stall strips are there to ensure the pilot
gets tactile warning of airflow breaking up just prior to stalling. As
far as I know they do not make the actual stall more benign. maybe
someone who has flown with and without the strips could tell if they
make a difference to the behaviour at the stall.

Be careful on placement as they can cause the stall speed to be raised
which is not what you want. The other way to go is to fit a stall
warning device.

Subject: | Re: Stall strips |
The mechanism of action of stall strips is to force the stall to
initial at a different section of wing. It does so by forcing the AOA
to increase over a local region and thus must raise the intrinsic
stall speed. The nature of the stall is effected by putting the strips inboard
and thus moving the initial stall from a possible outboard location
(interfering with the ailerons), to inboard.
Thus strips increase stall speed and alter the stall flight characteristics
by design and intent.

Subject: | Tight control stick |
Hi all,
We discussed it here before, but I have one of those kits that has a lot of tightness
in the control stick when moving it left and right. I've heard various
ideas to fix it and only saw some slight improvement with putting a lubricant
at the base of the stick.
I was having the plane inspected by the EAA inspector last week and he thought
we should try to get to the bottom of it. We loosened the assembly at the base
of the stick but it didn't help much.
Then we loosened the two bolts at the aft end of the control, back where the CS06
bush and CS08 crank bolt to the CS06 bearing. We saw immediate improvement
even though we only loosened it a bit.
Obviously there's something binding here and I assume it is the way that the flox
pad cured... something wasn't lined up right.
So, for those of you that have had this problem before, what's the best way to
go about fixing it. Keep in mind that my cockpit module is already installed since
I bought the kit that way. I can barely get to the bolts much less make any
drastic changes to the flox pad. Maybe insert some shims? I'm just wondering
if someone has already figured this one out and could save me some head scratching.
Thanks in advance,
Dan

Hi! Dan
Way back I had such a tightness in my control sticks when the control
assembly's were connected up but I found it before the cockpit Module
was installed. However I also had made provision for aerosol can
lubrication "later in life" with holes drilled into the tuffnol bearings
to receive the aerosol tube, in fact the rearmost bearings have
permanent lubrication tubes through the bases of the seat backs. So I
injected " BRASSO" or copper polish solution and sat for about two hours
oscillating the control sticks back and forth. I then flushed out the
Brasso solution with harmless solvent/spirit until it ran clean, then
injected some light oil........problem solved. In my case it was useful
with the cockpit module in the "diving mode" since it allowed the
solvent to wash through any black abrasive polishings.
This at the time caused lots of amusement but it turned out to be an
effective fix. In fact someone developed a mechanical or electric
motor/drill crank to drive the assembly......Have fun!
Regards
Bob Harrison G-PTAG Europa Trike Kit 337.

Hi Dan
We purchased A-265 with accelerated cockpit module. In 2004 it had loose
aileron movement. Then when it came time to bond in CPM, it began to get a
bit stiff. Ends up that it was assembled with some grease that expanded
the tufnel. Since CPM was out of plane, was able to beat out aft bushings
and used a flap wheel to enlarge. The front bushing was binding as well.
It was not only the shaft to bushing fit as far as up and down goes, but
front and back as well (thrust) was binding. We purchased some pig oil
(lard cutting fluid, handy stuff for hacksaw and drilling and other
cutting operations) and some abrasive compound from McMaster Carr
www.mcmaster.com
The compound is pretty amazing stuff, it begins as a cutting compound,
then turns to a polish, then it disappears. They say it is even safe to
use in an engine, it will not keep on cutting.
Problem with many lapping compounds is they will embed into something soft
and cut away forever.
Be prepared for a yellow slimy mess though!
