Bill, you might consider a material that has a bit less grip than
nylon, such as Delrin. Another idea would be to have one side of the
block covered with leather, that would reduce the grip, but provide
sufficient friction.

Yep, you pay for that ethanol percentage one way or another. 100% ethanol will
reduce mileage by about 30%. Do the math sometime on those savings with E85.

Hi
Another hint - avoid ethanol gas blends - I found I took a big gas mileage
hit when I filled up with an E10 blend.
Using a 17' U-Hail I was told to expect 12mpg. This is what I got even when
in the mountains after the E10 was burned off. I was driving 60mph+ for the
1,100 miles back to Edmonton. Going slower was not an option.
Cheers

NW Builder DinnerMy friend John Hilger in Bend Or. sent an email
suggesting that we should come up with an addition to the rudder pedal
system we have designed. Thanks to John we are now considering two
optional features. First, a gust lock that will work for the pedals and
stick, and the second an effective servo adjustable rudder trim. We have
two concepts under consideration, however we need some help from flying
RV10's.
We need to determine the amount of pedal pressure required by a clean
rudder without trim tab in level flight. We are assuming 3 to 5 lbs. How
can this be measured?
Thanks in advance for your help.

Hi Paul,
It was great meeting you last Saturday. While not yet flying the following
email excerpt may help.
Vern Smith (#324 finishing)
What trim force do you think you are getting? I had sent an e-mail to Vans
asking what input they thought would be required. They told me that a 5 t
o 10 pound force as measured at the bottom of the rudder pedal should take
care of any 'normal' trim, 25 pounds could be required to compensate for ta
keoff forces. I have been crunching numbers on the torsion spring bias syst
em that I had designed. I am having difficulty getting the required trim f
orce without overloading the trim servo motor, or limiting the travel too m
uch. A combination of the two systems may be just the ticket to realize th
e benefits of both. Again I really like the different approach, thanks for
sharing. Jason Kreidler - #406174 Partner Build - Finishing

| Subject: | Re: Rudder Trim Question |
Paul-
I would suggest that you keep the clamping rudder trim concept on the table and
compare it with a servo setup. It works very well and you can easily design it
with a breakaway force allowing override from the pedals. I can get away with
a "personal" big screw setup that has an "iffy" override but to be offered to
the general public it must have the override feature.
The obvious advantage is the clamping approach is simplier with less expensive
manufacturers cost. The not so apparent advantage is it fuctions with much less
force.
A servo implementation needs force to move the rudder and overcome friction in
the cable system. The clamping design uses the friction to help hold the rudder.
Difference in forces required is two times the friction.
I can see where the gust lock fits well with the pedals but its a little harder
to visualize the rudder trim. If you want to spin the rudder trim off as a seperate
product take a look at the work I have accomplished. It needs a few more
parts to add a breakaway feature and I think a builder would rather buy than
build.
Good Luck,
Bill DeRouchey

Well, as promised ..... between forest fires .... I googled for
jackscrews. I started with '12 V jackscrew' and got all kinds of weird
stuff .... so went to '12V linear' and hit paydirt. There are a lot of
sources out there. The price isn't bad if you consider a Ray Allen trim
servo is $145!!!!
http://www.route66supply.com/store/page26.html in the $120+ range
http://productsearch.machinedesign.com/mdproducts/12v_linear_actuator
has listings for 515 companies, and no, I didn't check them out.
http://www.servocity.com/html/12v_linear_actuators.html has them for
$100 .... max speed .5"/sec.
or look here:
http://www.dcactuators.com/
I think that with the linear actuator and the torsion spring concept
..... there's a very good solution to the rudder trim scenario.

I went from about 32 mpg with the "old" fuel to 30 mpg with the 10%
ethanol blend. And of course it costs more. What a bargain.

If Van's Aircraft sold the P-860-5 governor for the wide deck Lycoming
IO-540 engine, you wouldn't even be having this discussion.
The P-860-3 governor is for the narrow deck Lycoming IO-540 engine,
which has a different gear ratio to the front mounted governor.

I believe all the 10's I built where around 2550-2600 out of the box, I
just
mark the arm and shaft and move the arm one spline.

Dick,
It is...Here as I posted before is the response from MT USA direct from their resident
expert and this guy really knows his stuff.

all P-860-( ) governors are basically the same. The - ( ) number only refers
to the control arm position and the max. rpm of the governor. To change the
control arm, loosen the 6 screws, turn the entire center portion to the
desired position, tighten the 6 screws and safety.
To change max rpm the set screw on the high rpm stop is turned
counterclockwise (out) to increase rpm and clockwise (in) to decrease rpm.
If there is not enough adjustment possible ( 1 turn = 25 rpm) the control
arm must be reset on the spline one notch at the time.
All this can be done on the plane.
To have MT Propeller USA, Inc. modify the governor max. rpm would cost
approx. $100.00, unfortunately the control arm position must be adjusted on
the plane

| Subject: | Rudder Trim - Spring Bias |
I have been doing a little testing of my spring bias trim system. I did not
measure rudder pedal forces required but the spring bias system has almost
enough force on take off so that only a little right rudder pressure is
required and the same for slow flight. Otherwise for normal climb, cruise
and descents the trim system will center the ball. It was easy to install as
Vans aileron trim servo is used as is and 4 holes drilled in the bottom of
the tail cone to install it. The turn around pulley bracket is simple to
fabricate and bolts to the elevator bell crank housing assy. The hardest
part was pulling additional rudder cables from the trim servo arm back to
the rudder horn. Also, having 2 rudder cables attached to the rudder horn is
the one thing I don't like about the system. I already had a 5 wire cable
installed in the tail come anticipating rudder trim at some later point when
I built the plane and a Ray Allen LED trim indicator and switch on the panel
with wiring completed. The trim forces are fairly easy to overcome so run
away trim doesn't seem to be a big worry. All in all I'm very happy with the
system. Frankly, the idea of clamping the rudder cables to effect trim seems
difficult for me to accept.
