what change is there in rudder pedal pressure and the ball or

Hi Richard.
not enough to notice. She will trim out to fly no hands for some minutes.
After that she can be kept reasonably straight with rudder only for a
while. Certainly long enough to sort out a map. Not perfect but as with so
many other things attaining that last few per cent is the difficult bit and
I for one won`t bother to refine things any further.
Cheers
Pat

My trim tab is not big enough, so I am pushing with the left foot no matter
what
I do. Winter project: new trim tab.

>>>>>>>>>>>>>>>>>>>>>>>>>>
i have mentioned this before so someone and they replied they would rather
have a trim tab,,,, but my mkiii has springs that pull the rudder pedals
forward,,, just put more tension or a bit heavier spring on the left
peddle. that way you don't have to install a tab, down side,,, when
parked the rudder will be slightly deflected when sitting on the ramp.

Hi Guys,
great suggestions about the Bungee to trim for a passenger, thanks!
Its fog time here in San Jose, but yesterday it cleared up in Hollister about
11.00AM and was calm and the airport was empty, so I went up for an hour. I
have two trim questions.
1/ I agree with John H about the prop wash on the tail for which I have to put
in Right rudder to compensate for. I topped up with a tad too much oil and the
left side of the rudder and top of the left HS was spattered. How big is your
trim tab , John? two rib bays long but how wide? 3 inches??
I think that will help eliminate yaw and right rudder input.
2/ I added an aerodynamic elevator trim tab and it works wonderfully. But I still
find that my M3X is unstable in pitch, ie, I cannot take my hands off the
stick for long as it will start to either dive or climb, depending on the
power setting and trim setting, and will not recover by itself. Is there a
way to set up the plane so that it will fly hands off? (in pitch)
Any suggestions are appreciated.
FrankD
PS, My engine is now running well, max CHTs around 310 Deg F, and oil temps
around 200, with EGT's below 1400.
Now I'm trying to get the radio noise eliminated!

Frank D/Kolbers:
Here are some pics with a spare rudder trim tab I made. Same, same what I
have on my MKIII, except I rounded the corners more than depicted on this
piece. This was also the first tab I tested, which covered 3 rib bays, and
moved adverse yaw the opposite direction in the same amount as it flew
without a trim tab. After I cut it one rib bay and to the dimensions
indicated below, it flew with the ball centered and feet off the rudder
pedals.
Dimensions are marked on the trim tab, but in case you cannot read them,
here they are:
Width: 14 3/4"
Length: 1 7/8" to the bend (35 degrees) with a 3 1/8 trailing edge.
Short side is riveted to the ribs with large flange aluminum fabric rivets.
I use aluminum rivets (hardware store quality) for anything that is not
structural because they are much easier to remove when it comes time to
change a component.

Pitch stability is primarily a matter of CG. If the CG is aft, the
airplane will not be stable in pitch. Get too far aft of the neutral point
and the aircraft becomes violently unstable.
I took a different approach. When I bought my Ultrastar, letting go of the
stick meant a nose dive. I added elevator trim tabs to get the trim speed
to about 40mph (reasoning that it _might_ be survivable an elevator cable
or something broke). I also have a bungee to pull more nose down trim, up
to a cruise speed of approximately 55 mph.

Don,
Thanks for the reply! So you think pretty easy with a 447? How? Done per plans?
