To all of you flying with aileron and/or rudder trim, do you have trim position indicators and do you find then useful? Thanks.

I use my GRT EFIS for elevator and aileron trim indication.  Work great and

they are very useful....preflight being the most useful time.  I have a

separate indicator for the rudder trim......not sure it is as useful.  The

rudder trim does not have much authority and I just center the ball with it

once I get into a steady state....climb, decent or level flight.



Also, I did not put in a flap indicator and I regret it.  I am doing it this

annual.  I put markers on my flaps and use the P-1 LOT device (pilot..me),

but don't like having to turn my head to see the flaps during pre landing

checks. I have a flap positioning system, but like to check flap position on

final......

You probably don't need anything on the rudder trim, but it's actually

nice to see where it's set for the aileron trim.

Thanks for the info. Your response prompts another question. I am just finishing up my rudder trim a la Tim, Vic and others. They both used 11" of hinge for their tab. If you do not have enough rudder trim authority, how much tab do you have and how much do you think it would take to have enough authority? If I am going to need more tab, now would be the ideal time to change it.

Jim,



I HOPEFULLY will get this right for Rene', but I don't think he

meant to say it doesn't have ENOUGH authority, more that it

doesn't TAKE much authority.  The amount of trim required

is pretty small.  With the 10-11" of hinge that I have, it

doesn't need to move very far, and you can easily see the effect

with the skid ball.

Jim. Tim got it right.  I have enough authority to do what I want, it will

center the ball in climb, decent and cruse, I just meant to say that it did

not exert a lot of force and no matter what position it is in I have no

trouble using the rudder. I can not remember how many inches I used, but I

think it was 11 - 12 inches.  Now for the elevator trim that is another

story, take off with it in the wrong position and you will need two hands to

fly the plane....don't ask how I know..........

I recently finished my phase one flying and I found that I did not  

pay much attention to the rudder trim indicator. The aileron trim  

indicator was something I would reset after refueling, but did not  

really need it.. Pitch trim indicator, I used every takeoff. All  

three indicators are shown on the Vertical Power display in my airplane.
