REFLECTOR: ROLL TRIM

[Christopher Martin]

Tom,

I have the roll trim installed, the standard factory servo. I never use it. I have been flying for 560+ hours and ,flat out never use it. 

I do however, use my auto pilot all the time. Originally had the Navaid wing leveler and then changed out to the EZ Pilot as made by Trio in San Diego. I only needed to buy the control head as the servo from the Navaid was the same. I'm very happy with the EZ Pilot and recommend it.

I also installed a altitude hold. as made by TruTrak.  It is a single servo connected to my trim spring. I'm also very happy with it. It is a small servo and requires that the plane be perfectly trimmed prior to engaging. But, once it is set up it works perfectly for up to an hour until conditions change enough to warrant a retrim.

Don't waste any effort on the roll trim servo. Spend the money on the Trio auto pilot. That's my recommendation.

I know this topic has been probably discussed so much ... that it makes your teeth hurt ... BUT I NEED MORE INPUT!
 
I installed a really cool roll trim.  It is basically Alex Strong’s servo connection to the aileron bell crank.  It gives a constant spring tension and snaps back when pushed or pulled against it.
 
However, I am wondering something.  And I can’t answer it because I only have 6 hours on my plane.
 
HOW IMPORTANT IS ROLL TRIM ON THE VELOCITY.
 
No theories please.  I really want to hear from guys who are flying.  Do you use it?  Really?  Would you miss it?
 
It seems to be a pain in the a$$ to have constant tension (even light tension) on the stick.  Has anyone one away with it?
 
Thanks,
