Posted: Mon Apr 13, 2009 9:45 am Post subject: Aileron trim

I am finally finished the rebuild on my 601HD and have flown again after 

2 years.  The left wing is exceptionally heavy.  I have changed to wing 

incidence some and adjusted the aileron push rods.  Both gave some 

improvement but did not correct the problem.  I temporarily placed a 

fixed trim tab on the bottom of the right aileron and problem solved.  

However I am considering adding an adjustable aileron tab.  My plans do 

not include drawings for this tab and I can find nothing on Zenith's 

builder's page or Ch601.org that gives plans.  Can someone that has 

installed a tab on an HD or HDS contact me off-line as I have multiple 

questions like how to install a MAC servo. dimensions of a tab and where 

on the aileron to put it.  I already have a MAC stick grip with buttons 

for elevator trim and extras for the aileron trim.

Thanks for any help

Jerry,

I've got a page on trim tabs and an electrical drawing of the wiring 

necessary to make it work. Perhaps the pictures in the link

will help. The electrical drawing would help you with the 

interconnections. This has worked well in my HDS.

Good luck,

 Thank you far the reply. I see you used  a trailing edge tab like I did 

on the  equator I know ZAC uses a tab set into  the aileron. What Servo 

did you use?  RAC has several listed based on the throw  (length of 

travel) and I suspect the longer  One (l-inch ) would work best. 

External to The aileron would make retrofit alot more  single.

I'd be inclined to use the 1-inch servo

do not archive
