?? Thoughts...
« on: May 16, 2010, 08:03:00 AM »
  Mornin' guy's  I am building another model and on the outboard tip is a stationary tab, I am thinking about making it adjustable, and my thought's are make a .010-.015 metal tab to insert into the tab so that it can be adjusted as needed.
   What are your thought's and why would you do it that way???
        thanks

That way works but I like to use 1/16 copper tubing instead of a metal tab. File a few grooves in the tubing before inserting so the epoxy has something to hold onto.  8)

I myself like the hinged adjustable tabs with the quick links.  I have the metal tabs on a couple of planes and they are always getting bumped.

As I read this about a trim tab on a CL wing, I often wonder if a Trim Tab on a fixed wing acts like a control tab on an aileron, or an actual trim tab for the whole wing.

Let's say tab is in the UP position, does the "trim tab" actually force the wing lower or does it try to increase that wing into a higher angle of attack creating more lift and flying the wing up?  That is how elevator-aileron trim tabs work on conventional un-powered control surfaces. The tab moves opposite to the control position so as to fly the surface into the position to releave stick pressure for the pilot.
Without a control surface, I just wonder about that.
This model's wings looks like props with so much warps. However with trim tabs and some not shown, it flies very well on RC. Just wonder if CL would be the same or opposite!
