Re: aileron trim tab (LIVP)
I installed the standard size, and the test pilot said it was too
small and under-effective. So we increased the size off the
hinge. Photo below. The hinge length is standard, only the
width is increased. Carbon fiber sheet.

Can anyone give me some information on
the size of their aileron trim tab. I used an 8 inch long piece of
hinge. It seems like I need a little more mass, as fuel burns off on
one side I do not have enough trim left. Its pretty effective most of
the time. I installed per book for the LIV. Help!Brad
I ended up riveting a flat plate of AL to
the original tab to almost double the number of square inches of tab
surface area. The builder's manual recommendation is too small. Also
it helps to keep your wings balanced to within 10 gallons for trim
reasons. Many aircraft have lateral fuel imbalance limitations for
this reason--the Cirrus SR 22 is one.
I'm not sure about the IVs, but on the ESs we have
added between 50% and 100% to the trim tab area by riveting on a piece
of aluminum. Because of the thickness of the trailing edge of
the aileron, the hinge alone doesn't do much.
