Marv,

Thanks for the response.  I did not do any sanding on the GM4 phenolic
blocks.  Common sense proved to be the better judge in that case.

I have tried every combination that I could think of with these holes on the
aileron idler arms, and the bottom line is that they line up 1 15/16" apart
or they are so close that it would be almost impossible to disconnect them
for wing disassembly.  I haven't heard anything else from the list here
about it.  I suspect that the extra inch dimension will make a difference in
how the controls handle, but whether that is a good difference or a bad
difference I can't tell unless I see the whole linkage working.  I don't
know how much travel the idler arm does from full aileron deflection to the
left or the right.  But, I can guess that the closer the angle between the
idler arm and the control rod becomes to a straight line the bigger the
chance of the control being harder to correct back to neutral position.

I'd like to hear from someone who has the hardware bracket kit installed to
find out.  I'll give it a couple days and then contact Lancair if I don't
hear anything.  I've got to order some rivet tools anyway in order to do the
job, so I have time.

Thanks,
