Just reading ahead in the plans as I get ready to assemble the HS. I am wondering why the plans have you join the rear spars and doublers in the first step, then the last step has you finally assembling the HS-911 brackets and bearing. Don't you need to match drill the hinge bracket to the rear spar with a #12 drill bit? A test fit of the AN3 hardware with the spar and bracket is too tight. If I have to match drill after everything is assembled there is no way to deburr the interior of the doubler and spar holes.
