Brief Description: Fitting the Horizontal Stabilizer
Once the forward portion of the HS is drilled and secured, the next step is to set the angle of incidence for the HS. Van's plans call for a 3/16" spacer underneath the rear HS spar and the aft deck. I found that in order to achieve the desired 0 degrees incidence, I required 9/32" instead. I contacted Van's about this and they said that you need to put whatever spacer underneath that will do the job. At this point, after confirming the measurements several more times, I drilled the rear spar of the HS to the F-711C bars.
