Apparently there was a problem at the Avipro factory with improper standoff heights; The standoffs at the aft pulley mount were way too short, and would have resulted in the pulley mount pushing out the fabric. Mark Goldberg from Avipro sent me a listing of the current factory standoff heights, and this station, and the one immediately forward were not installed correctly on my kit. The more forward station wasn't that far off, however and aesthetically, there was no compromise. Mark sent some extra standoffs, and I cut off the old ones and welded in the new ones with clearance for the pulley mount. I'll wait till I finish fuselage frame modifications before I prime and paint this.
