My name is wayne,I have just started building my vision and it seems I ran into a few problems.I had a problem getting the wing retainer pins to line up wound up having to dremmel out the boss retainers to get the wing on,horizontal stab has a lot of slop in it after I drilled and tapped the srews in it,I noticed rotating pin does not fit snug in fin pin too small and carbon fiber stab joiner fits too loose in fuse.Has anyone had this problem and what should I do to fix it
