Here we have all the carbon bulkheads ready for prep. Prep invloves sanding the edges for glue adhesion.
Very little, if any fitting is needed as they fit just about perfectly.

......
These peices get tacked with CA glue awaiting final epoxy glue up. Use the bellcrank to space the tabs to ensure
they will fit when dry. Tiny shims are used between the bearings so you can crank down on the bolt that holds
the bellcrank. The tabs that hold bellcrank rest just under the horz. stab spar. Dry fit only now, this the LAST
piece that gets glued in as the the driveshaft tube goes in first. (driveshaft tube rests at top of this bulkhead
and does not get glued to it. split collars hold the alu-tube to the upper fin braces instead. Pics will be in next
page.

......
   The front crossmember attaches to the alu tube with a split collar as shown below. All in all, three collars
hold the alu tube. One up front, and two in the upper fin bulkheads as shown below. We leave about 3mm space
between bend in alu tube from floor.Later we glue a scrap of ply to attach under here and it also serves to insulate
the glass from any heat the tube may build up.

......
 It is a good idea to taper these collars for the fin braces. drill a 2.5mm hole for mounting with blind nut from
behind or regualar nut. Here is the tail rotor bulkhead dry fit.  The cable housing is trimmed to within 10-15mm
of the tail rotor coupling.
