Other than the pre-installed stab linkages, the kit comes with none of the basic hardware that most kits come with.

As a result, it's necessary to figure on your own what type of hinges, horns, air cylinders, etc will best suit the kit.

For the horns, I purchased a few sets of control horns from BVM and used these for all 3 control surfaces on each wing. Appologies for the lack of focus on one of the pics, but I'm sure you get the general idea - just file a slot in the control surface for the horn to fit into, and a corresponding wider slot in the mating surface for the horn and clevis to be able to fit through.

To ensure that the horns are instaled equally on both wings, I made up simple jigs using a wire to locate the horn hole in the desired location, and plywood jigs on either side to hold the wire in the correct location. This is a variation of the technique used in most of the BVM kits that I've built, but with a plywood part on BOTH sides instead of just on ONE side. This arrangement allows me to still get the desired location even with the plywood parts spaced far enough from the horn to allow me to get in between and apply / tidy-up a glue fillet
