 =====Summary=====
-It is a fully operational Simchair MKIII compatible remix of a very nice B8 flight stick replica, originally by schrodingers_cat. It is designed for use with a new i2c controller. It contains an Arduino Pro Micro inside (sketch included). The trigger has two positions: half-press (intercom) and full-press with a click (radio push to talk). When the trigger is fully pressed, a half-press button is disabled by the software, so your sim will see these two positions as entirely separate buttons.
+The B-8 / MC-2 Grip has become the most popular control grip in aviation.
-Components
+This grip has seen action in fixed-wing aircraft such as the A-10, and rotary-wing aircraft manufactured in the United States and abroad.

-PTT TS-1202 button is glued with hot glue to the left half part just under the PBS-10B2 tip, which goes into the trigger (adjust its position so the PBS-10 button tip will push to the center of it). Fix wires with hot glue (make sure screw holes are not covered with wires!), add some glue to an ethernet cable. After joining halves of the stick together and tightening (be gentle!) screws, attach a trigger with m3x40mm screw. Insert the screw to around 80%, add a small drop of hot glue to fix it in place, insert it fully, wipe any leftover glue with a paper towel (use a knife if needed, hot glue can be removed easily). Put an M8 washer and a nut on a bolt that protrudes from the bottom of a stick.

 Adjust stick height to your liking, cut the aluminum pipe accordingly, then route an ethernet cable through the pipe and crimp it as a regular ethernet cable.
