New arms for the KO TFC Aerialbots.
It has a couple of features like:
-swivel at the biceps (mushroom)
!!!You will need two screws for this!!!
(you can use the screws from the original shoulder piece or from the heads. In case you are switching out the heads for the ones designed by Steamshield.)
Also in jet mode the shoulders will just be a block, so harrier like vents yet.
I will make a version with some mechanism that will transform into a decent arm and have a harrierlike vent in jet mode.
But the idea with this one was to cut and glue the original KO shoulder on the cockpit/jetnose so you'll still have a harrierlike venting in jet mode. This will require some work.
You will also need to re-use the bottom arm piece from the toy. (see picture)
