I am thinking of bashing together a set of replacement arms for Astrotrain. The need to fit into the sides without changing the appearance of the alt modes, so I would be using the same shoulder and flat piece that is on the outside of the arm. Can anyone suggest a bot that has slide-out arms and possibly pull/flip out hands, that would be able to be fitted to Astrotrain? Elbow movement would be a great bonus but is not absolutely necessary. So far, I am thinking G1 Swoop arms would be the easiest to modify to Astrotrain.

 

which Astrotrain??

 

G1 Astrotrain. I've always thought the gimpy arms he has need to be fixed.

 

Can anyone suggest a small figure that has lower arms which fold back over the upper arms? Perhaps a legends class figure? This would allow an elbow!
