This is currently a WIP. I saw an Astrotrain mock-up on another site and realized that he was originally intended to have better arms, unlike the gimpy arms he ended up with. So I am working on giving Astrotrain extendable arms that will still fit in train/shuttle mode without any change in appearance! So far, I have attached the arm extension part. This is rather difficult due to the way Astrotrain's shoulder joint is constructed. The cool thing is that almost all of the work can be repro'd and flipped for the other arm, only the piece that will have the other hand on it will need to be done again. I will probably offer these as upgrade kits once it is finished!
