Hi sithlord.
With regards to add-ons to the pod, such as missile packs, or pilots, I would highly recommend building the model static, as the extra weight would simply topple the kit at that point. This can be done quite simply by taking a few minute drops of CA and dabbing it into the ball-socket (slow cure CA recommended) and then placing the Regult in the desired pose. This will handily eliminate any chances of structural failure.
