ok I just the CAr Robots version hes extrememyl awesome but his legs are a little loose right at the joint at the top of his legs does anyone know how to tighten that up? ive done it with ball joints but never with this type of joint

 

anyone?

 

I've got one but he's in storage and I can't for the life of me remember what type of joints his legs have. I suppose if you can take his legs apart to get at the inside of the joint you could add something to make the joints sit more tightly in their mounts.
Might be better to ask this question in the Radicons section.  

 

I really dont get this, what is wrong with yours?

 

the joint that lets the leg swivel forward and back its a little loose and cause him to sag in truck mode
