As for the focus, the camera I used sucks. The lens is outta sync with the eyepiece so what I look at with it is not what the pic turns out to be.
The camera is on of those slim mini ones that requires very specific conditions for a good shot and I have yet to find the said conditions.
Thanks for some of the tips Smarty I'll try them next time I take pics. BTW the elbos are hinge with a rotating joint father up the arm.
Like this: Forearm-Battle Droid Elbow-Upper Arm-EP1Battledroid arm for the rotation joint-Shoulder.
3----o--=0 <---Grievous' arm.
I'll post pics of my ARC troopers later, again they are on the blurry side, but just take a look and LMK what you think of the overall look of them.
