Here are some simple pictures on the frames I use for my matoran mocs. If you wish to see any other instructions, feel free to let me know. Also, please give me some acknowledgement if you choose to use some of these techniques. Thank you!
About this creation
These frames can be seen with armor here.
Matoran Frame 1.0 - built primarily with poseability in mind. Its only weakness is restricted head movement.
Characters that use this frame:
heavy armor soldier
matoran bike rider (blue one with Surge mask)
This frame has the ability to move hips from side to side. Great for making those epic acrobatic poses.
Matoran Frame 2.0 - designed with poseability in mind while addressing the problem of limited parts. Slightly taller than Frame 1.0, it not only enables normal head movement, but allows for the use of any type of bionicle head piece.
If you wish to use a metru head, simply flip the HF leg part over. Simple as that. Mocs that use this frame include:
and that's it so far. I will probably make more when I get more time.
