Hey there guys I really do need some help here, My idea is something that has been done before but I want to do it with a twist. I wish to create a classic shock wave from a energon shock blast. I need to know what two robot arms to use for his robot mode as I do like the claw on him.I wish to try and get a decent arm for the other side but of course I need to put a cannon on it and well I wish to go a little different then the classic laser cannon.I was thinking a chain gun on it. I have already created figured out a decent gun mode and I have taken other modes I have seen of here as well. But what I don't know what to do is these two things 1.What arm to use for his robot mode. 2. How to re use his actual Shock blast cannon as the actual cannon for his gun mode WITH keeping the battery pack as well. I really need help here and if any one could help me that would be awesome.
