After some procrastination, I've made a ton of changes to my design. Kinda regret making detailed instructions now that they're mostly obsolete... Anyways, the purple one has been the one I've been experimenting with. First off, made the design quadrupedal so it had better balance. Then, I realized I should probably try to make a gear function. After about 2-3 hours of experimenting with different designs, I realized there would be no way to have an internal gearbox while still having a way to attach the head piece for the "shell"/kanohi on the back. So, I decided on an external gearbox system. Definitely a little bulky, and I don't have any gears that properly fit the color scheme, but it's a start. After putting the rest of the build back together, I definitely think it was an upgrade. (The thornax launcher is also a fun little addition ) The gear function is nothing too special. All the limbs move in unison, though there is no lever/gear that can be turned to move the legs remotely. Here's a GIF of the function, I couldn't get the filesize low enough to embed it so I had to link it externally. Thanks to everybody for their comments and criticisms, I've been having a lot of fun getting back into building MOCs. The problem-solving aspect is so satisfying; I was ecstatic when I discovered a way to add a gear function after much trial and error. Next order of business: Find gears that fit the color scheme better, buy more purple and teal technic pin connector blocks (the "mata hand" pieces) so the back legs have a more consistent look and so I can make the upgrades to the teal Rahi too, and buy more technic ball joints.
