I think it’s the ‘muscles’ and the big beefy arms (apologies to Trogdor) which make it ugly - it’s almost leaning in the direction of some of the older Japanese toy designs.

   The tubes going into the head are nifty as well.

They were really difficult to get to work, so I’m glad you like them. I really like both that pic and the one of the head from the front.

The problem with the tubes is they need to be gripped from the side to prevent them popping out when the head turns, so I had to rework the ‘brain pan’ and the top of the torso armour to get it all in. Worth it though, because the head/neck area would be a bit empty otherwise.

   any chance we can get a look at the inside?

There isn’t much inside. I’ll try and get some more pictures later, but I can attempt to describe what I’ve done now - hope that helps.
  • The leg is a sandwich of a fuselage base part with a fuselage top, in grey.

  • The achilles tendon is a 6-stud axle threaded with bush/holding part/worm/holding part/bush.

  • The ‘holding parts’ are the kind with a smooth hole at 90’ to an axle hole. Each axle hole has a 2-stud axle in it, and the six stud axle goes through the smooth holes.

  • The 2-stud axles fit into the holes in two 7-hole (actually one 6- and one 7- because I didn’t have the parts) flat new-style technic beams.

  • At the other end, the beams have two 2-stud axles with a 2-stud 2-hole technic brick trapped between them.

  • This brick fits over jumper plates on the fuselage floor, and into 1x2 plates inside the fuselage ceiling (the holes in the studs lock into the pips in the bottom middle of the 1x2 plates.)

  • The two click-hinges for the knee lock into the other end of the fuselage parts.
The whole thing is completely loose until the beams and technic brick are fitted into the fuselage and the lid is closed. This makes it rather fiddly to assemble but very satisfying. Plus it goes ‘click’ when you close it.

I hope that helped a bit. Pictures will make it all make sense.

The joints inside the hips are much simpler - just a two-level worm gearbox made of normal and technic bricks, kept as small as possible. These use the rounded-off-corner spur gears to engage the worms.

   However, I don’t like the lack of hip articulation. Good forward movement, but it needs hip splay or rotation for the poses to look natural. Also, the legs, though cool, could stand to be a little bigger. If I were you, I’d make this mecha bigger, keeping the body and head, and giving it longer legs and arms. This way you could also fit in hip and ankle splay.

Yeah, my wife and I both thought it needs longer legs, and there isn’t really a reason not to try it out like that. I’m still not sure there’ll be room for hip splay, because there’s no room to manoeuvre (sp?) where the hips join the lower torso without losing the pilot or the nifty boat hulls, which I rather like. It’d probably need to use geared joints for any extra hip posing.

The big leg problem is that I built them to support just the pilot section (grey lower torso) and didn’t really count on the weight or scale of the upper torso.

My dream mecha would be able to sustain a proper foil or epee lunge, which would give very difficult conditions:
  • Front leg bent foot flat on floor (like Kaji)

  • Back leg straight out behind, about 30’ to the floor, with the back foot at 90’ to the front foot and flat on the floor.

  • One arm out behind.

  • One arm straight out forward from the raised front shoulder, with the hand able to rotate in the arm’s axis to be pronated or supinated.

  • Torso in plane of legs, with the head turned over one shoulder.
Ahhhh. One day.

Many thanks for the interesting comments,

Will
