WIP-Mospeada classic mega size Eta Legioss

[F18LEGIOSS2]

Hi everyone,

I’m currently working on a transformable mega-size Legioss that I want to make as sturdy as possible.

First, I would like to get close-up pictures of the Riobot Sentinel’s arm and shoulder articulations, including all visible hinges and joints, as well as the folding landing-gear mechanisms.

I’m also looking for help creating 3D models — particularly the Legioss torso air vents — using SketchUp, since I’m just getting started with 3D modeling.

Thanks so much for your help!

The pose+ wasn't big enough for you? Looks cool, I wish I could do 3d modeling! I didn't have enough time for my hobbies

It’s really satisfying to build your own mecha when you have the means to do so.

Over 15 years ago, I watched Captain America build a Legioss in 1/32 scale, and I want to stay as true as possible to the original line art, just like he does with his creations.

Bandai managed to create the ultimate version of the VF-1, starting from the original 1/55 scale Valkyrie and going through Yamato and Arcadia, with improvements added at each new version.

With the Mospeada toys, I don’t really feel the same. It feels like they’re just making different iterations of the Legioss toy, rather than improving it.

So now that Pose+ is selling a 1/28 thru Toynami etc...

Maybe a Beta (Tread) comes next?

The hand prototype is bigger than expected It will be resized to the correct scale later

[jenius]

Well it's big but it's impressive!

I think you have it backward, the Legioss should be resized to the HAND!

It wasn’t easy to find a way to compress the arm without making it feel like a Transformers-style toy, but rather something closer to Robotech. I can’t wait to 3D print these parts

The stressed parts have been replaced with PETG instead of PLA.

It feels heavy and sturdy and I love it!The cracked PLA pieces will be replaced later.

Next, I’ll be working on the ratcheted shoulder joint, hand and missile hatches

It can be done!

I’ll need detailed hard-surface panels for the inner frame, along with well-designed missile hatches.

I’m open to any suggestions or design proposals.

Design proposal: my biggest pet peeve of every Legioss toy since the Gakken 1/32 is the door that swings over from the center with the sensor array connected to the bottom of it. In the line art, there is no door laying over the right shoulder. I think that center panel should flip backward or recess. The sensor array should rotate from facing the nose of the plane to facing thrusters and then the arm the array is connected to should pivot laterally and vertically to move the sensor to the right shoulder. As a bonus, this mechanism would also help with the creation of a Dark Legioss (you would simply delete the array and have no doofy looking door with nothing on it). 

Edit - Looks like the team may have thought the array would be stored in the chest?

Here are my design adjustments so the center part could sit flush on the right shoulder with the antenna (air brake could be installed in it) or slide down into position to form the crotch section in GERWALK and Battroid mod

Here are the missile bay based on the Legioss inner frame. I’m open to any suggestions and ideas.

A quick comparison between the first and second shoulders: the second one is 5 mm thicker

[F18LEGIOSS2]

Arm hatches will slide 5mm up to expose the missiles in open fire  position
