It's less of a "piloting" situation and more like just placing her in an empty space..

Various collab poses

The Frame Arms Girl Hand Scale Gourai has been released as a collab kit with Hasegawa's MechatroWeGo. The product name is Gourai with 20 MechatroWeGo "BROWN" — a pretty rare cross-manufacturer collab kit.

The MechatroWeGo is conceived as a small robot for kids to use for commuting to school or leisure activities. It doesn't have a source anime or original work — it started as someone's personal creation that gained popularity and eventually got turned into a product, which makes it a pretty unique item. Hasegawa, well known for scale models, has released it in plastic kit form across several versions, and similar products have appeared from Nendoroid and others as well. It seems the collab came about because the scale of the child pilot inside and the Frame Arms Girl Hand Scale are roughly the same size.

Opening the box, you might be a little caught off guard — there's another box inside, and that's where the MechatroWeGo runners are. Rather than feeling like a proper cross-company collaboration, it honestly feels more like Kotobukiya just bought a Hasegawa kit and dropped the whole box in (...). Sure enough, the Hasegawa manual is included as-is, and alongside the Gourai manual there's one additional color guide manual thrown in.

The MechatroWeGo is a snap-fit kit, and true to Hasegawa's reputation as a scale model powerhouse, the overall parts finish is extremely clean. No step mismatches, great build feel, and even the color separation is well done. That said, they don't seem to have as much experience with articulated kits, and the moving parts feel like they're missing that last 2%. The sub-arm used to slide the cockpit in and out is particularly flimsy — the connection tends to pop apart during use, and the sub-arm mounting point on the body is weak enough that it could snap. (It happened to me ..) On the gimmick side though, there's plenty of fun stuff — top and front hatch opening, a back cover that opens up, and more. Articulation is smooth and joint strength is decent enough.

The Frame Arms Girl Hand Scale Gourai is the same configuration as the existing release, but with one extra runner of mint-colored armor — MechatroWeGo's No. 1 color — added in. It seems intended for use when doing a collab with the mint-colored MechatroWeGo. On top of that, one Frame Arms hand runner has been added so the MechatroWeGo can hold various weapons from Kotobukiya kits.

As for the main collab feature... the sizing is roughly in the ballpark, but once you actually put her in, it doesn't feel like a great fit. The control stick handles sit too low for Gourai to grab with her hands, and there's really nothing to secure her in place. It's more like just setting her inside an empty space. Since neither side originally designed this with the other in mind, I guess that's just how it goes.

All in all, Hasegawa's MechatroWeGo has some durability concerns in certain areas, but the overall build quality is clean, and the snap-fit experience in particular is noticeably smoother than what you'd get from Kotobukiya. The downside is that Gourai doesn't feel like a perfect match — it's probably more accurate to think of this as a kit that just happens to be a compatible size. Still, it's a genuinely unique collab kit, and it deserves credit for being a fresh and novel idea. :-)
