Yep, there are a lot of differences between the SHE & Yamato YF-19, they are far from the same beast: -
Yamato has landing gear, SHE does not.
Yamato's gunpod can attach in fighter mode, SHE's cannot.
The rear of the lower leg of the SHE has a complicated 'Origami' type folding design. The Yamato does not have this.
The SHE has a correctly sculpted canopy shape, The canopy on the Yamoto is the wrong shape and features a rounded lower edge, instead of the correct straight lines and angles.
The Yamato has that annoying triangular shape gap in fighter mode where the nose hinges, the SHE does not.
Due to dispensing with the folding lower leg mechanism, the shoulders on the Yamato sit far too high in fighter mode, making it less sleek than the SHE.
