Bandai VF-31AX Kairos Plus - Hayate Type in Toys Posted Saturday at 12:48 AM · Edited Saturday at 12:49 AM by 100mega 5 minutes ago, no3Ljm said: I'm not sure if I understand your question properly since the DX VF-31A, engineering-wise, is the same as the VF-31J. The only differences of these 2 when it came out are the paint, head, fold carbon chest details, back leg missiles (instead of drone chambers) and the delta wings. And when you say engineering, are you referring to the transformation or the overall engineering updates on the body design? Because if it's transformation, then this new 31AX is still going to be 95% the same as the transformation of the previous VF-31. If it's design, then there's some body modification done to it to distinguished the difference between the 31AX and the previous 31. Unless ofcourse you were meant to ask the VF-31AX (Hayate) instead of 'VF-31J', then I'm looking forward to see a side-by-side comparison between it with a 31A once it gets released later this December since I didn't PO Hayate's. I guess I'm sort of asking about things I don't understand so sorry if it was confusing. I am personally trying to decide if I want the Hayate one with the fold projector or the new Hayate AX one. The shape of the planes looks pretty different to me like W-shape vs a diamond shape and since this AX, the diamond shaped one, is like the previously released Kairos I guess I was wondering is if people prefer one style of design over the other since the older Kairos has been out in the wild. I guess the transformation of each is pretty similar and the different wing shape is just throwing me off.
