YF-21 Transformation Problem

[Brand-X]

Hey I have a problem with my Yamato 1/60 YF-21, can't seem to find any posts relating to this issue.

When transforming into fighter mode, I can't seem to get the backpack to properly snap down near the shoulder joints. I try to snap one side down, then the other pops up, though one side seems to be looser than the other. I've checked and it doesn't seem that anything specifically blocking the top part from snapping down properly, I have the small doors out of the way, and I've tried it without the arms and legs attached to the figure, so nothing's blocking it there. I think maybe the swing bar mechanism might just be too tight? Has anyone else had this problem?

Thanks for the video, but I've watched that one before. At 4:20 he skips past the problem I have, where he simply says that everything is locked down. Perhaps I just have a lemon? I'll try and post some pics in the next couple of days to better explain my problem.

Post some pictures. Maybe I can't tell you what you are doing wrong. And I can upload some of my 21 in fighter mode.

It would be easier to help if you have pictures or a video of the exact step that's giving you difficulty.

But if I understand your description correctly, perhaps the area preventing you from snapping the backpack down are the shoulders themselves. The shoulder pauldrons must be rotated to a certain position when stowing the arms in fighter. Failure to do so would not create enough clearance for the backpack to snap down in place. Hopefully that's the issue.

Edit: to clarify, I'm talking about the shoulder covers (that rounded armor piece covering the shoulder joint)

Okay here's some pictures that may help.

First off, we have the left side. As you can see in the first picture, the top is flush, as the shoulder joint is pegged into the wing.

However on the other side, we have this:

As you can see, the shoulder swing joint doesn't peg into the wing. I can manually press it down and it'll snap into place, but then pop right out again.

It seems the metal bar is slightly bent. Have to study the last picture a little more.

[Brand-X]

Well, I believe the bar is supposed to be bent into a bow shape, but here's a picture of the bar itself (Please ignore the door being pushed down near the intake, that was just in this picture, so that's not the problem)

It's bent both sides the same, yeah it's not the problem. Will check the pics with my YF-21/VF-22's when I get home.

[Scyla]

So first deliberate guess since I have not handled my VF-22S in a while.

Is this clip snapped in. I can spot a difference there between the left and the right side.

Here is a third video maybe this also helps:

[Brand-X]

Yup that clip is snapped in, so it's something outside of that.

[Scyla]

Hm... have you already transformed it correctly into Fighter-Mode or was it that way right out of the box?

[Brand-X]

Well about the first thing I did when I got it was transform it to Battroid so I'm not sure whether it was like that in the box, but every time I've transformed it to fighter the problem appears.

[Scyla]

I'm asking because it could be that the part is mis-molded. I have this problem on my YF-29 where one of the hip armors will not sit flush because something went wrong when the part was molded. Maybe it was yanked out of the mold not fast enough (or too fast) causing this problem. I have no idea if this is possible so this might not be the problem.

So if you try to push the top part down do you feel resistance?

[Froy]

Here are some pictures of mine.

I don't see any problem with the metal parts. Maybe the plastic is warped a bit.

Use the last picture as reference and check is that plastic part is symmetric.

Having gone through it more thoroughly I feel like the entire back is just slightly warped. It feels like when both tabs are snapped into place the plastic is bending along the backplate slightly, it seems maybe just a little too straight. Along the central fuselage everything is tight but around the intakes I can feel a gap when I push down. Anyone have any ideas on a fix? I suppose I could just try to gently bend everything downwards

[jenius]

It sounds like a clearance issue, something is getting in the way somewhere along that side. Wish I could see it in person to help.

[Brand-X]

Yeah I've gone through it thoroughly and I can't see anything caught or otherwise pushing upwards against the backplate. I really am starting to think that the backplate is just slightly warped or something, as when I hold the side down that I'm having troubles with, the other shoulder often pops out instead.
