Has anyone else had any problems with the Lambda mini, the wings on mine do not fold down to their correct angle and I don't want to force the issue and break the model. They are only a few degrees out but it's noticeable!

I have heard that it is a semi common problem. The issue is apparently thick layers of paint in the joint. If you can't gently force them into place, try taking an exacto knife and scraping away some of the paint that is blocking it.

Thanks I'll give it a try

Try a little light duty oil, I used some on mine and they move the full spectrum..

All three of my space busses have this problem too.

With my first one I sat watching some tv (battlestar galacticia to be exact) and just kept moving the wings up and down, sits in place nicely now.

Been meaning to ask around if anyone on here has pulled one apart

On all 4 of mine I just took a nice new x-acto and patience. On the underside you will notice the excess paint in the channels. Just do some light trimming and testing until they move easily. All of mine can now be positioned completely down.

Mine has the same problem with 1 of its wings, so I'm just extra careful with it.
