They were contacting plastic on the VF-22 for sure. As for the Alpha's I can't say for sure, they are in fighter mode, (never transformed for obvious reasons)...Also on my 1:60 ver. 2 ElintSeeker, it is sitting in fighter mode on the 3 points of the stand, wings and underside of nose. The X-Wing I coated with Testors Dullcote. The SDF-1 is in cruiser mode and it is resting on the bottom of the upper legs and the middle front part of the underside. I can provide pix later if you guys want.
