I have a Starboard quick lock 2 fuselage. When I have tightened the screw to expand the fuselage and lock the front and tail wings, both wings can't seem to fasten properly. I am able to move both wings from side to side, especially the tail. Wonder if anyone else have experienced this, and is there an easy fix to this?

Bring it back to the shop where you bought it and have them sort it out. If you paid for service then you better make use of it. They'll likely replace parts under warranty as it shouldn't be moving like that.

Shop was also surprised at this. It is only a problem with the largest front foil. It is tight when I fasten it, but becomes loose after an hour or so. He was going to check with starboard if this is common or if there is anything to make it stay in place.

Tail is broken, I have another tail, and this one works fine.
