Okay, now I'm in deep trouble...
When dry-fitting the upperhull on the lower part, I noticed that the side(left) was bend a bit outwards. I figured that with a bit of glue it would probably be fixed....
It isn't...

Because the upperhull is a VERY delicate piece of model (M88A1 builders will confirm this), I can't use to much force on it to make it stick, meaning every time I let go of it, it keeps coming outwards... (taking a lot of glue and plastic with it)
Is there anyone who can help me get this piece of @#$%^ back into it's original position??
Taping it to the rest of the tail doesn't work, after a day of drying it still comes off....
help please....

okay it is kind of sticky situation or not really

try this
cut 0.3 cm x 5 cm standart styrene sheet(can be really anything that can be glued to plastic) pieces and glue them inside of the hull to support the glue outside while positioning where you want ( i would suggest CA and accelerator)
and use clamps to hold it over night

did it make sense ?

Thanks,

Can you get a #11 Knife Blade into the area? If so, you can lightly score the joint until you're able to gently reposition the part.

If not, can you get a brush into the area? If so, then use a bit of Tenax7-R to soften the joint enough to let you reposition the part.

A couple of suggestions if I understood you clearly...

Are you going to build this one with an interior? If not you can make some support barsand glue them to the inside of the upper hull. Take measurements of the distance that the upper hull would be if in the correct position. get some square stock styrene or even thick pieces of plastic sprue. Cut the pieces the proper length and glue them to the inside from side to side. Start with pieces of shorter sprue or stock and glue them in at the upper portion of the hull and work your way down with more pieces cut to proper length to draw the plastic hull inward to the proper width. By using more than one piece of stock and doing a little at a time you won't stress the hull and you will be able the get the proper shape back. Take your time and don't hurry the process. Let each piece dry completely before moving on to the next. If you have any more problems or you don't understand this process PM me and I will try to draw some type of diagram and scan it to you.

Thanks for the help guys, I will go and try this...
The small (Not for me) problem is that the hull is quit thick and therefor tends to keep bending outwards, I hope that fixing (No, I think I'll wait a few years before starting interiors) bars will work, alltough at the moment it looks like it will keep pulling them apart....
we'll see,
Gunnie, I didn't understand this part


Thanks a lot guys!!!

(wish I tried to fix this before putting the A-boom into place... )

"Scoring" is dragging the back-edge of your knife blade along the glue seam. You don't want to cut through the plastic completely - just scribe a line to make a bend easier.
