LOL i posted the same video some time ago in the "odd&ends" gone section Dre :D
For the fins i'll try to glue with the rest of the plane and after paint all... with some acrobatics :)
but here the su-34 start:
Will not use the kit cockpit but will scratch all things needed to see the opened access door inside the fron gear well, then starting to cut the bulkheads with the original piece as start template.
bulkheads needed are two for the back, one with the access door and the other are just as structure just after the ejection seats, also here cutted the front well that is not closed in the parts i've cut out
A rapid dryfit of the rear wells reveal this strange void removed after.. will replace with some evergreen piece
the two bulkheads after lots of cuts and sanding
heres the correct position of first bulkhead, the rigth and the left were i cutted the well must be filled of ... instruments
door hole
floors and bulkheads
glued some sprue piece as constrainer
and here a test of general disposition
and ready to go in the bed
