Hi my friend @airbum!
I used liquefied styrene after assembly to strengthen and together seal some not so positive bonds, like the curved area of the fuselage that meets the corresponding WWW (Wheel Well Wall - LOL), as I want to have the maximum bonding strength, to reassure the rigidity of this BBB (Big Beautiful Beast - LOL2). I just make sure to wipe (with my finger or other suitable tool) ALL excess liquefied styrene, as it may cause plastic melting and the inevitable sink marks at places you do not want too.
I have rarely used liquefied styrene to assemble parts, mostly in cases that the mating surfaces had obvious gaps and I was lazy to sand them down...
As for the wings, I definitely agree with you, my friend, though I wouldn't object leaving them moveable at a - say - 1/72 F-14 snaptite kit, assembled by a teenager who is new to modelling.
My 1/32 Mig Eater definitely does not fall into this category. Moreover, the Tornado has those distinctive wing mounted pylons that remain parallel to the flight direction (of course!) regardless of the wing position. This means internal mechanisms, that are not accounted for at the Revell kit: you would have to rotate each one of the four manually, everytime you would change the wings' angle...I don't like it.
PFP QCs have been promoted to PFP QARs (Quality Assurance Representatives). This means stricter acceptance criteria and expanded areas of examining. You can bet they will go for max speed optimized retracted wings...the structural rigidity becoming a cosideration...
Thanks for following!
