Thanks one and all for the compliments!
To sum up this build for those who haven't seen or read the other thread on the RPF (its huge!):
This was mainly accomplished by replacing parts that easily identified it as the well-known toy. Starting from front to back:
--Nose cone: I cast the original in resin (it matches the large-scale Red 3 only, not the 1:24 ILM models) and then remastered it to the correct shape.
--Hull: All screw holes and landing gear holes were filled, and all the toy mechanisms (levers, motors, lights) were removed).
--Canopy: clear plastic was cut out
--Cockpit: Replaced with an Icons cockpit cast
--R2: Replaced with R2 from 1:24 Jedi Starfighter model R2
--R2 strip: Replaced with studio scale cast
--Butt plate: Holes filled and some parts replaced with casts of original parts
--Engine nozzles/turkey feathers: Replaced with casts of Maxi-Brute model rocket nozzles, correct actual heat sinks inserted
--Wing interior surfaces: Sheeted with styrene, panel lines penciled-in
--Cannons: Original bodies, gaps filled; brass tubing for barrels
--Plus a few other "secret ingredients" (stuff too minor to really bring up)
What I didn't do that I could to further enhance the project
--Create actual panelling for wing interior surfaces so panel lines would be real, versus drawn on*
--Fill all original panel lines and either re-scribe or re-panel fuselage and upper wing surfaces
--Remaster cannon bodies so as to be able to incorporate correct, real heat sinks*
--Light model
--Cut open rear (fixed) portion of canopy*
*Items I will most likely do on my next conversion (Red 1 or Red 3)
