Hi Don, I disagree. Scratchbuilding is something done in all subjects of modelling, and whilst this part is for a helicopter, it’s not just copter builders who may have an idea on the best approach, or nor are they the only ones who may benefit from the discussion.
If I was after a super glossy, mirror finish for a display team fighter jet, would I not be wise to go to a car building forum to see how the achieve their mirror like finishes?
