Superb model sir !
Absolutely fantastic. Although even to my eye the fin and tailplane do look a bit small - not your model, I mean the donor aircraft.
We were taught navigation on our ATPLs by a former Buccaneer navigator. He was a human computer - he could do complex nav maths in his head that would take us rookies 20 mins to do using tables and calculators. Amazing.
Could someone briefly explain the tailplane flaps. What were they, why were they needed and why not design the tailplane to move over a greater range?
