Now for something different, hope you enjoy!
Two highly detailed Lego sets from my collection:
Set 3451 from 2001 (have had in my collection for 17 years now, the decals are degrading seriously), 577 pieces, Size: +_40 cm wingspan - in red, brown and tan bricks
Set 10226 from 2012, 879 pieces, Size: +_50 cm wingspan in green, grey and tan bricks
Of note, at least to me as Lego collector, is the evolution of the size, detail, novel use of Lego elements and building techniques between the 2 models....
***These are official Lego sets, so beyond sourcing them they only required rudimentary Lego building skills from my side***
(.......having said that, biplane wing rigging wires can be challenging, even in a Lego set....)



Both have detailed rotary engines (cylinder pots rotate with propeller) but only 8 cylinders in model due to Lego building technique restraints (v 9 cylinders in actual aircraft)


Set 10226 has some functionality with ailerons and elevators actuated by cockpit joystick



Set 3451 only six cylinders...


cheers
