Before there were engines and propellers, there were dreams.
Centuries ago, Leonardo da Vinci drew a sketch - a strange spiral that could lift into the sky if only the world were ready.
It was an idea too early for its time, but never forgotten.

Today, ROKR brings that dream to life with the Da Vinci Helicopter (CGL01),
a mechanical 3D puzzle that lets you rebuild the genius’s vision with your own hands.
Each wooden piece fits together like poetry,
from the double-helix wings to the six-cylinder radial engine that hums with mechanical rhythm.

When you light up the red-orange core inside,
it glows like the heart of a furnace -
a tribute to the age of invention, where imagination powered every gear.

Connect it to the Industrial City Series,
and watch it move in harmony with other machines -
the Morse Telegraph sending codes,
the Oil Rig pumping life into motion.
Each one runs on its own, yet together, they form a living, breathing miniature world.

It’s not just a model.
It’s a reminder that even before mankind could fly,
someone already imagined it.
And sometimes, that’s how progress begins -
with a sketch, a spark, and the courage to look up.

 Keep dreaming.
Because just like Da Vinci’s Helicopter,
imagination still has the power to defy gravity.
