Hirobo Gigas 550E


The new Hirobo 550 electric helicopter - The Gigas 550E was first shown at the Shizuoka hobby show in May 2017.

Designed using many Shuttle and SDX parts, Hirobo made new carbon frame so the model
can be used as a 550-600 class model.

The concept for Gigas series is this model can transform itself to many different models
depending on skills and needs of customers. It can use wide ranges of current Hirobo
parts from Shuttle, SDX, and Freya/Eagle lines.

Hirobo are planning more new option parts in the future, so each pilots can build truly their own Gigas.
