Reinforced gearbox shell, dedicated to replicas equipped with V2 gearbox.
It is made of zinc and aluminum alloy, which makes it lightweight and durable at the same time.
The shell is equipped with openings for bearings with a diameter of 8 mm.

The feature of this shell is that it is adapted for the microcontacts included in the set instead of the classic, rarely used plates, which significantly improves their trigger response and extends the life of the lipo batteries.
