HIROBO "Shuttle" R/C Heli  ZS Tail Rotor Unit Case Open Type Part # 0402-228.  I haven't seen any of these available anywhere for a long time.  The Tail Rotor Gear Box Cases are very easily broken..  may possibly be used on other Styles (Generations) of Shuttle R/C Helicopters..  Really don't know, so YOU have to do Your homework before ordering!!   Any Shuttle that has a broken "Tail Rotor Case" that You just can't find, and this had been whacked the last time You hit the ground and are pieces missing around the bolts, then this is (and possibly the Shaft) what needs to be replaced!   I have finally come to the realization that I need to start thinning out some of My collectible inventories.  First, some History...  Many Years ago, several importers of the Hirobo Radio Control Model Helicopter brand would buy specific parts in "Bulk" quantities (Head Components, Tail Gear Box and Tail Rotor parts, etc.).  They would then "Package" the pieces with their own labels (Gorham Model Products (GMP) comes to mind) and assign their own specific part numbers to the pieces.  Enough about "The Good Ole' Days".....

  These Tail Rotor Gear Boxes are NOT one of those items.  This is a Genuine Hirobo sourced Replacement part and is in the original Hirobo Packaging!

     So, if You have a 2nd Generation Shuttle in the garage, and have been looking for a Replacement "Tail Rotor Gear Box" (they always tend to get "Cracked" (another one of those words I never thought I would use) from the Terra Firma in a crash...   So here is Your chance to get Your Heli back out and burn some more fuel!
