An excellent addition to any flight box.

The PRESTIGE RC 4-in-1 driver has a hardened tool-steel tip which resists corrosion and an ergonomics and lightweight alluminum handle that holds up to 4 sized tips 1.5, 2.0, 2.5 and 3.0

All 4 screw driver shafts are designed to use with only 1 handle for space and weight saving.  They are designed to fit nicely inside the handle when not in use.  Easy to store, no worry to go hunt for the correct size.  All are stored inside one handle.  Once you have this, you don't want separate screw drivers any more.  You will love having 4 wrenches in one small pocket.
