OK I checked my kit for the rods and this is what I found.
List of Rods:
2X ~39.5" Long
2X ~15.75" Long
1X ~12" Long (metal)
List of Packs:
Fin
Wing
Canard
Engine Mount
Fuselage
Landing Gear
Hatch
Canopy (empty bag, hardware installed already)
Thrust Vector Tube
Nose Gear Pack
See pictures attached.
Looks like the two long and two short need to be connected together and the metal rod is used as a sleeve like Bob mentioned. The thrust vector tube pack has six threaded rods in it, which I believe are used to connect all the rods together to make the two push rods from the servos to thrust tube.
