Brainless my friend. So did you add the drop tanks like in the weps tutorial? There is a tank called Tank1500_Tornadods. Did you add that? Also open the loadout.ini and make it look like this where the drop tanks is listed.
Loadout[01].WeaponType=BOZ107
Loadout[01].Quantity=1
Loadout[02].WeaponType=SkyShadow
Loadout[02].Quantity=1
Loadout[03].WeaponType=Tank1500_Tornadods
Loadout[03].Quantity=1
Loadout[04].WeaponType=Tank1500_Tornadods
Loadout[04].Quantity=1
Loadout[05].WeaponType=
Loadout[05].Quantity=1
Loadout[06].WeaponType=BL755
Loadout[06].Quantity=1
Loadout[07].WeaponType=BL755
Loadout[07].Quantity=1
Loadout[08].WeaponType=BL755
Loadout[08].Quantity=1
Loadout[09].WeaponType=BL755
Loadout[09].Quantity=1
Loadout[10].WeaponType=
Loadout[10].Quantity=1
Now open the Tornado_GR_DATA and scroll down to the weapons.

Assuming you have added it correctly to your weapondata.ini and did the above then you will be good to go.
