I agree. However, I believe that this would work like the flashlight. In servers, (Where you have no jump jet) When you find this item, it becomes like a pernament object when you wield it... Letme think. It could be like the Armour's which Pandan release.
You pick up the item, wield it, and then it changes your datablock to a datablock which can fly. Preferrably one which preferences can be changed in RTB
