The Tantalus is one of those models that was just not designed to actually be used.
The flight stand that they use on the webstore where it is sold doesn't even use the stand they provide in the box.
Here we have a flight stand kit with a specially designed adapter to let you put this model on the table for the first time on a flight stand.
It even comes with two magnets so you can magnetize the sail for ease of transport!
2x Medium Flat Magnet Flight Stands
2x Tantalus Adapters
2x Medium Flat Base Adapters
Resin Large Flyer Base
This includes EVERYTHING you need under the ship so you don't have to go shopping around!
