I'm looking at the website and the details say "To charge the unit with CO₂ gas, S-Thunder's CDC series CO₂ cylinder with adaptor is recommended (Sold Separately)" So do i need a big can of CO2 gas with an adapter or do i need the CO2 cylinder? and does that mean i HAVE to buy the adapter because if it just uses like a Propane adapter then I'm set, also do i have to buy simtubes for this model?
