I can not measure the plans as I have not yet bought...I am assembling my shopping list.

For the tank, the recommend a 12 oz which seems way too small to me. Anything large capacity is larger so this is why I needed to know if a 16 oz would fit (so I do not have to buy a bunch of tanks or pay more shipping)

In terms of the control rod, yes 4-40 is in order...but what does GP include? (i.e. do I need to order this too)
