Thanks.

At the moment it's about 600g without extra battery and controller for 1 cannon and 850g for 2 cannons.

There is no air tank but there is a propane canister. I have found a small one with OD 45mm and 150mm long.
I wrap it with heating wire for faster re-heating of the canister (canister gets cold when shooting which affects gas pressure and rate of fire) and a sleeve of neoprene for keeping the heat from the wire to the can, this adds 12mm to the OD and 5mm to the length.
A canister valve head is another 20mm to the length.

There is a lot more info in this thread along with another guy who I helped copy my results for collaboration purposes: https://www.rcgroups.com/forums/show...-awesome-sound
