Hi forum,

A little teaser of what I have been working on for the past 18 months. More information will come later

RC Sound Cannon (0 min 41 sec)

Hi, I made a live demo at a local giant scale meeting, here is a video.

Rc gas kanon (1 min 46 sec)

Cool. How much will the system weight and what size air tank etc is needed?

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
