what about a hydrogen powered flipper which uses combustion to flip opponants


Have a look at cordless nail guns - they have a small butane cyclinder and a ram with an igniter at the back. Hacking one for a flipper would be dangerous, but copying the mechanism might be possible. From memory, the gun is good for 2,000 nails, so one butane cartridge would last several events in a bot.

It's not a easy as you think. you'd have to make it two stroke and there are all those issues with fuel to air ratios and a lot of other issues that make it a big job. The results would be quite awesome, but you could achieve something similar by just building a pneumatic flipper with off the shelf components Razz

use an electrical ignitor.

Either a timed spark or constant spark discharge near the nozzle will work.

Not that I think flame throwers are a good idea.
