yeh mate I'm an Aussie, just finished wrestling a few crocodiles as a matter of fact... Private Read knows im aussie. I noticed a DSE battery in one of his pics.. hehe
Mate strap a V8 to the bloody thing, that will get it moving! jk
What are u using it for, I like the idea. I would love to rock up to work in a wheelie bin! lol
Um seriuosly though,, it will be dificult because of weight distribution.. Its top heavy with a base with small surface are. U will need weight on the bottom...
Are u gonna ad an extra 2 wheels to make it more stable, otherwise it will just drag the bin...
for power u might want to rip off the engine from one of those tiny petrol moped things or use a hight powered electric motor with low rpm (>250rpm depending on wheel diametre). I would suggest building a base to sit under it so u can properly mount wheels and room for motors n shit...
good luk
