i dont belive battle bots allows flame throwers. the guidelines clearly state the weapons allowed are only of the teathered type, ergo no guns, arrow, tazers, flamethrower's. etc.. there was another bot crushing comp however i remember watching, it might be allowed on that one they had some pretty neat stuff. can't remember what it was called tho. i always wanted to build a bot that would grab the other bot and drill holes in it.
