KNEX TANK with a mg with no chain.
it has a mg. and uses no chain peaces. the only exotic peace it uses is a orange gear. like a yellow gear it has the pegs sicking out of it but only has half the pegs. it can be made by cutting off half the pegs if you want. not very power full but that is because i am using a clasic motor. the motor has to pull bach the ram so to much rubberbands and the motor can not pull bach the ram. if made with a beter motor it could be stronger.
o and the last picture is of all my knex guns :)
