thanks cap!

Thats was exactly what i was thinking. I was going to use like a 3 inch pvc pip for the hull and then like 1 1/2 or 2 inch pipe to put the motors in out side the sub. i was basing the whole idea off the puddle jumper from stargate atlantis, like i had said before. while i agree witht he whole back motor being removed, i have not decided. thanks for the opinion.
