Thanks for the reply. I had heavily reaserched tormenta 1 but hardly taken notice of tormenta 2. It's great to know that this idea is possible and that many have done it in the past. I'll hopefully try and take a look at some of these robots you mentioned as I think I previously seen some of sewer snake and the insides but didn't pay close attention to it. One question that I would like to ask is do you think that a cordless drill motor combined with some 6 MM chain would hold enough power to compete with some of the other flipper out there? And is it worth using 2 motors for increased power?

best regards
