I have started design and getting components to the new octo. I am building it using aluminium, and anodising it a funky colour. I have found some boom clamps from a Razor 600E tail boom costing £4.99 for a set of 4...nice and cheap. They are also the perfect size, taking a 3/4" ali tube (19.1mm diameter) which looks nice and chunky. I have bought jdrones 880kv motors and 30A ESC's from www.buildyourowndrone.co.uk Here are some images that I modelled to make sure everything goes together okay. I will get the center plates water jet cut so they are nice and neat. I also decided to house the esc's & power distribution on their own level, with enough space for airflow.
