Huge K9 Makeover

K9 has been a bit neglected over the last few months due to the Dalek build and work on the new Droid. I thought it was time to give the electronics a make over. The original electronics design was more add it and see what happens rather than planned. K9 was a very fast build and as such the electronics were never really thought out fully. In the new design I have completely cut away K9's side panel giving much better access to the new system. The side and top panel will be easily removable when needed. The electronics systems is laid out in a very simple way giving access to everything. The batteries, motors, water system and compressed gas cylinder are all accessible by removing the whole top section leaving the drive unit.
Originally I used two RF units, I am now using one. Before all the LED's were switchable, now they are all running of a single circuit controlled by a single switch. The top panel and under body LED's are now all sound activated. Five circuits, sound, screen, LED, radio and ESC are all independently fused and switched. 
I still need to add some body touch switches to trigger some sounds via touch and need to add some motor cut of switches.
When the side panel is fitted you could not tell K9 has had such a make over. Problem is that I prefer the look when you can see all the electronics, maybe I should have a see through side panel.
