So, I spent some time today putting the final elements in CAD, I'll spoil you with a series of pictures from that before going on to boring details...
Above: The top armor removed to reveal the inner workings.
Above: A shot of just the inner components.
Above: Front shot showing how low profile the bot actually is. Yes, I know if it were actually for any sort of fighting I'd want the CF armor panels to go to the floor.
Above: And a top view.
It probably will need some extra mounting holes along the sides (and it def would if it were to see combat) but this is just a demo robot, the most dangerous thing it'll probably face down is an overly ripe gourd.
The more I think about it, a spinning blade bot, while showy, is a TERRIBLE demo bot because of how horrendously dangerous it is. There might be a later revision switching out the spinning motor mount for some sort of lifter or grappler. Actually, a grappler could be really cool to do and fairly simple given there are low cost servos that can lift a pound or two with a 4" lever arm.
So, minor setback, I found the only way to buy the eflite connectors on my batteries was either as part of the receiver board ($60) or as part of the charger adapter ($12). Good thing I only need 1 for the wiring harness. Speaking of which, FINALLY managed to get the GF interested in this little project and she agreed to help me solder together the wiring harness. Which is good because I'm actually really bad at soldering. But either way, I have the charger adapter so I can wire up a test set using some .1" header cables. At least get things driving and connected. The second charger adapter is on order from Horizon Hobbies thanks to my local hobby shop.
