Resources and help needed on bot schematics

Hi guys, I'm a model maker and I'm looking at butchering up some kits to make some of the transformers from the new movie, starting with Blackout.
Can anyone point me in the direction of the best resources to build a highly detailed and accurate model from?
Much obliged for any help, and I will of course share any updates with you guys as and when.
