How difficult is the build of an ERA?

[J.Jensen]

Thanks for some very good replies.
DanEC: do you have a link to your build? I´d love to read it

The somewhat ridiculous Norwegian laws about self-building does not allow the body to be attached to the frame even. The bare frame needs to be inspected by the governing body doing the controls. I think I can get away with the pipes and those things attached to it, but it specifically states the frame is to be inspected prior to body assembly on it, but I think I would have the body painted by one of the shops ERA recommend.
I´ve done some sanding and body filler work on aircraft composites, but I hate it - and my skills with it does not match the finished result I´d want.

Are the FE´s trickier than other V8s?
