Boond,
Looks great! Is that the Clark profile? It is much more symmetrical then I'm used to seeing (other than with folks here). It looks like you've borrowed from Chris' formed-lexan cover for the alternator. Was that challenging to shape?
I agree, but disagree with Adam -
It is an awesome looking build. Agreed.
I think the inner third, in general - and spinners in particular - get a bum rap here. First there's the all-important aesthetic piece, which is that a turbine just plain looks better with a spinner (IMO). The spinner also offers weather protection for the blade root-ends, bushing and hardware. And, in the case of a variable pitch mechanism, I think this is a critical component. I'll concede the aerodynamics benefits may be minimal at best.
I know I'll raise some response, but I think the 'inner-third' is written off largely because it has been said here before, and repeated, without the conlusive evidence to support it.
Anyhow, keep up the great work. Look forward to seeing it up.
