cplager - Thanks, although the option of buying used is not available to me. Seems like even the cheapest tadpoles are insanely pricey and inspite of that one hardly seems to hear good words for them.

StephenH - Thank you for those links. Looks like a full fairing is really not worth the trouble, then...

fietsbob - I had similar thoughts about Coroplast...until I saw this! Damn! @_@ http://www.instructables.com/id/Facet-V1-Velomobile/
One could add more facets to that design to make smoother 'curves', although that would complicate fabrication even further...although yeah, it does look like a stealth fighter )
I agree with you on hotbike's fairing, too...looks kind of underwhelming :S

I guess I will have to bite the bullet and set about making a tadpole trike, then. Something like this but with front suspension. I guess these could be helpful in that journey, as well -

And eventually topping that off with a Coroplast, or even blown acrylic, shell.

I'll not be making it myself (no workshop, no experience in welding and cutting etc, no equipment, no mechanical engineering experience or knowledge), but will instead be giving it out to a workshop to work on, and will oversee the whole fabrication process. The skills of the folks at the workshops in my country may or may not be very good...but what's certain is that they've never seen a recumbent trike all their lives (in fact, mine might be the first in the country). Think it'll work out?
