I'm shooting some camera copters in a near future and my clients already gave me some insights on what they want. All is well except for one thing.. they want almost exact replica of this picture

TOO LARGE!

and I am to figure it out how to make a black object (for this example, the body of the copter) so visible, with having a black background/canvas. I only have 1 430EX II to work with, but I'm thinking it's just flash + raw + lightroom and/or photoshop + numerous shots (with different flash settings) to see which works best.

Any ideas and tips?

Think in terms of edge lighting. (Your image isn't showing yet.) The histogram is going to be difficult to use - do you have a flashmeter, would help but not essential.

Even with one light, you could use a mirror opposite and feather the light on the subject while the Speedlite is aimed & zoomed so that the reflected light is equally strong. You could probably get ratios from nearly 1 : 1 to 1 : 8 experimenting along those lines.

A challenge, but fun!

This had a white diffuser cam L and a silver reflector cam R - the 580ExII was well off to cam L zoomed to 105mm & aimed such that direct light could reach the reflector but obly diffused light reached the subject from cam L.

I'm no commercial or studio guy however I think this is a (I may have the term wrong) stacked shot. Multiple shots with the light source moved around then blinded together in PP.
Check this tutorial out about photo stacking for light painters. I think the same technique was used for your example.

...good luck

I do not have a flashmeter.

I was thinking about stacked photos myself, but I don't know. Will check the link. Any ideas are still welcome.

The ability to place light sources and reflectors so that selected SURFACES & EDGES of the subject item reflect the light from those sources/reflectors is the key skill to understand, to achieve the definition to the subject without a tonal difference between the background lighting and subject lighting.

That is precisely how OceanRipple achieved his posted result. Note the size of the source/reflectors, along with precise placement of them, is very important to achieve the visible reflections seen along edges and surfaces of the subject item.

The use of stacking might or might not have been included in combination with above.

Technically, the background of the image you posted is not black. That alone goes a long way to providing separation for the copter. Since you only have one flash I would suggest doing the same. OceanRipple's set up with the background a little closer, and not a material that will either eat up or reflect too much light, will likely work fine.

Edit: I seriously doubt the image to be copied had a lot (or any) post work done. It's really pretty basic lighting set up.
