BOM

I've been trying to budget the project in terms of cost and weight of the quadcopter.

I have a model in mind of a simple 24" wide X shaped design made of wood, polycarbonate and sorbothane (for vibration dampening). With that model in mind and a quick survey of what I need to propel / control the quad, I get the below.

Description	Size	Units	Weight (g)	Wratio	Price (CAD)	Pratio	Required	TWeight	Tprice

(optional) Xbee radio

Some components I've already bought and weighted, some are just approximations based on some quick web searches. I haven't locked on some components.

Still, I'm 11% under budget for weight, and 28% under budget for cost. I've excluded the cost of tools - they can always be reused for other projects. I've taken a similar commercially available kit (ELEV-8 V2 Quadcopter Kit from Parallax) as a reference. I've converted the amounts in Canadian currency (CAD).

Metric	Total	Target	Delta	%
Weight (g)	1341	1500	-159	-11%
Price (CAD)	435	600	-165	-28%
