Well, here's the first photo of my quadcopter.

Weighing in at 590g as it sits, with a span of 25".  I plan on adding some litening holes in the body plates and landing gear to reduce the weight a little.

Cutting the bolts will lose a few grams, but this is just a dry fit, so nothing's done as of yet with any permenance.

I plan on powering it with seperate batteries for eletronics and flight, the motors will be 4 Turnigy  TR35-48-B, 900Kv motors with Master airscrew 11*7 , 3 blade props. powered by a Zippy flightmax 5000mAh 5S1P 25C battery.

This will have telemetry, video, sonar, gps, magneto, APM with all the bells and whistles. Hopefully I willl be able to get some decent flight time out of it.

Would it be better to go with 2 blade props, or what I have spec'd? I'm not looking for acrobatics, just long stable flight.

I will update with pics of progress as things start to evolve more.
