I was inspired to build a screaming fast Projeti after reading through a build log entry by numb_thumb, his build log can be found here

Some background on the Projeti - it's a "delta wing", 1-piece molded EPS (expanded polystyrene foam) airframe, and can be purchased at hobby-lobby.com for around $110. There are a wide variety of power systems that would work well in this wing - it could easily be built as a slow, docile park flyer, or a screaming ballistic rocket (what I'm attempting to do ). The Projeti kit includes servo connection hardware, a thin plastic canopy, a plastic motor mount (not suitable for powerful builds), and a large set of decals for sprucing up its looks.

I'll start with my motor choice. I wanted something that could feasibly top the Mega 16/15/3 power set up on 5S, built by numb_thumb. I initially jumped to conclusion and assumed that a hotter Mega wind (i.e. 1 or 2 turn) might get me there, but the increased power consumption just wouldn't be worth it. After researching the power systems forum (http://www.rcgroups.com/power-systems-13/ ), I decided on an ARC inrunner 1.5 turn motor (the 28-47-1.5 turn ARC), sold by LightFlightRC.com. The link to the specific motor page is here . LightFlightRC also has their own RCGroups thread which is VERY useful for reading up on their ARC power systems. I highly recommend reading through the following thread in order to become acquainted with ARC motors...
