OK I know I maybe jumping the gun here but how about "BRUSHLESS" for this copter? I have a Brushless Mini-T and that thing is everything and more that I could possible want it to be. So my question would be what's a good system to put into this copter? any and all suggestions are appreciated. with weblinks will be helpful as well as pictures. I'm just not sure what is worth putting into this copter. I plan on using it to be my trainer for awhile, and then upgrading to a T-Rex 450 or something similar in about 6 months or so. But I want maximun efficiency as well as performance. I already have a Li-po installed on my stock setup.

Or please list the most important upgades in order as to how you would do them. or which are most important to you.
