A quick build is a sig wonder. I built mine about 8 years ago with a dissapointing speed 600 power system , put it away for 7 or so years, changed it to a cheap 25 amp brushless setup thinking it might be okay as a park flyer, now it eats up too much sky for any of the local parks around here. Its easy, different, fairly fast, and handy when I dont feel like getting out all the glow stuff.
