The black widow...Sold by rcareodyne at http://www.scaleflying.com/Black-Wid...SB_p_2600.html
. The way i understand it is that rcareodyne was to use these fbl controllers on their chaos 550 helis that were to come out this time last year. ( a year later and their 550 has yet to come out. ) Go figure.
The re-branded version of this fbl controller is from Hobby king the Robird g31 seen here at http://www.hobbyking.com/hobbyking/s...ss_System.html
To date i have only known of one guy using this unit, And he seems to like it.
