This quad started life as a re-frame for my babyhawk. After that fail this frame has had three different sets of motors and finally settled with the Rcx 1304's and Aikon esc's. The X3 112 is a great budget frame, I have crashed this thing HARD multiple of times and it just shrugs it off. The Rcx motors have surprised me with the crashes they have survived and are still smooth as the first flight.
