Frame was designed by Dave C FPV and cut in 3mm carbon by Cnc Madness. I tired the DYS 1404 6000kv motors at first and they were lacking the efficacy I was looking for. Then I down graded to the DYS 1404 4300kv and couldn't be more happier. I can get 7min of flight time cruising and a decent pace and it still packs plenty of punch on 650 3s
