I reduced the weight as much as possible on this build while tunning it for maximum stability in extreme wash out conditions. Whoops are notorious for yaw and roll washout on dives. This tune is 100% stable on 3S 300mAh packs and lighter. Notice the flight controller is NOT stock. The BetaFPV F4 2-4S AIO Brushless V2 flight controller is harder to find now, but lighter than the V3.
