Cutting off the bullet connectors, soldering, using heat shrink tubing is much faster and neater. Wires end up long the way the SunnySkys ship. Having done both methods I see no big reason to mess with bullet connectors on this quad. Either way when done you must power up the quad, bind the transmitter, and check motor rotation using the upper shell arrow as a guide. On mine 34 were spinning the wrong direction. I had to go outside so it would bind with a GPS lock. Switch any two of the three wires to change motor direction. Then heat shrink whether using bullet connectors or not.
