The Nighthawk-X4, X5, and X6 are EMAX’s first pure X frames with equidistant motor placement and centered mass for the ultimate in balance and agility. For ultra clean builds, our team created a custom PDB with Dual Shielded Voltage Regulators, integrated XT60 battery connector, low voltage buzzer and programmable LED strip. The built-in PDB serves as the top half of the main structural frame, eliminating the need for another carbon piece to save precious weight.  With all the components arranged towards the center, its center of gravity allows the X frame to turn in an instant. Different arm lengths make it convenient to change frame sizes...from 4” to 6”. Nighthawk-X6 (6” frame) “All-Up-Weight” is less than 490g with a 1000mah 4s battery, and can achieve high thrust to weight ratio.
