It uses a reinforced PP material and includes two frames—one black and one transparent. The frame features a lowered profile, motor fix slots for precise alignment, and design refinements that boost thrust by 11% compared to the original Air75.\u003c\/p\u003e\u003ch2\u003eDesign improvements for better thrust and control\u003c\/h2\u003e\u003cp\u003eCo-developed with pilots, the Air75 II frame reduces arm braces from six to four and adjusts duct aerodynamics. This increases thrust by 11% over the previous generation. The structural changes also lower frame vibration when paired with Feedforward tuning, leading to smoother PID step response and crisper maneuvers.\u003c\/p\u003e\u003ch2\u003eFrame dimensions and weight details\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eWheelbase\u003c\/td\u003e\n\u003ctd\u003e75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight per frame\u003c\/td\u003e\n\u003ctd\u003e4.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePP (polypropylene) blend\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor mounting\u003c\/td\u003e\n\u003ctd\u003e3-M1.4, 6.6mm pattern\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFC mounting hole spacing\u003c\/td\u003e\n\u003ctd\u003e25.5×25.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery slot size\u003c\/td\u003e\n\u003ctd\u003e16.3×6.3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum frame dimensions\u003c\/td\u003e\n\u003ctd\u003e99.1×99.1×16.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColors included\u003c\/td\u003e\n\u003ctd\u003eBlack and transparent white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCompatible parts for building your whoop\u003c\/h2\u003e\u003cp\u003eThe frame works with Matrix 1S and Air Brushless flight controllers, 0702, 0802SE, and 1102 motors, and 40mm 2-blade or 1611 3-blade propellers.
