The second-generation Air75 brushless whoop frame, redesigned with pilot input. Arm braces are cut from six to four and the duct and connecting structure are reworked, making it about 10% lighter than the original Air75 frame (4.00g) and giving 11% more thrust. The connecting arms damp frame vibration, and with Feedforward tuning BETAFPV reports a near-ideal PID step response. The optimised PP blend absorbs crash impacts.
