AM90 8.5KV Heavy-Lift Power System Kit is a matched propulsion package for heavy-lift multirotors and VTOL aircraft. The official MAD specification lists an AM90 motor, a SineSic 120A Pro ESC, and 73×29 or 72×25 propeller options. The kit is rated at 90 kg recommended thrust per rotor, with maximum thrust listed at 177.1 kg, and is specified for 96S LiPo operation.
The motor measures 196.8×130 mm and weighs 9.4 kg. It uses a 25 mm shaft, 200 mm extended enamel-wire lead, D75 M8×6 and D50 M6×6 propeller mounting holes, and an 80 mm M6×6 motor mounting pattern. The matched ESC is listed at 212.5×120×68 mm and 2,516 g, with 120A continuous output, 240A peak output for 10 seconds, IPX7 protection and dual CAN 2.0B communication. The system operating range is listed as −20°C to 50°C. Confirm cooling, battery voltage, wiring, propeller clearance and flight-control settings before testing.
Select CW or CCW to match the airframe, then choose 72×25 or 73×29 according to the verified aircraft clearance and motor load. Kit A includes a PT1000 temperature sensor. Kit B adds an encoder for propeller position locking and requires compatible ESC firmware.
