MicoAir 4-in-1 70A ESC (3-6S, 30.5x30.5mm)

A 4-in-1 ESC from MicoAir rated at 70 A per channel on 3–6S LiPo, on the standard 30.5 x 30.5 mm stack pattern. The current headroom suits heavy 5-inch freestyle, 7-inch long-range and larger builds where the motors pull hard for long stretches.

Key features

• 70 A per channel from a 3–6S pack (11.1–22.2 V nominal)
• 8-layer PCB with 2 oz copper to carry high current and spread heat
• Low-resistance MOSFETs (0.95 mOhm RDS(on)) for less heat under load
• Onboard current sensor output for the flight controller's current and mAh readings
• 44 x 43.5 x 5.2 mm and 15 g; ships with an XT60 power lead and an FC interconnect cable

Specifications

• Current rating: 70 A x 4
• Input voltage: 3–6S LiPo
• Mounting: 30.5 x 30.5 mm (M3 with soft mounts)
• MOSFET RDS(on): 0.95 mOhm
• PCB: 8 layers, 2 oz copper
• Dimensions: 44 x 43.5 x 5.2 mm
• Weight: 15 g
• Included: XT60 power lead, FC interconnect cable

Check that the interconnect cable's pinout matches your 30.5 mm flight controller before the first power-up, and fit a low-ESR capacitor at the battery pads, especially on 6S.
