EDITHFPV Ironflame 45A 3-8S 4-in-1 ESC (8-Bit)

The Ironflame is a 45A 4-in-1 ESC from Indian brand EDITHFPV, built around the 8-bit EFM8BB2 MCU and a 6288Q gate driver. Its 3S to 8S input range covers 5-inch freestyle quads through high-voltage long-range and UAV builds that run 7S or 8S packs.

Key features

• 45 A continuous and 50 A burst per channel.
• Accepts 3S to 8S LiPo, 11.1 V up to 33.6 V at full charge.
• Ships with BLHeli_S firmware (JH70 target).
• Low-ESR input capacitor, premium MOSFETs and an integrated heatsink for thermal headroom under sustained load.
• Oversized motor pads take thick motor wires on high-current builds.
• Both XT60 and XT90 power connectors are included, so you can match the lead to your pack.
