ESCs – Aircraft

Speed controllers built for props and EDF fans, with a BEC for the receiver and a brake for folding props. Spektrum's Avian Smart range (6A to 160A HV) reports telemetry to a Smart-equipped radio; Castle's Phoenix Edge and Talon are the programmable premium option; Hobbywing covers budget to high-end with Skywalker, FlyFun and Platinum; Dualsky's XC Lite and Summit series are the club-standard value ESCs.

Size the ESC 20 per cent above the motor's maximum current and check the cell count — the 3S–6S sweet spot covers most sport models, HV ESCs take 8S and up. Programming cards and Castle Link are cross-listed here from the Switches, BECs & Programmers shelf.
