Part of EMAX's ECO II motor range, it is intended for demanding aerial propulsion applications and comes in four configurations: 350KV, 380KV, 420KV and 500KV. These are variants of the same 4320 motor platform, giving aircraft builders a choice of KV ratings within its stated propeller range.
The motor measures 50.6 × 68.7 mm and weighs 298 g including wires. Its construction uses a 12N14P configuration and a 6 mm bearing shaft. These dimensions and the wire-inclusive weight provide concrete parameters for planning motor installation and aircraft mass, while the 13–15 inch propeller specification defines its intended application range.
