Details
The Flashhobby H450 helicopter motor uses a 28.4mm diameter body, 38.5mm overall length, and a 3.5mm output shaft for fit checks and mounting alignment.
The Flashhobby H450 3800KV motor features a ribbed cylindrical housing with a red end cap and a protruding output shaft for helicopter builds.
The Flashhobby H450 helicopter motor comes with mounting screws, bullet connectors, and heat-shrink tubing for clean wiring.
A basic brushless setup connects the H450 motor to an ESC via three phase wires and uses a PWM lead to the receiver, with the battery powering the system.
