The Vortex AM32 20A Nano is a single ESC for compact RC power systems. Its specification combines 2–6S input, a 20A continuous rating, a 5V BEC and a supplied XT30 power lead. It is relevant when the project needs a small individual motor controller, with the final choice grounded in the actual motor and load.

Use installed weight for a compact-build comparison
The 2.6g figure is explicitly for the ESC board. Include the capacitor, power and motor wiring, signal lead and mounting arrangement when comparing complete installations. A bare-board number can help identify a component; it cannot describe the mass of the finished aircraft.
The package lists a 35V 470µF capacitor alongside the leads. Plan space for those supplied parts and for their strain relief. A layout that is compact on paper still needs room for connectors, cable bends and access when a motor or ESC needs service.
Choose from the load rather than the aircraft label
OddityRC lists applications including mini fixed-wing aircraft, mini FPV quads and RC conversions. Check the complete motor and propeller or drivetrain combination before treating one of those descriptions as a fit. Size labels are useful for browsing, but they do not establish electrical demand.
Separate 20A continuous from the 30A ten-second burst rating. Include the likely sustained operating condition and cooling in the evaluation. In a multirotor, a single ESC controls one motor, so quantity and power distribution remain part of the design.
Make the small BEC part of the plan
The 5V 1A output can be considered for compatible electronics within its stated capability. Add up the actual peripheral demand and check the required voltage. An ESC supply range of 2–6S does not mean a receiver or sensor should be connected directly to that battery voltage.
AM32 supplies a configuration ecosystem described in the official project. Preserve the exact hardware target and existing settings when planning changes. For a first build, a clear wiring record and a known working configuration are more useful than copying an unrelated preset.
Before you choose
- Compare complete installed weight and space.
- Match the continuous load and the correct command protocol.
- Keep the 5V BEC budget separate from motor current.
Frequently asked questions
Does 2.6g include the capacitor and wiring?
No. The page labels that figure as ESC-board-only weight.
Can I use the 30A value for sustained demand?
The product lists 30A for ten seconds and 20A continuous. Plan using the applicable condition.
Will it connect directly to PM90?
The supplied lead is XT30 and PM90 uses XT60. A correctly rated, correctly polarised connection or adapter is needed for a compatible test.
