4 in 1 45A ESC 2-6S with Double Hole Spacing RC Drone Quadcopter Electronic Speed Controller Review (2026)

Updated September 14, 2026 · Research-based review

Our verdict

This generic 4 in 1 45A ESC covers the 2 to 6S voltage range most freestyle and racing quads use, with double hole spacing for flexible frame mounting. It fits builders on a budget assembling their own stack, but as an unbranded part, documentation and firmware support are thinner than named ESC brands.

A 4 in 1 45A ESC for 2-6S batteries with double hole spacing, an electronic speed controller for quadcopter builds.

Price range: $ (Budget)

What we liked

  • + 2-6S support covers most freestyle and racing batteries
  • + Double hole spacing gives flexible mounting in different frames
  • + 45A rating leaves headroom for typical motor current draw

Trade-offs

  • - Generic ESC, so firmware and support documentation may be thin
  • - No mention of current sensor or telemetry features

Who this ESC is for

This 4 in 1 ESC is built for pilots assembling a custom FPV quad from separate components rather than buying a pre-built drone, since it needs to be paired with a matching flight controller and frame during a build. According to the Amazon listing, it supports 2 to 6S battery voltage and is rated for 45A continuous current, which covers the range used by most 5 inch freestyle and racing setups. The double hole spacing design means it physically fits frames built around either the 20mm or 30.5mm standard mounting patterns common in the hobby. Buyers who want a plug and play ready to fly drone rather than a build component should look elsewhere entirely.

Specs and design in plain English

The product listing states a 45A rating across a 2 to 6S input range, packaged as a single 4 in 1 board combining all four motor ESCs into one unit rather than four separate modules, which simplifies wiring in a build. Double hole spacing on a 4 in 1 ESC means the mounting holes accommodate more than one common frame hole pattern, giving builders flexibility when matching the ESC to whichever frame they already own rather than needing an exact match. As with most 4 in 1 ESCs in this class, it is designed to sit in the middle of a stack between the frame and flight controller, with motor wires soldered to the pads along each edge.

Building and flying with it

Installation follows the standard 4 in 1 ESC process: mount it using the double hole spacing pattern that matches your frame, solder each motor's three wires to the correct pads, then connect the signal harness up to the flight controller before configuring firmware settings through the appropriate ESC configurator software. Because this is a generic, unbranded listing, the exact firmware version and configurator compatibility are not detailed in the product listing itself, so builders should be prepared to identify the firmware once the ESC is flashed or connected, which is a common extra step with budget unbranded electronics compared with named brand ESCs that document this clearly upfront.

Trade-offs and how it compares

Against the iFlight SucceX-E 45A V2, a well documented BLHeli_S ESC from an established brand with clear firmware support, this generic 45A unit competes mainly on price rather than documentation or community track record. Compared with the SPARKHOBBY 45/60A 4in1 ESC, which lists specific firmware and chip details in its own product materials, this listing provides less upfront technical detail, making it harder to judge exact performance before purchase. The core trade-off across generic ESCs like this one is that the lower price comes with thinner documentation, so builders may need to rely on community forums or trial and error rather than manufacturer support if something goes wrong.

Verdict and who should pick something else

For budget conscious builders who mainly need a 45A, 2 to 6S 4 in 1 ESC with flexible double hole mounting and are comfortable troubleshooting firmware without detailed manufacturer documentation, this is a reasonable low cost option for a custom build. Builders who want clear published specs, dedicated firmware support and a stronger community track record should choose a named brand ESC like iFlight or SPARKHOBBY instead, even at a slightly higher price. Anyone assembling their first quad from scratch, without prior ESC flashing experience, may also find a better documented brand name part easier to get running smoothly on the first attempt.

Frequently asked questions

What voltage range does this ESC support?

It is listed for 2 to 6S LiPo batteries, covering the range used by most current freestyle and racing FPV builds.

What does double hole spacing mean?

It means the ESC's mounting holes are designed to fit more than one common frame hole pattern, giving builders flexibility when matching it to different frames.

Does it include documentation on firmware version?

The listing itself does not detail a specific firmware version, so builders should expect to identify or confirm firmware once the ESC is connected and flashed.
