4 in 1 ESC 45A Electronic Speed Controller for FPV RC Drone with Double Hole Spacing Review (2026)

A no frills 4 in 1 ESC for common frame patterns

This board combines four electronic speed controllers onto one plate rated for 45A continuous current with a 50A instantaneous peak, and it supports dual mounting hole spacing at approximately 20x20mm and 30.5x30.5mm with M4 apertures, according to the manufacturer's listing on Amazon. That dual spacing is a genuinely useful feature since FPV frames and flight controllers are not standardized on a single stack size, so having both common patterns built into one board means a builder does not need to hunt for an adapter or a specifically sized ESC to match their frame. At roughly 44 by 43mm and 46 grams, it fits comfortably into a typical mid size freestyle or racing stack.

Firmware and protocol support

The board ships with BLHeliSuite firmware version BL16.7 and supports the common protocol range a builder is likely to need, including DSHOT150, 300 and 600 along with PWM, Oneshot125, Oneshot42 and Multishot, per the listing. That protocol coverage means it should pair without issue with most current flight controllers running Betaflight or similar firmware, since DSHOT in particular has become the default choice for many builders due to its reliability over analog PWM signaling. Builders planning a fresh build around a modern flight controller should have no trouble getting this ESC talking to it during setup, and updating firmware later through BLHeliSuite stays a straightforward, well documented process for anyone comfortable with basic flashing tools.

What is missing compared with pricier rivals

Unlike the closely related 45A ESC in this same lineup that adds damped light braking and regenerative braking for sharper throttle response, this board keeps things simpler without those extra modes, which in turn means it also runs cooler under sustained load since it is not working the motor as actively between throttle inputs. The listing does not specify a working voltage range or brand name, both details worth confirming directly with the seller or checking community reviews before committing to a build, since an unlisted voltage rating leaves some uncertainty about exact battery cell compatibility. Buyers planning a 6S build in particular should verify voltage tolerance before ordering.

How it compares with other ESCs in this guide

This board sits toward the lower half of the ESC comparison in this guide, ranking below the iFlight SucceX-E, SPARKHOBBY 45/60A and the closely related damped light version of essentially the same board. Against that damped light sibling specifically, this version is the simpler, likely less expensive option for builders who do not need the sharper braking feel and would rather have a cooler running, straightforward ESC. Compared with the established iFlight and SPARKHOBBY options, this board offers similar core specs with less brand assurance and a thinner published spec sheet.

Verdict and who should pick something else

This ESC suits a builder who wants a straightforward 45A 4 in 1 board with flexible mounting options and does not need damped braking or a big name brand behind it, particularly for a budget build where dual hole spacing solves a real fitment problem. Builders wanting sharper throttle response should look at the damped light version of this same board instead, and anyone who wants full confidence in voltage rating and brand support before a serious build should consider the higher ranked iFlight or SPARKHOBBY options in this same guide. For a simple budget stack replacement, it does the core job without surprises.
