The E160 Stack Adds 47.7g. When Is It Worth It?
Quick Answer
The SEQURE H743 V2 and E70 G2 stack is our pick for normal 4S-8S racing and freestyle builds. Choose E130 only for unusually demanding 8S loads; choose E160 when a genuine 12S heavy-lift powertrain requires it. The E160 stack weighs 79.7g, 47.7g more than SEQURE’s 32g E70 stack figure.
One Flight Controller, Three Very Different ESCs
All three stacks use the same H743 V2 flight controller: a 480MHz STM32H743, ICM-42688-P gyro, 16MB blackbox, six UARTs and eight motor outputs. It supports Betaflight, INAV and ArduPilot, with 5V/2.5A and 10V/2A BEC rails. If those are the features you need without a bundled ESC, the standalone H743 V2 is the cleaner purchase.
The decision is therefore not about processor speed. It is about voltage, physical size, mass and credible motor current. Our catalogue puts the compact E70 beside two much larger ESCs intended for high-power aircraft; treating them as simple “good, better, best” upgrades would be wrong.
| Stack | ESC input | Continuous / peak per channel | ESC size | Published stack mass |
|---|---|---|---|---|
| E70 G2 | 2-8S | 70A / 150A | 45.5 × 42.5 × 6mm | 32g |
| E130 G2 | 4-8S | 130A / 220A | 54 × 57 × 7mm | 54.7g |
| E160 G2 | 4-12S | 160A / 280A | 54 × 57 × 10mm | 79.7g |
Why We Would Stop at E70 for Most Builds
A published current ceiling is not a target. Motor, propeller, voltage, cooling and flight style determine the actual load, so size the ESC from motor test data with headroom rather than buying the largest number. Our motor, ESC and prop matching explanation covers that process.
For a conventional freestyle quad, 70A per channel is already substantial. The E70 also weighs 17.5g as an ESC, has current sensing and telemetry, and supports AM32. We would accept the larger E130 only when verified 8S motor data exceeds the E70’s sensible working margin. Read the frame drawing first: the 54 × 57mm E130 is not a normal 30mm square board even though its mounting holes are 30.5 × 30.5mm.
What the E160 Actually Buys
The E130/E160 stack listing contains two materially different options. E130 remains a 4S-8S ESC. E160 adds 12S support, 160A continuous and 280A peak current per channel, but grows to 10mm thick and 66g for the ESC alone. That is heavy-lift and cinelifter hardware, not a performance badge for a five-inch quad.
There is one wiring detail we would not improvise: the flight controller itself is rated for 4S-8S, while the E160 ESC accepts up to 12S. SEQURE’s manual says to bridge V to V+ so the ESC’s 16V BEC powers a controller that cannot take 12S directly; bridging V to BAT instead passes battery voltage. Follow the supplied diagram and verify the jumper before connecting a pack.
Our Pick
Buy E70 for racing, freestyle and most long-range quads. Buy E130 only after current data and cooling calculations justify its extra 22.7g over the E70 stack. Buy E160 for a designed 12S heavy-lift system where its extra 47.7g is already in the mass budget. Browse the wider flight-controller and electronics range, and read our AM32 flashing guide before changing firmware.
FAQ
Q: Can the H743 V2 control an X8 aircraft?
A: Yes. SEQURE specifies eight motor outputs. Check output mapping in your chosen firmware and validate every motor without propellers fitted.
Q: Do all three ESCs support AM32?
A: Yes. Current SEQURE documentation lists AM32 support for E70 G2, E130 G2 and E160 G2, alongside telemetry and current sensing.
Q: Can I power the E160 stack directly from 12S?
A: The E160 ESC can take 12S; the H743 V2 FC cannot take raw 12S. Configure the manual’s V-to-V+ 16V BEC feed rather than sending battery voltage to the FC.
