Supports versatile drone protocols and connectivity
Handles 2-6S input with 55A constant current
The iFlight BLITZ F7 Stack (E55 4-IN-1 ESC) is a sophisticated component designed for enhancing the performance and reliability of drones, particularly those ranging from 7 to 10 inches. This stack features an improved circuit design that incorporates superior components, resulting in reduced electrical noise. It is equipped with a DJI HD VTX Connector, which facilitates a plug-and-play setup, eliminating the need for soldering. Additionally, the flight controller includes indicator LEDs that assist in visual debugging, and an LC filter is integrated to further enhance performance.
The flight controller is powered by an STM32 F722 MCU and features the ICM42688 gyroscope, which was updated on January 11, 2024. It also includes a DPS310 barometer and an AT7456E OSD chip, with a substantial 32MB of Blackbox flash memory. The controller supports six UARTs, allowing for versatile connectivity options, including motor outputs and I2C serial communication. It is compatible with Smartaudio and IRC Tramp VTX protocols and includes a built-in LED controller and beeper pad.
The ESC component of the stack supports a 2-6S lipo input and is driven by a G071 MCU. It is capable of handling a constant current of 55 Amps and a burst current of 65 Amps. The ESC supports various protocols such as DShot150, DShot300, DShot600, MultiShot, and OneShot, providing flexibility for different drone configurations. The stack's design includes a current sensor, although it does not feature a BEC.
Note: When using this ESC on a 7-10 inch drone, it is advisable to add an additional capacitor to prevent overloading the onboard capacitor of the ESC.

A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
