$59.99 for a Bluetooth 35A Stack? That’s ridiculous!
Utilizing an upgraded F405 flight controller chip with better performance than the F411, it features a built-in Bluetooth chip for seamless wireless Betaflight tuning. The board comes with a 4-level battery voltage display, built-in barometer, and supports connectivity to all DJI Air Units. It offers 4 available UART ports, and a dual BEC setup with 5V 2A and 9V 3A outputs.
35A 4-in-1 BLHeliS Mini ESC: This ESC provides four synchronized outputs with a continuous current of 35A, delivering strong power to drive all 2-4 inch and lightweight 5-inch quadcopters via 4-6S battery. Equipped with a TVS transient suppression diode onboard, it better absorbs surge voltage, providing enhanced protection for the ESC.
Tune Flight controller and ESC wirelessly!
Power the quad, connect the SpeedyBee app via Bluetooth, configure the UART Ports,PID,OSD and every other settings on this flight controller. Also, every parameter of the BLHeli_S ESC in this stack can be set via the app.
With this Bluetooth stack, even micro drones become easy to tune—no need to worry about the hassle of inserting USB cables into the flight controller. Simply tune your drone wirelessly through the App, and say goodbye to wires and worries!
Powerful Real 35A 4-in-1 ESC!
6-layer 2oz PCB plus optimized circuit design equals stable and strong current output. The four-channel continuous 140A output can reach 30 seconds*.
The use of Japanese TDK filtering SMT capacitors and the onboard TVS protective diode, further enhances your flight experience, providing a seamless and reliable performance. The stack underwent rigorous pressure testing with various 5-inch freestyle and racing drones, confirming its powerful capability to effortlessly drive any 2-4 inch and lightweight 5-inch drones.
Clean Gyroscope Power Supply, Smoother Flight
Equipped with the renowned brand MaxLinear's LDO power supply chip, the gyroscope receives independent power, boosting surge protection capacity by 320%. Additionally, built with a 100uF ultra-large filtering tantalum capacitor, guarding the gyroscope's data from interference caused by the power source. Each posture and movement during flight receives precise responsiveness, allowing you to fully experience the pure beauty of flying!
Forgot your LiPo checker? Just look at the FC!
On the side of the flight controller, you will find a 4-level battery capacity indicator. As soon as you connect the battery, you can instantly see the battery level, saving you the hassle of needing to put on goggles to check the battery status.
Change motor directions wirelessly!
Are you still using a computer to change motor directions? With this stack, when you finish your build, connect to the SpeedyBee app, change the motor directions just in a few simple steps*. Then take off.
* To use this feature, go to the App > Motors > Motor Direction Settings.
Support DJI Digital Video Transmitter
The flight controller has two independent 9V 3A BEC and 5V 2A BEC, supports various analog image transmissions above 5V, and also supports DJI O3 Air Unit/Link / Vista/Air Unit V1
M2 or M3? Why not both?
Have you ever experienced that the stack holes of your frame did not fit the stack you got? This stack is perfectly compatible with M2/M3 screws. What’s more, two sets of M2 and M3 screws + silicone grommets are included in the package!
TVS Protective Diode + 470uF Low-ESR Capacitor = Upgraded ESC Protection
The ESC is built with TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. We also provide a Rubycon 470uF Low-ESR capacitor, ensuring clean data from the gyro to the FC.

Polished Everyday Crossbody, Though Priced Like a Designer-Branded Bag
Color: Vanilla/Acorn
This crossbody bag has a clean, classic look that works well for everyday use, errands, travel, or casual outfits where you want something more polished than a basic purse. The north-south shape gives it a slim profile, so it does not feel overly bulky, but it still has enough room for daily essentials like a phone, wallet, keys, small cosmetics, cards, and other small items. The zipper closure is a practical feature because it keeps everything more secure than an open-top bag, especially when walking around, shopping, or traveling. The front and back zippered pockets are also useful for items you want quick access to, like a phone, receipt, lip balm, or transit card. I like that the layout keeps the bag organized without making it feel complicated. The material is mostly PVC with some polyester and polyurethane, so it has more of a coated designer-bag feel rather than soft genuine leather. That makes it easier to wipe clean and more resistant to everyday marks, but buyers should know they are paying more for the brand/style than for leather construction. The bag feels structured and presentable, but it may not have the same long-term aging or softness as a real leather crossbody. For comfort, the crossbody style is convenient because it keeps your hands free and distributes weight better than carrying a small handbag by hand. It is best for people who want a stylish everyday bag, not someone looking for a large tote or something that can carry bulky items. For pricing, similar branded crossbody bags usually range from about $80–$200, depending on the brand, size, material, and whether it is leather or coated canvas/PVC. At around $180, this is on the premium side for a PVC-blend crossbody, but it is fairly typical for the Michael Kors price range. Overall, it feels worth considering if you like the style and brand name, but value-focused buyers may want to compare sale prices or color options before paying full price.
