DarwinFPV F411 3-4S 30A Stack is currently the cheapest stack in the FPV world, designed to reduce the budget of entry-level FPV drone as much as possible. At the same time, we have also filled the flight control and ESC with glue, which greatly reduces the risk of damage to components caused by frequent blow-ups by novices.
In a word, if you want to assemble the stack by yourself, DarwinFPV F411 3-4S 30A stack is the most cost-effective one , none of them!
Features：
Compared with traditional stacks, we have treated the DarwinFPV 3-6S F411 3-4S 30A stack with glue to protect it, which greatly reduces the risk of damage to the stack due to contact with metal particles, fine sand and gravel, weeds or dewdrops, etc.
DarwinFPV 3-6S F411 3-4S 30A stack has built-in barometer and SD card slot, and reserves rich interfaces resource, which meet the needs of lightweight flight.
The FC integrates LC filter, which greatly reduces the VTX interference caused by system voltage changes when the drone accelerates and decelerates, and greatly improves the image stability.
Attention!!!Because the black box function of the target firmware "DARWINF411" is currently not compatible with Btaflight 4.3.0 and 4.3.1 (the black box function is expected to be added to the official version 4.3.2) If you need to use the black box urgently, please upgrade to the 4.4.0 development version or downgrade to 4.3.0_RC3 and below firmware version.

I wanted something that was packable and easy to take with. Got tired of needing to pack a large radio, neck straps, and all of the needed padding to just fly my whoops when traveling. This radio is so much easier to throw in a bag and fly with. Coming from a Taranis X9D plus, the pocket is a lot lighter and easier to carry. Gimbals feel good and it’s comfortable when holding. It’s the first small radio I tried that I was able to feel comfortable with. Compared to Zorro and TX12, the Pocket feels a lot more balanced. Highly recommended as a travel or only radio if you want something light and easy to carry.
Some downsides:
1. Arming/disarming takes a bit to get used to since there are not traditional switches.
2. Even though there are 5 position switches for the trims, you can’t use the center press as a switch like Jumper
3. The case is glossy, I wish it was more textured like DJI radios for better grip.
4. The speaker makes a buzzing sound when powered on and sometimes switching things in menus.
Otherwise great radio that’s easy to fly and live with.
I flew drones yrs ago. I dabbled in all types of drones from tiny whoops to 4 inch freestyle/acro quads to cine dji. Good beginner starter bundle. Definitely worth the $.
