Huge pads to solder. Easy to setup in Betaflight. Works with the SpeedyBee app. Very convenient. So far so good.

I like these a lot, I used to use the Mamba's but you could tell them apart, so when I got speedy bee, I really liked the digital adjusting and programing but I also liked on they don heat up as fast either, they stay cooler. Easy to read easy to solder and install.

ESC works great and has a ton of awesome features. ESC smoked a MOSFET on an actual first flight on motor 2. I am really upset since I have plenty experience and it just FAILED and SMOKED instantly. I tested it plenty in Betaflight before my test flight for 50% input, and set up my Transmitter for 50% input, and setup my PID settings fpr 50% input. Did not want it flying away. I would understand my error if it was the motor that smoked, but the fact the ESC MOSFET died is the problem, and I blame bad manufacturing. I bought another one hoping I just got a bad unit. I am contacting seller and MFG for input.

Installed in a 5" quad and loving it.I have installed and tested both Betaflight (4.4.x) and iNav (6.x) Firmware with no issues.I never knew how much I would rely on the Bluetooth capability and the ability to adjust FC parameters/settings at the field. I doubt I will even consider another FC (in any vehicle) without this very useful feature.Kinda pricey but I have been very happy with this device.

****Updated Feb 2023****I have now put three of these in fpv drone builds. Simply the only stack you need if you're looking for 30x30. Rock solid and the built in Bluetooth is so great. And seriously, the battery voltage led meter might seem hokey, but it has turned out to be incredibly convenient! I have also used the SB F7 Mini Stack in smaller drones and it is equally a great performer.Don't hesitate to grab one of these. You really can't go wrong with it. I've used the plugs and have direct soldered and it's easy to work on.Placement and orientation can be tricky if you use the included capacitor - it's giant haha! I have used the 1500 that SpeedyBee includes, but I have also swapped it out for a more manageable 1000 and it's not any different running big 6s batteries to large motors. Depends a lot on your frame. The Armattan Beaver fits the larger cap great with the battery pads oriented to the front. The Ummagawd Demibot required that smaller capacity to fit the way I wanted to install it. You can definitely turn it any direction you would like and just configure in BF or whatever flight firmware you're running.I've used T-motor, Skystars, and BetaFPV stacks and they work great too - however this SpeedyBee stack seems to have all of their positive attributes plus a little of its own magic. So for the time being, I'm sticking with this stack for all my larger drone builds.*****************Used this FC + ESC stack on a 5" freestyle build. Second time I have used this particular SpeedyBee product. Also have built a couple of drones using their F7 Mini stack. Both have proven to be rock solid. No problems, easy to wire up and configure, solid performance. I chose this stack because I live in the Upper Left USA where it is dark/snowy/rainy for 6 mos of the year and wanted to build a waterproof drone. The SpeedyBee stacks supporting Bluetooth config via their mobile app meant being able to waterproof the USB port to seal her up nice. Can still change any setting and update both FC and ESC firmware from the app over bluetooth or wifi. Killer! Love this thing and it looks amazing installed. The plugs are nice features if you are looking to build a drone simply without a lot of soldering. I direct soldered the camera, vtx/rx, and buzzer and the pads are nice and big and easy to work with. The battery meter onboard is a nice touch as well, super easy to just glance down and get an approx battery percentage.The flight performance is incredible - I have zero issues with this stack. I just applied the Supafly 5" Betaflight Preset tune with amazing results, however if you are looking to get down and dirty tuning your drone, this thing packs an insane 500MB of onboard Blackbox flash to nerd out on your graphs and stuff ;)Can't recommend this (or the F7 Mini stack if you are looking for 20x20) enough. This combination of components with the F7 V3 at the center was a great choice and I'm glad I went with this stack.Frame: Ummagawd (Botgrinder) Demibot coated in Krylon Glitter Blast Citrus Dream paintFC+ESC: SpeedyBee F7 V3 + 50A (this product)VTX: TBS Sixty9 Tracer w/SpeedyBee 5.8GHz antennaCamera: Foxeer T-RexMotors: T-Motor Slatts 2306.3 1700kv motors with Pyro drone LED race wires in redBuzzer: Vifly Finder 2Prints from Brain3DRadio: Radiomaster TX12 + TBS Tracer Micro TX
