SpeedyBee F405 AIO Flight Controller: 40A 25.5x25.5 3-6S Bluejay FC ESC PDB Board with Wirelessly Betaflight Setting INAV for 2inch 3" 4" and Ultra-Light 5inch FPV for DJI O4 O3 AIR Unit/PRO

Speedybee makes such good products and they are almost always one of the more budget friendly options. This AIO FC is working perfectly as a replacement in my 3 inch drone I built this year

Good little aio when fully functional. I had to replace the previous board due to unreliable sbus connectivity. I’m running multiple speedybee stacks and aio’s in my fleet and they perform well. One bad apple but Amazon replaced it overnight and the replacement is all good. Not exactly convenient to have deconstruct the new quad but very pleased with the build.

good aio. good price

I'm using this in a 145 gram airframe. The 1104 motors are doing well with it. The pads can be tight... Very tight. However, the board seems undamaged by a short I created when adding components. The fault appeared by destabilizing the gyroscopes or accelerometers, causing a shifting yaw axis. Once cleared, the board operated as advertised.

Great little FC ESC combo. Only issue I've had is the negative grounding points on the board, ordered one directly thru speedybee on pre-release and one thru here. Both had same ground pad soldering issues. Have to super clean the ground points with iso and soft brush in order to get good soldering penetration and not have the solder joints pop off. Hooked directly thru betaflight, all components are good from factory, flies stable.

I have bought a few of these now. They work great and take minimal space 😁 hook ups for everything. Have been flying these since they were first released and no problems yet. They are durable and powerful. I will be getting more 😁

Works extremely well. Ran about 20 packs through with zero issues. A little heavy but worth the weight in cooling. Worth every penny.

I love the Speedybee aio its an excellent choice for very small builds and it's loaded with features and extra components.
