SpeedyBee F7 Mini Flight Controller Stack 3-6S 20x20mm Built-in Bluetooth Drone Stack with 35A BLHeli_S 4 in 1 ESC Support Wireless Tuning for 2-4 Inch FPV Drone

Got this mini stack after putting the F7 V3 Stack in a 5". Installed this one in the ImpulseRC Apex Micro 4" with a TBS Tracer Sixty9 VTX+RX and Foxeer Toothless 2 Camera. Motors are BrotherHobby 2004 2100kv. Love it! Supports a DJI system very simply, however I went with analog for this one - but nice to know I could change my mind in the future. Works just as well as its big brother and was super easy to wire up, install and configure. Coated the whole thing in FPV Worry Free conformal coating and chose the starlight camera so I could fly in the dark, snowy Northwest winter that I find myself in all of a sudden. Solid product from SpeedyBee.

I'm a novice at building quads but this Flight controller was pretty straight forward in its assembly and use. My only fault is the solder pads are very tiny and at 83 years of age, I'm not as shake free as I should be but if I can get it soldered without bridging any young whipper snapper can do it with ease.

for my little Micro Apex 3” clone. Solder pads are OK for a 20mm stack, and Bluetooth functionality is nice. Initially, ESC wasn’t working properly, but after flashing Bluejay, it’s all good. Gonna use the same stack with a 5” LR I’ll be building over the winter.UPDATE 1/23: A bit disappointed with this stack. Of the two I bought, one is still working fine, but the 5v regulator is fried on the other one. Next time, I guess I'll go back to a Mamba mini stack, or maybe try one of the newer Skystars F722 stacks. :/

These units are not shipping with MPU6000 gyros anymore and come locked to 3.2kHz PID loop with the BMI270 gyro. Considering the price increase and the locked gyro, I want to be able to use DSHOT600 and it is not recommended to use with a PID loop lower than 4kHz so max is DSHOT300 so it is a real bummer and waste of processing capabilities of the F7 chip to have a lower locked gyro PID! RETURNED

Bought this and put it in a little 3” diatone frame and haven’t had a problem since. It’s ran everything I’ve thrown at it with no problems. No complaints. Do keep in mind when purchasing that it’s a 20x20 and so will be a bit more difficult to work on for those less experienced with soldering like myself.

Nice 20*20 flight controller

Love that I can tune with my phone, sucks I cant update my fc unless it's through computer. I recommend if you have a computer you can connect to for updates.

Great flight controller speedy is great for ESC tuning Bluetooth connectivity for Speedy Bee app works fantastic not a total replacement for beta flight but pretty damn close I love these like controllers I bought three of them
