**i havent found any reviews on rcgroups about this FC, yeah its F3 but should be good for me.*** i hope i have a positive experience with it.

Just got one of these in yesterday finally. i went with it bc it has 3a 5v onboard, F3 with lot of accessable pads, Im gonna run it with a xsr-m, F3 should make the telemetry a bit less of a headache hopefully. Im putting it in my GepRC Sparrow frame - got my replacement arms the other day. I also got a Runcam Sparrow micro 16x9 fpv cam to throw in the mix. Waiting on DTX03 from Banggood US warehouse, should arrive any day now. why is their US warehouse shipping running so slow ?

Got it wired mostly last night. Im using a Super Colony 20a 4in1 esc from readytoflyquads , which has vbat output via it's mini-connector, had to depin one end of esc's connector wire to a 6pin to connect with the F3 nano, which will take in vbat - which is pretty convenient for my purposes.

I like the sparrow frame but it broke almost right away which was a major bummer. In hindsight i wish i would have bought an Airblade eclair 3in (i like the DTX03 pod you can add to the airblade eclair), but oh well. next time.

Currently got some 1407 3200kv RCX motors and dalprop 3in triblade bullnose props setup on it.

Pics soon.

Any issues with this FC? I am thinking about picking one up for my 2" quad.
I have this FC both the old and new version:
First one the LED function didn't work and also got this error intermittently FAILURE_MISSING_ACC: Accelerometer/gyro sensor is missing.
Second one (the new version) the LED works now but still get the FAILURE_MISSING_ACC: Accelerometer/gyro sensor is missing error randomly.
Here is a video of that issue:
Banggood FC Issue (0 min 18 sec)

Very frustrating. All on 3S with a load on the BEC of about 380maH. Might just be the on board BEC that isn't engineered all that well.
Have you had any issues with the board in this thread? Does the LED work, any issues with arming, gyro/accelerometer issues, etc.?
Hope it's working out. I need another option.

How to power this board?

Hello, I just received one of these FCs (Omnibus F3 NANO STM32F303 2-4S Flight Controller 20*20mm 3.7g Built-in 5V 3A BEC OSD).
How do you power the board? Through the B+ and B- pads next to the ESC connector? I will be running my VTX voltage at 5V.
I will also be running this quad on 3S.
Please let me know. Thank you, Chrys Burge

Using this board now on my 2". No problems at all. Not running LED on my build though so I can't comment on that.

This board failed during the build process. QC may not be the best...
I can no longer get it to connect to the Configurator.
