Hi all,


I have a problem with my micro Build FLY EGG 100mm, maybe someone can help me....

I plug the battery into the ESC 4in1, everything is fine, the ESCs sound and the FC has power. I go to BF I set everything up and when I try the motors tab, each motor does the same, turns left then right and stops and emits a peeee. I'm desperate I switched from ESC to another of the same model but new, same result, I bought another King Kong 1103 7800kV engine pack, same result. I have flashed the ESC to different BLHeli verions, now I have the 16.6 Dshot. I've tried Dshot Multishot to Oneshot, each with its corresponding firmware. I have tried to change the firmware of the FC for others even from February 2017 without getting anything. Even I tested to remap motors with the resource command in CLI. I do not know what else to do. 
Could someone help me, I am desperate with my micro, it is the first micro build I do, I have already mounted two drones in 250 and 210 and I have some experience.

My build is this:
Frame: King Kong Fly Egg 100
ESC: Eachine minucube 10A 4in1
FC: Eachine Minicube F4 v1.1
Power: 2s LIPO

I have not mounted the RX/VTX/CAM/OSD yet.

Thank you very much to all!

At this point I would suspect the FC firmware. Have you tried re-flashing the same version (but fresh download) firmware yet?

The firmware for the Eachine 10A 4-in-1 ESC is BLHeli_S F-H-40 for Multicopter.

The one firmware supports OneShot, Multishot and DShot. There are not separate firmwares for each.

Check that you have the correct firmware installed. Change nothing from the defaults other than setting motor timing to 'High' and reversing the motor direction as required. Use DShot600. That way, you don't have to bother with calibration.

If the motors don't want to spin, check your soldering. Some of these small motors have motor wire all the way out and this wire is covered with a lacquer to insulate the wires. If you don't scrape it all off before soldering the wire to the ESC, there might be a connection, but it won't carry enough power to spin the motor.
