I was given a SirinFPV flight control board to test. This flight board is pretty awesome. Its not only a F3 flight control board with a SPI Gyro, but it also has OSD built in and to top it off there is a 200mw vTX as well! This means you can not only use the OSD to adjust PID's on the fly, but you can also use the OSD to adjust vTX channels too!

Honestly, I dont know how I could have stuffed everything into a 130mm build without it. I would have had to omit the OSD entirely, and who really cares about an OSD on a Micro 130mm build??? Well, ME! lol I really like having an OSD.

Build also consists of the MRM 4in1 20A Zeus ESC which replaces the need for a standard PDB. Neither the FCB or ESC offer 5V, so a 600ma Pololu was installed to provide 5V to the SirinFPV board. The SirinFPV board then powers the camera & receiver making it a really easy build with very minimal wiring.

Frame is a MRM Micro Scythe and I also used the TPU printed FPV camera mount to house the Micro 600TVL wide angle FPV camera they offer. I have decided to play it safe with this build, and will be using a 3S lipo with the DYS 1306-4000kv motors & HQ3030x3 props.

Because of the 4in1 ESC & the all-in-one flight control board, this entire build was way easier than it should have been. I am only concerned if one ESC should fail I am in for a full tear-down & rebuild. Same thing if the OSD or VTX should fail on the Sirin, but lets hope that doesnt happen!!
