Ryan I think he changed the conversation. Sam said he hasn't used MK in awhile and is using the Freefly PDB and ESC's. Likely not using the MK flight controller but something like DJI or SuperX. Alternatively you could use the FF or another PDB and individual MK BL 3.0's and use a harness for the C/D I2C bus but that get's pretty messy.
Thanks Gary, I am using the power hungry board, and DJI Wookong With KDE escs and motors. MK is very different from my setup. Sorry if I Confused anyone.
Nice. I am real happy with the way my Hex coax runs (still testing) with 10k's the flat is amazing with a pair avg flight times are in the 24-26 minute time with M5 and A7s.
