I'd recommend the HW v3* in the 6. It fits perfect in mid and rear motor configs and the wirings very tidy because of the switch. Plus the BEC wire is the exact length to run through the side channels no trimming required. Also switching to blinky mode is just a profile change. It has enough horsepower to keep all firmwares on board and data logging as well. Power turns off when u hold brake for 6 seconds, helps a lot when running back to back heats!
