well greg covey figured it out. jeti opto esc require power from the rx and the lipos. I replaced the y harness with a intact one and plugged it all in. the esc beeped and they ran nothing got hot or warm. im running 6v 3000mah through the rx and 8s 5000ma for the lipos. Greg said only the optis work like this. I have some phoenix 80 amp escs and you must cut the red wire in the y harness. or boom
