I have a hobbywing v3.1 that seems to be getting hotter than normal. I dont remember making any huge changes in settings since this happened. I noticed because power seemed to cut out when off and on the throttle a lot. On and off the throttle I seem to loose power like every 20th time. Its not consistent and if I let of the trigger the throttle comes back on the next press. While looking into this I noticed the front of the esc(opposite side of wire connections) it was pretty hot , but my guess would be not more than 100 degrees. Any ideas on what to start looking into. All the connections "look" solid.
sounds like it could be a sensor wire. try a different senor wire. This could make it run hotter too as its basically misfiring when you have a bad wire.
