Don’t know if this the right thread to ask but since most use 1S esc’s for 1/12th this might be a good place.

Was practicing some Mod12 with an HW 1S Pro speedo and HW 3.5T. Around 15 laps in the boost became inconsistent. On the back straight it wouldn’t kick-in. Then maybe a lap or two later it would kick back in. Also, no fan on speedo. It was warm and could hold my finger on it for 5-10 secs. Any thoughts on what might be happening?
