I took my sons summit out for some daddy fun in normal mode(we have been driving it in training mode) and I noticed sometimes when I pull the trigger, it doesn't go forward, the 2nd pull it goes. just wondering if this is some type of protection feature or whatever. It doesn't seem like there is a problem with the esc as probably 70-80% of the time it goes fine. I haven't experienced this with my other esc's so just wondering if it is the beginning of a failing esc or if its normal.
