LRP esc's come with a 25 cent switch. We had numerous shut down & intermittent stop & go's until we tried a better switch. You can just bypass the switch to test it. This goes all the way back to brushed esc's by LRP . That has been the only thing I had a problem with. The little blue switch enclosure will get filled with dirt & at the time I was only running on asphalt.
