I have had the sensor bar for several months now and the ESP for 2 years prior to that. Just like on the ESP when you flag out on mini 5th line the green/yellow power line would bunch up and on occasion tangle when let things out again. Well for some reason unknown to me Core put that stopper ball on the sensor bar to prevent the smaller caliber line from pulling through when flagging out. what happens is all that slack when the bar moves up the line bunches up and may tangle and prevent reset ing the line.

Now, here is what you do: take the stupid stopper ball off up at the Y and reconnect the line together, now it is fixed. This way when you depower all that slack line will be pulled through the line guide, the bar will be pulled up to the guide, and no more issue.

Core is very progressive, but even the ESP bar had stupid little things that needed to be modified from stock in order to make it better. The devil is in the details.

And yes, sand will jam the rotor if not knocked loose. I don't care who says it won't keep It from working, it will if your not paying attention. Otherwise the only way it is going to be a possible problem is if you are being dragged in the sand down the beach, which could happen.

that twist "Quick" release looks a bit dodgy !
