I've been running my Sv for some time now and didn't have any problems til' just the other day.

The boat completely cut out in the middle of the pond. -let the wind bring it it- put new batts and it was fine and ran strong the whole pack.

Today I took it out and it only armed correctly when the throttle switch was on R. With normal throttle it Beeped once on full-throttle, and then twice when I released it. Thats not correct. where are those 5 beeps? What's going on, can anyone help me?
On one occasion it went full throttle so I had to disconnect the packs to cut-it.

Has anyone had any problems with the ESC like this? What did you do to fix it?

Any help is greatly appreciated as I'm dead in the water!
