  • Condensation in engineering compartment

    So there I was last week. Started out as a good patrol, then submerged boat. Water in battery compartment and engineering compartments. Drained water and allowed each section to dry.

    Powered on boat. Dive planes, level-controller, rudder are responsive. Brushless motors are inoperative. Receiver on boat displays ONLY red LED.

    What's wrong?

    Thanks!

    Did you take the receiver out of its case/shrink-wrap, blow it down then bake it at low heat overnight? Could be mineral deposits are shorting across a chips contact points on the PCB. Do the before mentioned steps then scrub the chip contact points with a fiberglass brush till they shine. Test. Sing my praises.

        Thanks for the phone conversation Dave!

        I'm experiencing two issues yet:

        No response from motors for propulsion, and no response from ballast system.

          To be sure it's the receiver that is bad put a servo-setter to the ESC and ballast servo. If they work that way it's a sure thing the receiver is broke. Do those checks and get back to me.

            Possible that if the ESC wires or ballast wires are soldered and you used heat shrink tubing that the water got inside them. I found that as David said blow the electronics with air. Be patient and wait a day or so for all to dry. Also, may need to re program. Also blow out all RX wires and connectors. It is possible that the RX shorted when you powered up before all was 100% dry.
