    I had a problem with my Neptune. The prop I had (custom, non-stock prop) was causing the fuse to blow after a short while in the water. That would not be your problem because once the fuse blew the sub would not start up until a new fuse was put in there. Does your sub have anything custom done to it or is it all stock?
    Another thought, does your lead acid battery in the sub carry and maintain a full charge? You may want to check it out.

    I had another thought, there are LEDs on the power board, it will give you an indication of errors. I will see if I can pull up the description of LED. I recall that the red LED flashing means a problem and solid all is O.K. While on the bench and exterior off, can you recreate the error and see the lights?

    Good the battery is o.k.
    So, running it out of the water produces no problem?
    Yes, it could be overheating. Again, on mine it would blow the fuse. Turning off the transmitter wouldn't cool it down.
    Are you running the sub in a chlorinated pool? Does while diving does the sub come to the surface and then does not respond? I am wondering if you are losing signal. I was at a pool in Southern California and I could not go deeper than a meter or so before it would surface on its own.
    Have you taken the rear apart to see if there is any binding or debris on the shaft?

    Hi Martin.

    A loss of ALL controls makes me think of either a loss of signal or an intermittent on-board power loss.

    As you say control returns after 5 minutes with TX off, I would suggest that you try an alternative transmitter to eliminate this possibility. The 5mins off may give your Tx battery time to recover??

    Power-wise, do you run a receiver battery or a BEC? If the latter and if its overheating then a thermal cut-out in the esc may cut off the power hence it may be worth trying a battery as a temporary fix. (I have an ESC which suffered a total BEC failure in mid pond)

    Finally, Have you invested in a new box of swear-words.....

    Best of luck

    John

    running the sub in a lake can normal get 2/3 meter no problem
    while diving does the sub come to the surface,, no
    no , loss of signal
    rudder will move very slowly, no other controls
    transmitter is ok, i use it with other 2 subs ,all ok

    Hi Martin.

    If the rudder servo is moving very slowly it suggests the servo is only getting a very low voltage.

    Suggest checking for nipped cables and trying a replacement receiver battery

    Puzzling one this.

    It does suggest either something overheating and then cooling down (BECs on ESCs can behave a little like this.) or battery problems.

    The only way to go is start swapping items one by one(I don't know about the Thundertiger electronics. They may be all integrated - which makes swapping discrete items difficult.)

    Does it give the same problems when swimming in the "home test tank"?

    Any luck on finding a solution?
    I contacted Jon who is the new distributor for the Neptune/SeaWolf. He also thought the ESC could be overheating. With that thought, you might want to take the rear apart and check for any binding on the prop/shaft/bushing if it seems to be O.K. then open the cylinder and see how the motor turns. I have not oiled my motor, but it might be needed, but I am not sure.
    I really want to get you back in the water.
    Also, can you run your sub in the tub and get it to stop? If so, what are the LEDs looking like?
    Do you have the manual on the sub? In that manual it has what the LED pattern indicates. If it indicates it is o.k. it eliminates a portion of the diagnosing.
    Peace,
    Tom
