Hi all, ive got one of those Super Mono x Speedboats which is a fun little toy, well it was until yesterday. I was down the local pond and after it capsized and it didnt self right this time,the motor was running constantly. I pulled it out with the prop spinning flat out. Now after disconecting the battery and putting a fully charged one in it makes its little tune as usual and the rudder briefly moves but nohing happens when i pull the trigger. Any ideas please ?

Sounds like some moisture has got into the 'works' try taking all the covers off and leaving the model, with internal electronics exposed, out in the sun or on top of a warm (not hot) radiator.

Any trapped moisture will evaporate and this might sort out the problem.

You will be surprised at how much moisture will still be trapped in and around the components. A simple test is to very carefully dab thin strips of tissue paper into the components and see if the tissue shows any signs of damp.

Jon, my wife and I have had that happen more then once. We did like Paul T said about useing the sun for heat if you are going to be at the pond for awhile. If your heading to the shop, we use a hair dryer on low heat or our heat gun (the one used to shrink coverings on planes) again on the low heat setting at 8 to 10 inches from the items and keep it moving back and forth over them.

Hi, well its been in the warm all day and its had a good 3 hours worth of a hair dryer warming/drying it out. Unfortunatley theres still nothing happening apart from the tune it plays when you connect the battery and the reciever red light lighting up…..Anymore thoughts ?

Its always possible that the electronics died when tried with residual damp still lurking in a recess. The damp may have damaged components, especially if power was applied too soon, which means before it dried, and, if any form of heater was used, before it cooled.

Damp allows electrolytic corrosion to happen, the same process that is used to etch metal components. If it happens with a bit of thin wire, there is not much to remove, so it can happen very quickly. Pond water is not very pure, so electrolytic action happens easily. Salt water is rapid doom to anything electrical.

Can you tell if the noise is coming from the receiver or the servos? Did you remove the cases off the receiver and the servos? If you did was there any sign of yuck, looks like corrosion on any of the items in question? If there was use a eraser and go over the solder connections, then clean with denature alcohol (Isopropyl Alcohol) on a small brush and let air dry. If this doesn't work then try another receiver with the same servos or same receiver with different servos. Were you using a electronic speed control or the manual type that is operated by a servo? If it was a electronic then it's probably no good now, I have not been able to repair these myself. Had to buy a new one. Paul
