Firstly. hello to all,

I have just started RC model boats, tried the boat out, How ever, when I switch the controller on, there is a sound abit like morse code from the engine. then every so often, when I select the engine thottle on the controller, 'well most of the time' it slowly turns, then goes full thottle, still getting that noise, I still have rudder control.

Any ideas.

Hi Chris,

Check your wiring.

Particularly any sockets/plugs. I had a similar problem whilst testing Pacific Light a couple of weeks ago, were one motor would run intermittently.  Traced the fault down to a Tamiya connector.  My soldering was quite good, but over did the solder !, and got some onto the outside of the pins.  This caused the pins not to sit properly in the connector, when the 2 halves were connected together they only just touched instead of going into each other.

Cheers - Ken

Hi Chris

Are you using an Electronic Speed Controller?

Some ESCs make the motors act with symptoms similar to those that you are describing when they are first switched on. 

If you are using an ESC check its rating against the power draw of your motor.

Hope this is of some help.

Cheers for the info, I checked the wiring looks ok, the some else mentioned the speed controller as well.

I just got to check the transmitter and receiver, done some distence test could be one or both.

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
