David    The short answer is when fitted with an Electronic Speed Control  with Battery Eliminator Circuit.    You should not need a receiver battery.

However if your MAIN battery is less than 5v  most BEC can not work properly

Try looking at this link

it gives a simplified diagram of how things should be

cheers Tom

I know this is stating the obvious - but is the switch on the ESC in the ON position ! - easy to overlook.  Small switch, 3 connections, 2 wires - switch position should be over the 2 wires

Hi Dave     Again the short answer is yes, BUT .  For someone like myself a retired Electrical Engineer its no problem, I still have some electrical test equipment.   For others perhaps not so easy.

In your case, I am concerned that there is no switch on the ESC (you don't say what make it is) I wonder if the ESC has a BEC fitted. Try your radio system with a Rx battery and servo only (no ESC) if that works connect the ESC, motor etc. and the Rx battery, see if that works. If it doesn't work then I think you could have a duff ESC.  

Cheers Tom

Hi Dave,

Something does not seem right here - Lets do the obvious No.2 ...

You are not plugging the ESC into the battery connection of the receiver by mistake are you ?

Hi Dave

If you try all the above excellent advice with no luck then it does sound like a duff controller,

Was it new when you bought it? (I bought a "new" one off ebay but it was blown when I tried it out)

Is there any chance that you connected the battery wires the wrong way around?

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.
