was fiddling bout with the receiver, plugging connectors in and didn’t turn power off. Something appears to have blown as there is zero power now. Fuse is good so thinking I may have blown the speed controllers or the RX.

I know it sounds daft but are the connectors that you’ve fiddled with the right way round? I’ve done this in the past and discovered that when reconnecting the cables in the rx I put them in 180 degrees out to the normal +- and signal markings.

I'm assuming you normally power the receiver from the ESC. If you have a separate battery for the receiver, try that, with only a servo plugged into the receiver with it. If it works, then look at the ESC again.

Thanks guys. Will try that.

A meter* to check voltages is generally a good thing. Just randomly swapping things about without knowing what is, or is not, working is a short cut to some kind of disaster.
If a 3 pin connector is plugged in the wrong way round, in all present day radios that I know of, nothing happens**. A 2 pin, on the other hand, has the potential to do damage by putting reversed voltage into a circuit that was not designed to cope with that kind of mis-handling.
On a lot of modern radios, it is easily possible to insert a plug between the rows of pins. Got that T-shirt.
* Digital multimeters. They start surprisingly cheap, worth every penny.
**Maybe an outside chance that the bind pin might have been given a chance to do something strange.

Raflaunches was right, I had a connector in the wrong way.
