Cheers Dan,
Here is the finished unit with the second cover in place it comes in at 28.6 gms.

I left the Rx exposed so you can see the lights for binding and receiver error codes.

It just dawned on me that I could dispense with the flying lead on the battery connector.

I have sat down and had another look at the controller brick idea and decided there were a few improvements needed.
With the connectors coming out on the side the were it put receiver and power switch at the rear where they were vulnerable.
The JST plug was too long and bulky and leaving the whole of the receiver exposed was a further danger.
So I have bought the servo and power connectors out on the other side of the board and replaced the JST connector with two board mounted pins and built the key-way that stops the power being reversed into the case. The receiver is now built in with just a narrow viewing slot for the leds.
Here is the new case lid showing the power and servo plugs.

Here it is with the battery and servo plugged in.

That's looking really neat. How well does it fit inside machines generally?

I haven't got as far as putting it in a robot yet just put some wheels and tyres on.
Here is the original viewed from behind you can see the receiver and switch are rather vunerable.

Here with the connectors coming out on the other side of the board both are moved much further in to the protected area.

I see, that looks like it would fit nicely. Looking forward to seeing it inside a machine.

Just brought the original up to the new standard ready to build a couple of ants for my two granddaughters one of who is mad about purple.

By reversing the wheels you can change the width from 75 mm to 94 mm so would even go in a Flea.

That's really good Peter! All your hard work is paying off. Making my own bespoke controller is on my bucket list, but can't find the time...
If you don't mind me asking, how much does it work out for each one?

The bare boards were around £6.50 each plus about £12 for the components, £5 for the motors and then another £6 for the orange receiver plus the printed case.
So just around £30 for parts so it shows what good a value Rory's controllers are where you get wheels and tyres as well.
Here is the first try at incorporating one in a flipper it came out at 100 gms exactly.
