Darco,

First, the board has a really nice looking layout.  

Three thoughts:

1 - Don't be surprised if the power connector holes are really big compared to the leads going into them.  IT appears that the plug footprint follows the manufacturer's datahsheet specs.  The first time I used a coaxial power plug, I followed the datasheet for the suggested hole size and found them to be way to big.  I have since made them smaller so I don't have to fill the gap with a ton of solder.

2 - You might consider changing the LED silkscreen outline.  I use one that has a flat side near one lead so it's easy to get the orientation right when stuffing the board.

3 - Consider putting some text near the SX and Prop headers that indicate which way to install the SX and Prop keys.  It's easy to put them in backwards and damage the keys.  I always put the text "SX-Key Front" or "Sx-Key Back" on one side of the 4 pin headers so I know how to plug it in weeks, months, or even years from now without looking at the schematic.

Thanks,
PeterM
