I have a few days off-grid and the internet is billowing with abuse aimed at me.
As it happens, I was looking after Ray's mugs until I can put them in the ultrasonic cleaner that I haven't managed to nick off his bench yet.
Den, for spares I'd suggest you talk to Iain at Draganfly - he's doing impressive things there. Tell him I sent you, but deny all knowledge when he asks about anything a bit dubious that I might be aware of.
They are doing more and more in house fabrication & very good it is, too.
