Tackle posted the link to this thread on the Z1 forums. I'm so tempted to order one, I even have it in my TaiwanGun basket ready to pay.
mightyjebus - have you had chance to open up the gearbox? I've seen the pictures, and it looks decent. But the marketing pictures of Specna Orion gearboxes also look decent too, but in reality they are rubbish (at least in the case of my son's Edge).
But £116 shipped. Damn, that's cheap.
