Ok great =)
I picked up a couple myself and they should arrive in the next few days. I will compare them to the SK3 5055-280kv motors I already have on my V3.2 board and see how they compare.
I just had another look and it appears the sale is still ongoing and there is still stock available. If people cant see stock make sure to switch to the Australian site using the bar at the top of the HK website to see the availability.
