Nothing in this post is to be negative towards Castle, as their products are fantastic quality, and you can't go past their A/M service.

But you said Leopard Copied/Cloned your motors?

How is this so? I have a Leopard 5692 1340kv sitting here. ( The visual build quality is excellent - I'm yet to run it though. )

Castle doesn't produce a motor of this size (This motor has been around for awhile) and nothing close to it. So there is some obvious R&D being done with these Leopard motors and not blatant copying, as you guys have suggested.

I'd lean more towards them being Castle influenced

Just my 0.2c.
