I purchased 4 racerstar 2205 2300kv motors as spare for my wizard x220 but I hadn't used them (everything exept the motors fail on that thing).
I wanted to build a cheap, more reliable, lighter and faster quad so this is what happened.
I unknowingly ordered a clone of the GepRC leopard. It's cheap, sturdy, has chamfered edges but the battery strap is too short.
As far as I know, nothing can beat the price/quality of the Mamba stack so the choice was easy.
