Naff all in it.
The SkyRC ESC's are brilliant because they're affordable. I wouldn't ever buying a LRP/Nosram/Orion, they're SO expensive and after trying them there's no performance in it what so ever.
I've even ran REALLY budget ESC's like the Bullistorm 120's that were around a few years ago, I think they were £16 a go and even accepted the Hobbywing software!
I run an aluminium cased SkyRC now. It's affordable but has the lovely aluminium casing which is robust and keeps my electrics cool
