I have heard nothing but good things about the Hobbywing ESCs. After trying this one as my first, I doubt I will ever pay full price for another "branded" one again--maybe for a Castle or something on a really expensive build, but certainly not for an e-flite or great planes ESC which are probably just rebranded ones anyway and cost 2-3 times as much.
I'm using this in an e-flite Cub 450, and it has performed flawlessly.
