Did i burn out my quark

[Puttinstankonia]

I have a quark 125 b and im running 11.1 lipo on a c4 and i wanted to know if i burned out my controller... Yesterday I was running it and I stopped for a second and a puff of steam came out of the controller.. I let it sit for a while and it still works but its not giving me nearly the speed i was getting before.. Did i burn up the controller or the motor... hopefully the motor.... Will the controller still work if its burned out
