BK Controller set up problem

it's the Feiago motor. It was running just fine for the guy I bought it off of. He was running a dsm radio and receiver (I'm not). I've tried 2 different receivers so far but am still having the same problem. It seems to be alright if I ease onto the throttle...but when I hammer the throttle it stutters.

I don't know a whole lot about this stuff...that's why I bought it from someone else and didn't build my own. I was hoping to just be able to put my receiver in it and go...

Like I said, I don't know much about this stuff but I wasn't sure if maybe my receiver was too close to the esc? I've attached a picture of how it is set up.

Somebody mentioned to me that I might need something called a "glitch buster"?

Again, any help would be greatly appreciated
Thanks
