studdering mamba monster?

[hockeyhead019]

hey guys,

ok so i have a mamba monster system in my 1/8 ofna buggy and the problem is that it is studdering like i will have the throttle gunned but then it will pause a couple seconds into the line... here is the link to the video... don't worry about not being about to see the buggy just listen to it when it sounds like it suddenly cuts and then goes again. it's not me :( any advice would be great

(i'm running a 2200kv motor on 4s)

it sounds like a really high rev and then it cuts

any help would be great thanks guys
