With my speed i turn the sensi on with no paint in and pull once, the speed will fire full auto for ages and in bursts! It is brand new and the trigger is as it was when bought so slack. I have heard some one say "a well set up speed......" but how do you set it up? what should id o to it? I dont have a clue why but is it extreme bouncing or something?I dont think the rate at which it fires any hopper will keep up with it, it also does this but less violent when the sensi is off (sensi is as was when bought) , do you know why exactly? It is brand new so nothing should be wrong with it? I just dont think i will be able to play with it as it is. let me know as im a little worried, cheers
