Well, when I was installing my zip kit on my piranha evo body, it was chopping like crazy...and I found out, that it was because of bounce.
I put a 5g radioshack trigger in there...yea, its 5g at the tip of the lever. Did you put a new switch in there?
LoL I did the magnent mod, and it was still bouncing fairly bad...Now that I got eyes (TBOARD! WOOHOO!) Its great, but since your T1 has eyes already, it sounds like a different problem...
Firstly are you sure the eyes are still working? Maybe they're off? or maybe they're to dirty and always think theres a ball in the breech? Id suggest giving your eyes a good cleaning...
Also, since your T1 has bouncebeam eyes...perhaps the paint your using isnt good for bouncebeam...and your eyes just go right through them?
Also, are you sure its chopping? Breaking, and chopping are 2 different things. in a nut shell, Chopping is the ball getting caught by the bolt, and breaking is the ball not fitting the barrel correctly, or very cheap paint, and breaks in the barrel. JUST in case u didnt know... but in this case...stop using cheap paint,
aside from that...are you using a stock T1 board? does it have debounce setting? if so, might wanna up that a bit...does it have eye delay? might wanna up that a bit also.
But goodluck...if nothing i said is accurate, or works for you, then igore me, ima moron
