Mosfet Mod jittery and jerky, help?

Hey all. I've had my zip zap se mosfet mod by micro amps. It worked great for a while. Now all of a sudden it is jittery. I mean that when it accelerates it goes then stops for a split second and goes again and cuts out for a split second and goes again. It is much faster but it just seems that it is jerky. I am also having trouble steering this thing. I haven't found the right adjustment for it yet. I charged it many times before each use. Do I have a bad connection somewhere? Is my battery crap already? Anyone have any suggestions?

Thanks

umm...are the batteries in your controller fresh or freshly charged?

Talk to MicroAmps..he did the mosfet mod...and i'm sure he has an idea about what's going on. I would say more, but the last mosfet i did was on a regular zz, and i don't know exactly how MicroAmps played w/ or replaced that 3v reg to get those insane results he has.....

im guessing its your antenna. sounds like your range crapped out. check the antenna wire to make sure its still attached to the board.
