does a 3.8 perfection work?
 

does a 3.8 motor of perfection work in a ZZ SE (10A03)
i think it's a old pcb and does this motor goes fast ?

because i can't choose between this one and a tomy 3.0 motor.

I would reccomend you go to the local radio shack and pick up one of the kits that come with the orange and purple motors. That would be best.

He's right. The purple rs motor is the best. I have all of the perfection and super perfection motors and none of them come even close to the Nitrous Express motor from Radio Shack.
