One of the guys that owns competition ele. races at my track every week. He lets guys use the charger and all of its features. I have played with it and it is great so far and yes it is the same size as a regular 35. You can adjust chargeing amps while in the middle of a charge and it does a real time graph of the charge taken. It looks very cool every pit should have one. And better yet if the sales are good on the new charger he said they would stick money into building a new improved motor dyno.
