While I highly doubt that a proper calibration would ever cause these problems, the factory calibration is stored on the victor permently. You can revert to it fairly easily.

To reset the Victor to it's factory calibration, and start from scratch, you need to power it with the cal button down. In detail:

1. Power down the bot
2. Press and hold the cal button down.
3. Power up the bot
4. When the indicator light on the Vic flashes green, release the cal button.

You now have the factory calibration, which depending on the sticks you use can give you close to full range. I am not sure about this years sticks, ours were way off and peaked early. Use an older model if you have it, I trust them much more.

I'll just note here that the 883 and 884 are very much the same speed controller. The diffrences are in the deadband around 127 (4% on the '4 and 10% on the '3, IIRC), and a 40 amp rating on the 884 vs the 883's 30 amp. Otherwise, they are pretty much the same. I don't really understand why they would give you such funky results. The only thing I can think of is that your calibrations are off. When you return the stick to center and release the cal button, you have to be extreamly careful the stick comes directly to center and stays there. This years sticks are realy bad about this.

This one has me pretty stumped. I would be amazed if you got several bad victors all at once. Heck, I would be surprised if you got one- Innovation First makes some high quality stuff.

Perhaps all the victors were victum of some freak electrical storm?
