Emphasis mine, I disagree with you here. 1.25oz is nearly .08 pounds. Get four fans off the 'bot and your looking at over a quarter of a pound! If I can loose weight by removing a fan or by drilling 22 holes, I'm chucking the fan first. Being able to instantly loose a quarter of a pound would have gotten more then a few 'bots under in the past. Heck, I've had robots on the scale over by a tenth. Thats one fan and some change.
If the fan isn't doing anything, and on low current motors it isn't, why keep it if you have the option? It may not be a good idea on a CIM or FP motor, but a globe? I wouldn't hesitate to remove the fan, even if I wasn't in dire straights to make the weight budget. It's just more weight that can be used for something useful, like larger wire.
As always, your mileage will vary. It's obviously outside of IFI's and FIRSTs recommendations, and teams that choose to do it should know the risks. But it's legal and does save weight. Doing it for fitments issues makes less sense to me, but hey, I've done it before for the same reason on non FIRST related stuff. Haven't killed a Victor yet.
