How would you even hook that up while getting enough power to each motor?

I'm assuming he wants to use the third as like a "backup" motor

I think it would be safer rules-wise just to use a weight (besides, you get penny rolls to do that :) )

I would definitely find another solution for balancing weight. Even something like coins might work without getting you into any trouble with rules.

It would be risky, depending on the event supervisor idk if they would allow it.

How close do you guys get to 15 seconds, and how consistently do you get that?

The most common way is to use a potentiometer or rheostat that varies power to the back fan and use that to control your speed. To get to 15 seconds, you need to have perfected your skirt, because if you're moving very slowly, the slightest snag in the track will stop you and end your run.
