But lots of luck collecting. The court assesses these penalties, but it's up to the winning party to actually get the money. There's a guy out there who owes me well upwards of $10,000. I expect I'll never see a penny of it.
If you want to conserve battery power, a quadcopter (any type of copter, really) is not the vehicle you should be flying. Get a powered RC sailplane and install an FPV camera. Soar all day.
