The launch on April 26th & 27th will have lots of special things going on, but one that folks have been asking for a lot is a night launch.
We have secured a special waiver from the FAA and CLT allowing us to have night operations from 8 untill 9:30 PM on the 26th.
We've posted the rules over in the "Contest Info" section (in the right column) so you can get all the info there. We decided to go a bit larger with engine size due to the number of requests, but keep in mind that our hard ceiling is 1,500' AGL. We're capping motors to I-impulse, and you can do up to a 3-motor cluster as long as your total impulse doesn't exceed the I impulse class. No multi-staging or air starts and you need to make sure that the rocket is illuminated through the entire flight.
So go read the regs and get to building!
