I could have timed it that way, but weather and personal scheduling conflicts have pushed my plans out slightly. I'm a [long time] student who has transitioned from an LSA to an Archer. I've flown it a number of times with my CFI in anticipation of this but now just need my solo endorsement signed again.
Sport Pilots, and those many, many who hold other certificates but are flying with SP privileges, can now legally fly a lot more/bigger/heavier/faster airplanes than they could yesterday.
