The SR-1 Project builds on the legacy of legendary record setters in the FAI c-1a/0 class. This is the lightest record class: aircraft must weight less than 661lbs at takeoff, including pilot and fuel. With recent advancements in powerplants and lightweight components, our goal is to push the current record of 223mph to 275+mph. For regular updates, check us out at facebook.com/TheSR1Project.
