What is the total liftoff mass limit preventing a rocket from being classified as a Class 1 Model Rocket under FAR Part 101?
Answer
1,500 grams (53 ounces)
Federal Aviation Regulation (FAR) Part 101 establishes clear parameters for different rocket classifications, and Class 1 Model Rockets are the most basic level, generally requiring no prior FAA approval or Air Traffic Control notification if operated safely. To remain in Class 1, a rocket must adhere to specific limitations regarding propellant and total mass. The text specifies that the total liftoff mass must not exceed 1,500 grams, which is equivalent to 53 ounces. Additionally, the propellant limit for this class is strictly capped at a maximum of 125 grams (4.4 ounces).
