My Aerotech Arreaux is ready to fly at the ISOAR launch on July 17. My Arreaux weighs in at 14 ounces without motor. With an AT F20-7 SU, Open Rocket sims altitude at 1,100 feet. Aerotech shows an altitude of !,760 feet on the same motor with rocket weight at 12 ounces. OR sims the 12 ounce Arreaux at !,250 feet. That is a 500 foot difference at the same weight of 12 ounces. What is your experience with OR simulation accuracy?
