# Test 2020-3 # 4 grain 54mm Purple Pig motor with Aerotech igniter in 3-inch test mule flown on 11 October 2020 at October Fun Fly in Argonia, KS. Used 4-grain 54mm Kosdon case, Loki-style nozzle with about an 0.390" throat, forward closure had pressure sensor and EasyMotor protototype mounted. Four grains with 0.625" cores. Burnsim called this a 72% J-493, with about 2.23 sec burn time, and max pressure on a relatively flat burn of 752.8 psi. ## Results ## Perfect flight, no damage. However, due to firmware issues, the EasyMotor captured acceleration data but no pressure data.
