# Test 2020-2 # 4 grain 54mm Everclear motor with pyrodex pellet ignition in 3-inch test mule flown on 10 October 2020 at October Fun Fly in Argonia, KS. Used 4-grain 54mm Brazell case, #32 (0.5" throat) Loki-style nozzle, forward closure had pressure sensor and EasyMotor protototype mounted. Three grains with 0.5" cores (I think!), nozzle end grain bored out to 0.75" core. Burnsim called this a 21% K-788, with about 1.97 sec burn time, and max pressure on a somewhat progressive burn of 923.6 psi. ## Results ## Perfect flight, no damage. However, due to firmware issues, the EasyMotor failed to launch detect and so we got no motor data recorded on this flight.
