Engine Problem Diagnosis UMX Carbon Cub


Junior Member
Hey all. I have a used carbon cub SS that I bought online for cheap. I replaced an elevator micro servo and found out the original motor wasnt working. I replaced the original motor with a newer 2500 kv motor that is now on the MK2's. I noticed that sometimes in flight the motor will cut out for a few seconds even while the throttle is engaged. Any idea what is up with it?
