Well.. I have a mikrokopter hexa xl, was flying great but had a full loss of power at about 50 feet and crashed. I replaced a boom and motor. Then I thought I had a bad bl but it was the power distribution board. Had new one installed with all new bls. Recalabrated everything and now when I take off I get an immediate yaw. Checked radio. Everything in center. So I hooked up mktools and went to motor test and scoped each motor. When I was on 50 the scope showed 50 for all motors. Then I tried the same by starting the copter and increased power. What I noticed is that the motors on the scope are all over the place. Also, motor 1 decreases in power until it is about 8. Attached is a pdf showing what is happening. Is it a bad fc?. Anything would be appreciated.
