I am a new Mooney owner M20K model I noticed two times that my electric trim was getting stuck on nose up position after landing , one of the time was during a touch and go, after I realized that I was unable use my electric trim, I had basically to decrease power and deal with the yoke pushing nose down until trim with the wheel trim which was also stuck. It was a bit scare since I have only 10 hours in a Mooney, the CFII that I am training with was asking to keep the power up without knowing what was happening. everything happened too fast, I was trying to tell him and fly the airplane at the same time. This just happened last week
