There are now 5 of the TGY 52's running at our field. They all run great. Pretty scary for such a cheap motor. Scary for the LHS and the other engine importers that is. One of the motors did have aluminum machine shavings caught in a red grease that packed the rear bearing. It was pretty obvious when turning the motor over by hand. It ran fine after getting sprayed out. Just a FYI. Lots of motor for the money.
