I've put my P-47 loss behind me and I am finishing my next project. Question, how will I know if I've done any damage to my engine. A guy at the club said Zenoahs are known for soft cranks. It wasn't a lawn dart, but was a high speed inverted non-landing. Should I just put it in a stand and run it...? I noticed a "slight" deviation on the hub with the magnet where it comes past the sensor. Is my cranck bent...? What to do....?
