Status: offline 		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....?

When you get it back it will be as good as new and his rates are very reasonable. I have never heard that one about Zen's having soft cranks. Ralph's number is 928-635-2455 or contact by e-mail at rjign@yahoo.com
