I have two of the MVVS 26IFS engines from Pe. The engines run great. I am getting about 8000 rpm on the first tank of gas on an APC 17 x 8 prop. Idles at about 1600 rpm. That's the good news. The bad news is that the test airplane "flew" out of my truck on the way to flying field this morning and damaged the sparkplug wire. It landed on the pavement just right to not damage the engine. The braided cover on the wire and the cap is damaged. How do I get the wire replaced? Can I buy the wire and do the work myself or do I need to send it to the manufacturer?
