What Spark plugs will work in my Zenoah or Chung Yang RC-style engine? What electrode gap is correct?
For the Zenoah RC-style engines and clones, the following plugs work well:
Champion R27C
NGK CR8HVX
NGK CR8HSA
NGK CR7HVX
NGK CR7HSA
NGK CMR8A
NGK CMR7A
This plug works the BEST: NGK CR8HIX Iridium Plug
A gap of .65mm (.029 inches) is recommended.
