Recently it ran very rough and changing the plugs fixed the problem. The plugs that produced the rough running engine are the RE7A L and RE9BT iridium plugs that are standard with the Renessis car. These plugs have a thin layer of slightly moist carbon on the porcelain. Any suggestions for cleaning? Can I use a standard air operated blaster like is used on A/C plugs? I believe these plugs cost around $35! Should I be using the different plugs for the Renessis in the A/C? Ed - Thanks for the engine data from your last flight - I plan on running some full power static tests on my A/C later this week. Dennis H.
