Oh my god..... I had no idea there was such a single point of failure in our new 30% Extra with a DLE55. Seeing how it spends 75% of it's time in some type of gravity defying manuever 20 feet or less off the ground... that is a disaster in waiting.

I am about to start the 5th gallon of gas flying it so I guess by the established timetable described it is about due to fail. I have been flying stuff since I was 10 in the sixties - but I am new to large gas models. I am not flying again until I get a replacement NGK - it is a chance I am not willing to take over a mere $6 for an $1,800 worth of plane! Heck... I will even replace the plug in my 12 year old Cub with a G23! I am so bad - I have never even cleaned or gaped it!

Thanks for the good advice!
