    I had a blast, the trip went real good, except for two problems.
  First,  I
had a trailing plug fail , it broke the insulator and would misfire
badly
with full throttle after a few seconds. I think the broken pieces of
insulator would glow and cause preignition. So I just used less than
full power, fortunately don't need full power to take off.

snips....

Great hearing about your successful trip, Chuck.

  I broke the  ceramic
cone (around the center electrode) on two spark plugs when I had the old
engine ignition timing overly advanced.  It just chewed the plugs to
pieces and cause their failure in as little as 10 hours.

Glad your trip was safe and fun - way it should be.
