Shimming in 428 is perfectly acceptable. As to 424, it kinda depends on the local flavor of rules. Some areas it is fine, others it is not.

Status: offline 		The supplied rear bearing looked pristine and felt buttery smooth - no pieces missing. I replaced it with another rear bearing from a TT Pro 40 which ran an entire season with the same plug. Raced it this weekend in 5 heats and 2 practice flights @ 16,500 RPMs...NO PLUG FAILURES!

Hard to believe, but it looks like the culprit was the REAR BEARING!

I'd check the bearings. If one of the balls is starting to spall, the nearly microscopic bits of metal will take out plugs about as fast as you put them in.


Thanks for the report.

Perhaps something is rubbing - foreign matter might be distorting a plug, too,

Do you know the difference between Tiger Woods and the average golfer?

Status: offline 		Way to go Jim. You are the man! Now that we have that prob. solved I want to know if anyone has taken out the TT 40 pro muffler apart and taken out the center piece that looks like a baffle? I want to take it out to see if i get any more power out of the engine.

Status: offline 		The TT40 muffler is usually self disasembling... We had a guy take his baffle out... won the race... the CD ran a piece of nyrod up the outlet after the race and disqualified the contestant. In fairness... he thought it was legal and everyone was doing it. I take mine apart, clean it good and put it backtogether with JBWeld to make sure it stays together even if the bolt fails.
