Thor,

Not very detailed but, see pg 35 of this:

At least it seems to be a very lightly stressed engine.

I question whether you could ever wear out a Micro Max motor.  I know we have run Juniors 60 hours and Mini Max motors could go that long and probably longer.  Considering a Micro Max rarely goes above 10k rpm for a motor that is designed in the hardest use (Senior and Masters classes) that can go 40-50 hours I guess a Micro Max motor could last 80-100 hours.

Thanks for the info and the PDF from Rotax. Amazing that the Rotax motor isn’t more popular in the US, well at least in the west where I live. Hope the SoCal Rotax series takes off for next year.
