[NSRCA-discussion] OS160 Longevity

[Wayne Galligan]

Mike,

Omega fuel has castor in it and that may be the very reason your bearing is holding up.  Seems the castor will coat or impregnate the bearing surface to help prevent oxidation.   I have a ST2300 that is 6yrs old now and has countless number of flights on it with original bearing (knocking on big wood).  The first gallon of fuel through this engine was Omega 10%.  Cant prove that this is the case but it may also not be just coincidence.

  I know this may sound like a smart a-- remark, 'but I'm still waiting for the dreaded OS160 rear bearing failure.  I know it will probably happen when I least want it to, but I've got about a hundred flights on 'mine with the stock bearing and it just keeps on running like new.  I have had a once in a while stutter when it went vertical, but got so much power it just keeps going anyway.  I run OMEGA 15% and OS type F plug, Perry pump.  I flew 6 rounds today, set the ATV to 80%, way too much power on cool days:-) Thanks to Jon and Bob for all their tips, oh and Art too. Noe that I've said this it'll probably croak the next time I fly.
