I seem to be hearing a lot about bearing problems with Magnum Fuel.  It is
not very prevalent here in the Southeast, but I would sure like to hear from
you guys that use it.  I can't believe that it would be that hard on
bearings...

There is a lot of Magnum fuel used on the West Coast with no noticeable 
difference in bearing life.  Most of the people using the OS140 engines have 
switched to stainless bearings and don't worry about bearing failure after 30-60 
flights anymore.  The stock bearing failures were occurring regardless of fuel 
type.  The stock bearing appears to be very susceptible to corrosion even if you 
run the engine dry after flying or not, whether you use after run or not.  
Stainless bearings made that problem go away and the life of the bearings is 
typically in excess of 100 flights with most going over 200. I get my stainless 
bearings for the OS from Jerry Budd at Budd Engineering (aka Rusty Freid  ;-).

YS 4C don't seem to wear out the rear bearings as quickly and we have people 
out here with over 500 flights on YS engines/bearings with no noticeable wear 
problems using Magnum.  Having said all that, doesn't seem to be a problem out 
here.  Lot of Magnum shipped to the Chicago area, and the Northeast (can't 
remember exactly where).

Guys, hope this doesn't launch a tirade of 'this fuel is better, that fuel is 
better'.  Fuel usage is like discussing politics.  I run Magnum because I 
have had very good luck with it, have run it since it was introduced in Denver 
when I lived there.  There are several good fuels out there, I selected Magnum.
