O.S.
Engines .46 AX
What
can I say about O.S. I started my hobby with an O.S. .46SF in
1989 and I still have that same engine (still runs too!).
Follow
the instructions on break-in and you will have a reliable engine no
problem. You can use an OS #8 plug and get VERY good
reliability
out of it. I have sometimes taken a Heli Enya #3 plug and
after 2
gallons of Heli use, put it into an OS .46 and let it be.
Don't
run the OS too lean and it will last a long time. Don't forget to oil
it for storage. Many people don't do this and the bearings
rust
over time. Close that throttle opening when not flying too.
For
my 40-50 sized ARF, I'll use one of two OS .46AX engines I have in it.
