to your plane?


100LL will kill the spark plugs in a 13B. The lead contaminates the
ceramic, limiting plug life to around 25hrs.

You're initial install for the 13B will be MUCH less expensive than a
XP-360.

You're initial learning curve and work load will be MUCH greater for a
13B than a XP-360. (Just about any plans you can buy will show a motor
mount and plumbing for the 360. You're on your own with the 13B, unless
you're building an RV.)

Read the 'fly rotary' mailing list archives to learn more than you'd
ever like about installing the 13B.
