Ed,
Congratulations on the successful rebuild and safe
flight back to home base.

I've been off email for the last couple of days, so
I'm trying to catch up. 

I made a trip to SC, first in about a month and a
half.  Had a good day yesterday with three flights,
but only 1 1/2 hours total.  It was pretty bumpy. 
Engine is running very good, and no problems.

Hoping to get in at least 3 hours today.

Steve Brooks (fuel it and fly it)
