 Hi, Rich...
 
 RM>  I had the Goldberg Extra some time ago - best flying bird I have ever
 RM>  had -
 RL> Ya... the biggest problem that I had was that it loved to float when
 RL> it hit ground effect, even deadstick.  Our approach was over a pistol
 
 I LOVED that long gliding approach - made my landings look good !
 RL> range with a 10 foot wall, maybe 30 yards ahead of the runway.  The
 RL> official approach pattern was to come in BEHIND the range and make a
 RL> turn to final just past the wall.  I could never get the hang of that,
 RL> so I'd just approach over the range.  Problem was, if I didn't clear
 RL> the wall by less than 10 feet, I wouldn't be able to hit the runway
 RL> within the first 20 feet, and if I touched down any farther down than
 RL> that, it would run off the end into the grass.  I never did master
 
 Sounds like you had a real tough flying field - we are into our second
 year with our new field - grass is finally beginning to take hold - our
 strip is 800' grass with a 300'x25' paved section - no nearby obstacles
 so we get into a habit of long, slow approaches - that keeps most of us
 from flying at neighboring strips where the approach/takeoff lanes are
 crowded.
 RM>  then (but a little larger) and have been giving some thought to the

 RL> I've not heard good things about ST3000 reliability... of course, your

 I haven't used the ST 3000 (1.8 cu.in.) yet since I obtained it last
 year from a "closing-out" modeler in Florida - he was using it in a
 US1000 with an 18x6 prop - don't know about RPM but it should be around
 8000-9000.
 RL> aerobatic bird like the Extra, I'd definitely prefer to overpower
 RL> within reason.  The Goldberg is a .60-.90 2cy or 1.20 4cy kit.  I've

 I had the ST 90 2-cycle on mine and it pulled it real good - man, I hated
 the day it went in - no recovery and complete destruction.
 RL> I don't think I've ever built a Midwest kit.  Mine were Global/Hobby
 
 My last Midwest kit was the Mach One pattern bird - I am still flying it
 and it's about 25 years old - been retired several times (when I wanted
 the radio in another bird) but it still comes back and flys nicely - the
 engine is an OLD Veco 61 so it isn't competitive with the modern engines
 or pattern birds - it just flys along in a most enjoyable fashion.
 I like your tagline - I've had my problems with Win95 also.
