Nothing boring about it, because if things stay pointed in the direction 
they are, we soon won't have anything to fly. 

It's brewing over here as well Graham. Some call it the Tea Party while 
others just feel better saying it's conservative thinking but we are all 
self responsibility types.
We are all getting rather tired of the few wanna tax & spend liberal 
hollywood types getting into our pockets and running this country into 
the ground. There is no difference between a dictator and a politician 
if all the politicians come from the same current mold as each other. 
Talk great to get elected that do the same dam thing.
It's time for a business man to run this country not a lawyer or career 
politician. Perhaps it should be the same over there?
Anyone out there that agrees should go to    www.fairtax.org  
Unbelievable fix to a lot of things and they need all our help to get 
thru.

the prop a bit slower, direct is a shorter prop.  This is not a factor 
for the Europa's prop limit of 64 inches.  The Jab runs on AV gas, and 
Aviation consumables and has a higher specific fuel consumption.  The 
Rotax can run on car gas without problems and is very economical at 
cruise, and performs well at higher altitude...  (It also gives neat 
airshow departures.)  Cooling is not an issue in my bird at all during 
climb or takeoff.  But there are those pesky hoses and the coolant 
radiator to fool with in 5 years when I better change them.

The new Jabiru 3300 is not the same engine as the original solid lifter 
engines.  Kit manufacturers who saddled themselves with only one engine 
choice have come up with carburetor, cowl and cooling changes which have 
made their engines more user friendly for their aircraft.  There are 
some idiots flying with Celsius info in the EFIS and telling the 
prospective buyer the engine is running super cool.  Thankfully, no one 
I know is doing that on purpose.  Rest assured, any changes from the 
primary engine recommended by the aircraft manufacturer will need some 
tinkering.

> That is why I have a Rotax and an Airmaster Prop.  To me it is just 
easier to maintain and work on this combination.  It is as close to 
FADEC as I can get with my wallet.  Climb and dive, winter or summer, 
just smack the throttle around and it takes it.  No oil leaks, shock 
cooling, taxi cooling, or noisy prop noise requiring ANR headsets to 
limit my flying.  Although those pesky leaky tires required me to make 
new wheel pants for easy filling since it sits a lot...

> We are tinkering with the setup right now of the older model Jab and 
Rotax in the shop.  Tuning is an issue.  When the storm damage is fixed, 
we'll fly more and report back.  Same with the Airmaster two blade vs 
three.  The setbacks we've had have slowed us down and removed labor and 
financial assets, but we will press on.

Ken Gresham flew him in his Europa and he was hooked.  I'll send some 
pictures as soon as his plane and he arrives at the shop in May.
