 ground.=0A=0A=EF=BB  =0APlease don't overanalyze the Jab vs Rotax decis
ion.=0AKevin is right, it is apples and oranges.=0A =0AThose of us near sea
 level, you are fine with a normally aspirated  engine.=0AFor those flying 
out of 5000 foot MSL airstrips and climbing in and  out of =0Amountains, yo
u can't beat a turbo.=0AIf you want super long range (ouch my bladder hurts
) you need to look at  =0Aspecific fuel consumption or cruise fuel flows.  
=0A=0AMy Europa trigear holds 20 US gallons useable (yea the new tank holds
 a bit  =0Amore) and at 4.5 gallons an hour, it exceeds my bladder capacity
.=0AGeared vs direct drive is a mute point.  They both work.  Geared  turns
 the prop =0Aa bit slower, direct is a shorter prop.  This is not a  factor
 for the Europa's =0Aprop limit of 64 inches.  The Jab runs on AV gas,  and
 Aviation consumables and =0Ahas a higher specific fuel consumption.  The  
Rotax can run on car gas without =0Aproblems and is very economical at crui
se, and  performs well at higher =0Aaltitude...  (It also gives neat airsho
w  departures.)  Cooling is not an issue =0Ain my bird at all during climb 
or  takeoff.  But there are those pesky hoses and =0Athe coolant radiator t
o fool  with in 5 years when I better change them.=0A =0AI have found my ea
rly early 914 is not the engine of the new 914s.   The new =0AJabiru 3300 i
s not the same engine as the original solid lifter  engines.  Kit =0Amanufa
cturers who saddled themselves with only one engine  choice have come up 
=0Awith carburetor, cowl and cooling changes which have  made their engines
 more =0Auser friendly for their aircraft.  There are  some idiots flying w
ith Celsius =0Ainfo in the EFIS and telling the  prospective buyer the engi
ne is running super =0Acool.  Thankfully, no one I  know is doing that on p
urpose.  Rest assured, any =0Achanges from the primary  engine recommended 
by the aircraft manufacturer will =0Aneed some tinkering.=0A =0ATruth be kn
own, I don't have time to tinker on my own plane anymore, so I  need =0Aa l
azy mans fire wall forward for the trigear.=0AThat is why I have a Rotax an
d an Airmaster Prop.  To me it is  just easier to =0Amaintain and work on t
his combination.  It is as close to  FADEC as I can get =0Awith my wallet. 
 Climb and dive, winter or summer, just  smack the throttle =0Aaround and i
t takes it.  No oil leaks, shock cooling,  taxi cooling, or noisy =0Aprop n
oise requiring ANR headsets to limit my  flying.  Although those pesky =0Al
eaky tires required me to make new wheel  pants for easy filling since it s
its =0Aa lot...=0A =0AWe are tinkering with the setup right now of the olde
r model Jab and  Rotax in =0Athe shop.  Tuning is an issue.  When the storm
 damage is  fixed, we'll fly more =0Aand report back.  Same with the Airmas
ter two blade  vs three.  The setbacks =0Awe've had have slowed us down and
 removed labor and  financial assets, but we =0Awill press on.=0A =0ANote: 
 Keep your ear to the ground as the recent storm damage across  the US has 
=0Aleft many aircraft owners with totaled aircraft, but they still have  en
gines, =0Aand sales may be on the horizon.=0A =0AWe have a new US owner.  T
hey are Mike and Erin DePeugh of Pekin Il.  Ken =0AGresham flew him in his 
Europa and he was hooked.  I'll send some  pictures as =0Asoon as his plane
 and he arrives at the shop in May.=0A =0AHave a great week.  I am off to m
y son's graduation and will have my  first 4 =0Aday in a row break since 20
06.  Ed and Chris will run the shop as I  may not =0Awant to come back to w
