19:39:02=0ASubject: Re: Europa-List: Re: JABIRU etc. Keep your ear to the
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
