Hi Lynn=2C
This all started with your very limted knowledge of Rotax engines and some
derogatory remarks. I do not know what you are trying to prove. I have f
lown Kitffox and Avid aircraft with Jabiru engines and they do not perform
very well in slower aircraft with high drag. Not that the engine is bad
=2C they probably work very well in airplanes like the Sonex or the KR2 whi
ch are much faster. I did some checking=2C and the torque at the prop flan
ge of a 912ULS is higher then that of the Jabiru 3300. Also at the rpms th
at the engine is turning in a Rotax 912ULS is in a perfect range. This make
s the engine/aircraft combination very efficient.. Rotax did a good job o
n that of that engine.
As a Tech Counselor and president of EAA Chapter=2C I give facts to people
about the 912 engines=2C give them a ride and encourage them to to ride in
a Jabiru powered aircraft. That is all it takes.
This is fact. P51 Mustangs used liquid cooling along with the same type ge
ar reduction as the Rotax. What I don't like about the 912 is the price.
They have no competition=2C and there is no other engine out there in that
hp range with their record or performance
I know some Kitfox'ers with 2000 hours on there engines. No problems=2C no
top end overhaul or anything. Liquid cooled engines are here to stay. Ju
st look out your car window.
I still don't know what the countdown to 1000 means.
Just being honest=2C and I have flown Jabiru powered aircraft and just wan
t people to make good choices. Thre is a lot of money and time involved=2C
almost impossible to change later=2C unless you have very deep pockets. T
he bottom line is. Do your homework.
Also RV4 builder=2C 80% complete. Yes=2C an aircooled O360.
With a closing remark=2C I would rather be an intelligent donkey then a sma
rt ass.
