Priority number one is getting the lowest trust line. Engine height for
cooling is a consideration with a air cooled engine but most cooling
problems are with ground operations and that goes away when airborne.

Sounds great. Keep the reports coming.
Rick Lewis has been quiet for a long time is he still building?
Haven't heard from Bob Green in a while.
Any one else out there building VW powered Kolbs? I know there is at least
one on the fence.

Nick C/Gang:
I find the lower the engine and prop the better the performance. I have
my 912ULS as low as it will go with about 1/4" clearance between the
lowest point of the crankcase, the banjo fitting for the oil return
line, can run a 72" prop and still have 3/4" clearance between prop tip
and tail boom.

Rick,
My Xtra is heavy. 691 lbs empty. All the extra "doo dads" and creature comforts
really add up.

You need to put that bird on a diet. My plane is 598 lbs empty but wet (oil
and unusable fuel). That is with a full enclosure with storage pockets and
coat of silver UV paint. I was real careful with weight. No more than three
threads showing anywhere. That big 1-1.25 redrive bolt had 20 extra
threads showing, not any more. If any part looked heaver than necessary it
got lighting holes drilled in it. For example the diehel(sp) accessory case
was designed as part of the difocal mount. That meant it is heaver than it
needed to be the way we use it. It has maybe 30 half inch holes drilled in
it in addition to the two mounting ears cut off. One of those holes is real
handy to stick a screw driver into as a fly wheel lock. I also don't have a
heavy magneto. My battery is a fairly light lawn mower 12 AH battery from
Walmart.
Not my idea, but a fraction of an ounce multiplied a thousand times in the
build process adds up to be real weight. If it doesn't serve a purpose leave
it off or cut it off. I wasn't even close on things because I didn't want to
make anything weak. I'm sure I could get another 30-50 lbs off and not
effect strength.
Enjoy it the way it is but when you start putting a passenger in it, it will
be over gross limit real quick.

My VW with all accessories (oil cooler, redrive, etc.) weighs 181 lbs dry. Rich
N has done an amazing job keeping the weight down on his plane. This winter I
will see what I can do to reduce my planes "pork". I was suprised when I weighed
mine. The pounds can add up fast.
