Hey Tracy;
Lost that email where you told me what radiator you are
using and who makes it. Also, getting ready to make a decision on oil
cooling. Who makes the water/oil cooler system I've heard about, and does
it work???
Thanks again;
Greg

Yeah, kind of disappointing for a bare bones day
VFR airplane. I know where some of the excess weight is:
1) Ran a ground cable to the batteries in the
baggage compartment. Thats 6 - 7 feet of 0 gauge copper. Paranoid about
ground loops/noise in such an electrically dependant airplane. Could use
the airframe as a ground and loose that.
2) Made the exhaust header out of .062" 321
stainless. I'm sure it could have been .030" and would still live for many
years.
3) All the fuel and oil plumbing is Earls
braided stainless. And the oil plumbing is pretty long.
4) Some of the brackets are a little over
built.
5) I have 2 Odyssey PC625 batteries. If I
had Tracy's courage I could loose 1 battery and 13.5 pounds.
I probably should have mentioned that 1027 pounds
includes full oil and coolant. I dont know if you guys are including that in
empty weight. Never understood why the manufacturers dont include oil in empty
weight - not like you can fly very far without it.
Anyway, looks like my gross weight is going to be
around 1650 rather than the 1500 Vans recommends. At least the CG looks good.
All possible combinations are within the limits. This probably due to my
custom cowl which let me move the engine a little forward from
normal.

Mike,
Mine came in at 1090 which is midline for an
RV-6 with a FP-prop. Darn good for a day/night IFR RV-6 with 200h.p.,
though I probably (definitely) gained a few pounds with the latest cowl,
radiator, muffler, foam sound proofing and 3-blade prop. Waiting until
after painting before I re-weight. My CG is slightly aft of
average.
Not sure where you are putting on the pounds, I thought for
sure you would have been under 1000.
No matter, it's going to fly
great!

Weighed the airplane today. Either my wife
and I or the airplane, or both need to go on a diet. 1027 pounds empty.
Was hoping for less than 1000. For the RV guys, how did your empty
weight come out? Incidently, with batteries in the baggage compartment the
CG looks good.

Mike, what airport are you doing your first
flight out of?

Not sure I really wanted to read the bit about
after takeoff engine failure at this point. Too close to first flight to
have that put in my head. I'll probably appreciate this a lot more after
I get some flight hours under my belt.
