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.
