To all,
I got the scales from my local EAA and did my W & B today. Empty weight
seems to high at 820 lbs this is with a Corvair full oil, interior installed,
drained all the fuel that the drains would drain but didn't run the engine
until dry, it has wing lockers, landing nav and strobe lights, aileron trim,
full panel of steam gauges plus GPS.
The CG computes out OK but still seems heavy on empty weight. What ya think?

Hi Dave,
First weighing on my XL with full panel, essentially no interior, no
fuel, no oil, and Jabiru 3300 was around 715. I think the
Continental or Lycoming adds around 100 pounds, and I guess the
Corvair would be similar.

Don't complain. Mine is 850 pounds empty.
That's supposed to be done with unusable fuel still in the tanks, so you're
probably pretty close (if not a touch low; I'd expect to be able to drain
fuel from the tanks that the engine can't use to run reliably).

David,
My 601XL with a Corvair engine weighed in at 841 lbs. The weight was roughly equal
on all three wheels. I didn't think I had added that much weight either, but
I guess the scales don't lie. I honestly don't know where all the extra weight
comes from. Beyond "norms", I have a single-axis autopilot, insulated firewall,
upholstered side panels and seats, parking brake valves, dual sticks, long
range fuel tanks and an instrument access panel,? I don't have wing lockers,
aileron trm, wheel fairings, right side brakes and only have a little paint.?
I didn't do any "beefing up" of the airframe as I built.? So I guess it is what
it is, and I wouldn't know where to reduce weight by any significant amount.

My understanding is that the Continental is heavier than either the Rotax or
the Jabiru. The Lycoming is heavier than the Continental, and the Corvair is
heavier than that.
You pays your money, you makes your choice, I believe the phrase is.

Jim,
Your understanding of the weight of a Corvair engine is not accurate. The Corvair
weighs slightly less than a Continental O-200.
As I understand it, the popular engines used in 601 by order of weight from lightest
to heaviest is: Rotax, Jabiru 3300, Corvair, Continental O-200, and Lycoming
O-235.
I don't know where the Subaru engines fall in the weight order.

Interesting. Thanks for the update.
The data I've seen on Corvairs has shown them to be heavier than the
Continental. I do have the data sheets on on O200, and an O200 laying here,
awaiting rebuild. But, as I don't have a Corvair, I'll bow to your knowledge
in this area.

Jay,
Well it's good to know mine is inline with others weight. Mine also has the
dual sticks I forgot about. At least the CG falls within limits from just
pilot and no fuel to two people and all the fuel up to 1320 gross it's just I
will have to watch the fuel weight and baggage with two fair size people
aboard.
Thanks, David Coberly 601XL / Corvair

I am using the Odyssey 680 mounted on the rear carry thru behind the
passenger seat as in WW's 601 manual. I'm really not sure on the max cht and oil

Mine is 815. The description of your airplane pretty well fits mine
except for the engine. Mine has no paint on the exterior, just
polished aluminum. I also have a cabin heater installed that weighs
about seven pounds and cabin and firewall insulation.

Earlier XL's have a lot more 016 in them.
Newer ones have a lot more 025. Mine is mostly 025, except for some 016 in the
tail.
Don't know if that would make much difference or not. I'm guestimating that mine
is going to come in around 775 with Corvair & BRS and minimal everything else.

Same here polished except fiberglass parts painted I also have cabin heat
valve and ducting so it sounds like I'm right in the ballpark with my weight.

After a two weekends of disassembling, deburring, priming and cleaning (damn...I
hated the plane last Sunday) i started the assembly and riveting of front fuselage,
getting ready for top skin and canopy.
And with these lucky charm brake pedals, there is no way I can get into any trouble
in the air. :D
