I have an O-360 Lycoming in my 801 with a metal cruise prop supplied by 

Zenith and the aircraft is certainly NOT nose heavy as apparently some 

801 builders claim.

In fact, if I had to do it over again I would probably put the battery 

on the firewall rather than under the seat to get more weight in the 

front end.

My empty CG is 14.8 in (allowable range is between 12.8 and 22.4 in), 

and I have the shorter horizontal tail. My empty weight is 1310 lbs (I 

have the extended range fuel tanks)

It is not a big deal but with an empty CG closer to the forward limit 

you would have a greater latitude in loading profiles. As it is, when I 

start to load the back seat I sometimes will reach the aft CG limit 

before I reach gross weight.

Hi Larry,



Please forgive me if this is a silly question, but is that 1310 lb. empty weight with full fuel, empty or somewhere in between?  It's a lot higher than the stated 1150 lbs. empty weight on their spec sheet.  It wouldn't surprise me if their specfied empty weights were on the light side for marketing purposes, though.



I remember you said you built yours a little heavy, but I didn't realize it was that much heavier.  It's still plenty for two large people to fly with plenty of cargo, however 



Best regards,

Chris

The empty weight (1310 lb) that I quoted for my 801 is one commonly 

defined as the weight of the aircraft including unusable fuel (about 

4-6 gal), and full oil (12 qts).

The empty weight of the Zenith factory 801 is reasonable considering 

that they have only two fuel tanks, no soundproofing/thermal insulation 

surrounding the entire interior of the cabin as I do, and a lot simpler 

(and lighter) instrument panel.

The one-inch thick closed-cell foam insulation from Wicks or Spruce is 

quite heavy. In fact, in the forward floor I have a two inch layer 

underneath a 1/8 inch masonite sheet and carpet over that. I did that 

because my rubber fuel lines are routed underneath the "false" floor 

through rigid PVC tubing on their way to my Andair fuel selector on a 

center panel (an additional extra weight).

I also installed additional aluminum angles (diagonally) on both the 

top and bottom rear fuselage to minimize "oil canning" during flight 

and glued random scrap pieces of the 1" foam to the sides of the rear 

fuselage as well to accomplish the same thing. I have about 160 hours 

on my 801 and so far have not yet heard any sounds due to flexing of 

the aluminum skins ("oil canning").

So, with all this I think an extra 160 lbs doesn't seem too bad.

Thanks for the details, Larry.  Much appreciated.  You've got a wonderful airplane, to be sure 



Best regards,

Larry,



Is there a reason for the foam other than the oil canning? I suppose it 

helps on sound also. Is there a reason you can't use construction foam 

board. It does seem like a good idea. How about gluing the foam on before 

assembling? Just curious. I'm thinking about using metal fuel lines. Thought 

I would look through the archives for some information. If there are any 

pros or cons I won't find there, I would welcome any input. (as long as I 

agree with it) HA.

Larry,



How do you like the prop you have. What size is it?
