Tim,
I know asking someone's weight is a sensitive subject  But would you mind sharing your weight and balance data with the group.

I forgot to mention this....
After flying my RV-10, with the large aux battery array under the rear
passenger knees, and the larger PC925 battery in the rear, I no longer
consider my RV-10 nose-heavy. My W&B's came out in such a way that
I really can't get it out of forward CG. I can get it out of aft
CG though, so the standard planning is needed for loading it up.
I was worried about the nose-heaviness in the past. It's just nice
to see it's a non-issue as my plane came out. Of course, mine
is no skinny minnie.

Weight is 1685. Arm is 108.67 with the range being
107.84 - 116.24. The moment is 183104.25.
The weight should be pretty good. I loaded it up
with everything that was going to be with the plane...
carpets, seats, fire extinguisher, the works. The
confusing thing to me is that one main was about 15lbs
heavier than the other, so I question how closely it was
leveled side to side. Throughout the build, I did not
put any priority to weight at all, but all into
functionality, comfort, soundproofing, electrical backup,
and reliability. So none of the components were chosen
for low weight. I knew the plane had lots of power, and
2100-2200 fpm alone show me that it does just fine.
I have set the gross wt. at 2800 after doing stall
and climb testing at gross, so that makes up for the loss
in useful load. Seldom will I be near that weight anyway,
but at least the ramp checks will always go smoothly.

6.4807 pounds per horsepower. Now if we could get six RV-10s all flying
to Sun N' Fun '06 to cruise at the exact altitude, in the same
direction, at the same time with identical MP/RPM we could get a
shootout on similarities. If I am not mistaken, Aerosport gives
customers a printout of the actual HP provided by the dyno "On reman".
Wouldn't it be great of the other 26 flying RV-10s would please step
forward with weight and hp or the final number for a "Fair and Balanced"
evaluation on this forum?
In that same regard if we increased N104CD's weight by another 45
pounds, hence 1730+ pounds forward = balanced by that depleted uranium
tie down aft. We could do a similar comparison and then duke it out with
the AeroComp/MT/Hartzell crowd for RV-10 supremacy.
Add a turbo-normalized engine for High Altitude Idaho strips with.....
Oh that's right... that is Hot Rodding.

Tim,
Thanks for this information. It will be helpful in planning locations for aux battery location, etc.

It would be very nice for the flying RV-10s to add their info here...

Dan has created this wonderful tool for the better good of all. It
even has the ability to do sample loads by clicking on the N-Numbers
of the listed planes.
