Marv,
I forwarded an old post along with my W&B and Vans first Rv10. I have
relocated my batteries back to the stock location and will be removing
the ballast in the tail. I will not weight the plane again until after
paint. One of the problems with moving the engine out is the mount gets
heavier.

Hi guys,
I know some of you are building RV10s, and I have a couple questions for
you...
1) would anyone happen to have the complete weight and balance data for
the RV10. If yes, would you be willing to share it? I'd be happy with
a PDF, Excel file, JPG, whatever.
2) does anyone have an original stock RV10 engine mount available? I
figure most folks will build a custom mount for their rotary so there
ought to be an original mount out there with someone. If you have one
would you allow us to borrow it for a couple weeks, (we'll pay the
freight), or alternatively, if you'd like to sell it, just let me know
how much.
3) Can someone please share the total weight of the complete nose gear
strut, including tire?
Thanks, I look forward to hearing from you.

Phil,
Just as a reference my Renesis RV10 came out with a forward CG. Added 13
lbs of tail ballast until I can relocate one battery after phase 1. With
the ballast N416AS matches Van's factory RV10. Firewall to prop flange
is 47", with a 2.25" cowl spacing. The MT prop is 39lbs. The super
charger is about 25 lbs with mounts. Two radiators, oil/ water exchanger
and two batteries are on the firewall. I also have a full interior and
IFR stack.
If I was mounting a 20B I would stick with 47-48" to prop flange and
move one or both batteries to the standard position. Radiator placement
with coolant and prop weight would need to be considered.
Extreme Composite's
http://www.extremecomposites.com/aircraftparts.htmlhas the molds for my
cowl. The mold was made to accommodate 53.25" to 49.25" from prop to
firewall. Spinner is 15". They also make the cowls and 15" spinners for
the F1 rocket. The upper and lower parts are just shells so inlets can
be added as needed. Talk to Jimmy if your interested. The cowl was a lot
more work then I anticipated.
I have two 400ci radiators with an oil to water exchanger plumbed
between them. No issues with ground cooling during extended runs.
