I have posted my POH and W & B spreadsheet at

http://www3.telus.net/elfrench/RV-10_main.htm



Take a look and tell what you think



Thanks

Ted,  

   

I hope I have transposed your numbers correctly to an excel spreadsheet.  

   

If I have, I comment as follows:-  

   

<![if !supportLists]>1.    <![endif]>Your numbers suggest that you can’t carry 4 adults and full baggage because you will be overloaded and outside aft C of G  

<![if !supportLists]>2.    <![endif]>Your numbers indicate a potential problem with aft C of G at gross take off if you have two adults in the rear seats. This problem gets worse as you burn fuel.  

<![if !supportLists]>3.    <![endif]>There seems to be an opportunity to move some weight forward and get a better weight and balance spread. With pilot only, you are still well aft of the forward C of G, and at gross you are aft of the aft C of G  

   

Regards,  

John Cleary

I like your POH.  It seems to be very comprehensive.  I might steal  

it to use as a guide to develop mine (that is the idea? right?).

 Correct on all counts.

  

 I doubt that any of the 10's out there are much different. If you want  four adults in the plane, then you need to be careful what you load in the bagg  compartment.

  

 There is an opportunity to shift weight forward during construction. I  have the 3 blade MT prop which I understand is a bit lighter than the Hartzell.  Also, my panel is a bit lighter than some I guess. Its GRT displays.  Other  than that, I'm not too sure what one could do to shift the CG  forward.

  

 Still a very useable aircraft for a family with 2 kids, or one big  kid.

Just curious, what is your battery configuration?

I would like to take the opportunity while we're discussing this

to ask for something.  If everyone who has a POH that they're

willing to share would send it to me, just email it to me

directly.  I'd like to compile a list in my TIPS area where

people can gather a dozen or more POH versions for them to use

to make their own.  I heard from another builder today that

they got one that didn't have "Lean aggressively" after engine

start on it, so they added it, but then they saw that it was

on mine when I sent it...so obviously things change along the way

since mine was used as a foundation for many offshoots.

Having a variety of them available would give builders some good

food for thought as they put their own together...especially in

situations like Dan Lloyd...his would be the first Subie one

available.  I won't have time this a.m. to put them out on the

website, but if you email them to me within the next day or so,

I can have a page ready tonight/tomorrow.  If you send me

your W&B, I can put that in the same area.  There are a lot

of creative people out there, so it's bound to generate some

good information for others.  Also, if you update it, just

send me the latest and it's easy to swap in your new version.

We just flew a 4-hour flight with 4 big guys and baggage with no problem.  It gets close to the aft CG, especially when you burn the tanks down, but doesn’t really go aft of it unless you start putting extra weight in the tail to offset the “nose-heavy-ness” of the plane.  That’s why I won’t be putting any extra batteries back there.  This plane can carry 4 adults with bags and full fuel with no problem if you build it right.  How may others can claim that?  Cirrus have 650 lbs full-fuel useful load if you are lucky.  A new Saratoga next door to us has 450 lbs full-fuel useful load.  They sure are lucky to have those extra 4 seats in the back, because it looks a lot like a 6-place on the ground.

Yeah, a person at my airfield just bought an older Bonanza  35 (not sure the year or model) and found that no matter how he tries, he cannot  get both kids and his wife, full fuel and baggage for a long cross  country.  He'd be okay on take off, but be seriously out of CG to the rear  by the time he was wanting to land.  Van's did a nice job getting this to  be a real four person plane.
