Hello Steve McIntosh, You wrote:
1) =9CThanks so much for your input!=9D
You are welcome.
2) =9CYour thoughts on both of those suggestions??=9D
See the following:
3) =9CI have a prop balancer installed.=9D and =9CI'm
thinking about removing it.=9D
First some clarification about terminology. A dynamic, versus a static,
propeller balancer is a device like this:
http://www.aircraftspruce.com/catalog/appages/dynavibegx.php
What you probably have installed is a 12 pound Mark Landoll propeller
harmonic dampener. See here:
http://www.geocities.ws/redrive_psru/HarmonicBalancer.html
I suggest that you google this item to learn more about it =93
don=99t take the word of one web site as gospel.
Second, I would not remove your harmonic dampener just yet =93
that is sort of throwing darts at a problem that we don=99t really
understand yet.
4) =9CMy battery, (a garden tractor variety) is located right
behind the co pilots seat. I could move it back some and that may help
as well?? =9C
I would buy an Odyssey PC 680 battery and place it in the far back right
corner of the baggage compartment. See here:

Thanks so much for your input! I appreciate it. All good questions. I
have a prop balancer installed. It came on the plane when I purchased
it. I'm thinking about removing it. That should free up some weight over
the nose.
My battery, (a garden tractor variety) is located right behind the co
pilots seat. I could move it back some and that may help as well??
Your thoughts on both of those suggestions??

Hello Graham, You wrote: =9CThats bit over 38% on my Nose Wheel
!!=9D
I believe that a more acceptable criteria to be used for determining the
percentage of airplane weight on the nose gear is to use the total
airplane empty weight in the calculation.
In your case that would be 285 divided by 1026 which would yield a
percentage of 27.8 percent of the total airplane empty weight being
statically supported by the nose gear.
In my case it is 242 divided by 972 which yields a percentage of 24.8.
So both of our numbers are in the same ball park.
Agree?

Howd'y OC ,
Yep, think u are onto something there below ... ,
just throwing in my numbers to maybe add to the confusion . Going from
my Builders W&B Document i have 285lbs on the Nose Wheel ( creak/groan )
and Mains together ( individual mains wheel weight not shown ) i have
741 lbs ... ( Total Empty weight 1026 lbs )
Thats bit over 38% on my Nose Wheel !!
Cheers,

Hello Steve, You wrote: =9CJust trying to figure how to securely
mount it further back??
The Odyssey PC 680 is an AGM (Absorbed Glass Mat) type of VRLA (Valve
Regulated Lead Acid) battery so it does not require a sealed battery box
nor a vent to the outside of the airplane. See here:
https://en.wikipedia.org/wiki/VRLA_battery
But it does require mounting so that it can not come loose and rattle
around the airplane. The terminal connections also should be protected
in the baggage compartment from any metal contact that could short out
the battery.
I epoxied some very sturdy slotted aluminum brackets into my baggage
compartment. Then used a combination of plywood and non adhesive 2 inch
wide Velcro brand hook and loop tape to strap the battery into place.
See here:
http://www.fastenation.com/products/velcro-brand-fasteners/sew-on-fastene
rs/velcror-brand-polyester-hook-loop-sew-on-tape.html
I know that many people have a low opinion of the holding power of hook
and loop tape. I am also aware that the FAA recommended replacing Velcro
style fasteners for ELT=99s. See here:
https://www.aopa.org/news-and-media/all-news/2015/march/11/faa-recommends
-replacing-velcro-style-elt-fasteners
But I would like to emphasize these points:
1) This is not adhesive backed tape and there is no dependency upon tape
adhesive for any holding power in my installation.
2) The tape is looped back upon itself so that there is no dependency
upon the hooks and loops not separating for any holding power in my
installation. The tape itself would have to tear before the battery
could move.
3) There are multiple loops of tape in both directions over the plywood
surrounding the battery so that it would take an extreme amount of force
to tear the multiple loops of tape.
4) The installation is both light in weight and provides ready access to
the battery.
OC
PS: Make sure that you take into consideration your wiring needs (large
enough gauge) when planning any move of the battery.

Hi Owen,
Yes, I have the Landoll harmonic prop balancer. There is wood pieces
glued down behind the co pilots seat that hold the garden battery
secure. I will look at purchasing the other battery. Just trying to
figure how to securely mount it further back?
