Hi Dean,
I used the stick on weights just inside the nose and held with a couple spots of epoxy so that I can easily remove or adjust it. She's ready to fly with an all up weight of just under 10 lbs...not the lightest, but I think it will serve me well at this point. Bob's CG is slightly forward of the published one which is a surprise. Thanks for your help.
Steve

Hi Steve,
You have to keep a sense of humor.
When Bob measures his old ship, you'll have a pretty good idea: I remember it as flying rather well.
Do use the ugly stick-ons until you really know where the CG belongs. Then you can cut into the works, if necessary.
Your DB soft mount: is it the one with the aluminum "T"s, or on wooden rails.
You can bolt lead or brass to the front or outside of the "T"s, fairly easily.
While I realize that this is blasphemy, as long as you're not staring at the wong side of the 5 Kg limit, a couple of ounces won't kill you.
The remarkable thing is how sensitive CG adjustment tends to be with today's pattern planes:
move the battery 3 inches, and you get maybe 2 mm CG shift. Sometimes, that change makes all the difference in the world.
later,

Dean,
You are a funny guy! Thanks for your advice. I
realize that the spinner
weight is just not a viable option. My fuel tank is
forward of the CG and I
have placed my battery in front of the tank at the
bulkhead. I am using the
DB soft mount on a TT 120 2 stroke and am not using
a nose ring. there is a
ply former that is just behind the nose of the fuse
and I found that I can
just fit a bar of the stick on weight in there. I
hate to add weight to any
plane, but it needs to be done. I have about 38" of
DB fiberglass rod from
servo to elevators. This is for static balance. I
have always had to move CG
aft after flight testing and I wonder how accurate
the published Finesse CG
is. It's my hope that after flight testing, much of
this weight (about 3 oz)
could be removed. Thanks again.
BTW, when responding to a post with Outlook Express,
do you cut and paste
the original post? If I use the reply Icon, my
message is only sent to the
