Nose Weight

[Steve Wiggin]

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

Hi Steve,
Keeping in tune with your hazing: it's good to see that you have admitted 
your problem, now you can get help.

Seriously, It's good thinking to keep the noseweight as far forward as 
practical. In the spinner is not practical, and up to maybe an ounce or so 
is practical, right on the crankshaft with one of the Higley heavy prop 
washers.
In the spinner is a bad idea: heavier cast aluminum spinners have been known 
to throw themselves off the plane, and that can really ruin your day. The 
heavy nose ring isn't all that bad an idea, maybe from 1/4" brass sheet. 
Hey, It hacksaws and files nicely. Of course, Nat would make his from gold, 
but he's got money to burn. Replacing the fiberglass rod with cables will 
only get you about halfway there, based on a 1 ounce pushrod.

What kind of engine mount do you have? This may have an effect on where you 
can bolt or glue the weight in.
later,

    OK guys,  judging from all the snide remarks, I must have asked your
collective Holinesses a stupid question. Since I have no components to
easily move, and I'm not going to move the wing tube forward, I guess the
only other thing to do is think about lightening the tail. I am using a DB
fiberglass rod for elevator as called for in the plan and it seems a little
heavy. Perhaps I should think about using pull-pull for elevator to lighten
the tail and avoid the "crime" of adding nose weight. BTW, I don't have
super light weight components elsewhere on the plane. This is to be an entry
level airplane. I wonder what I should do about the "crime" of being new to
pattern?
