The last tim I did it, here's what I did. I made 1/32 ply floors for
the servo wells and gave them a thin coat of epoxy so they wouldn't be
porous. Then I got some 2 diameter heat-shrink at the local industrial
electronics store ($5 for a 5-year supply). This is a bit rubbery, not
slick. Cut the

That's backwards. Mass is not the same as damping.
Adding rotational mass (inertia to be more exact)
actually reduces the damping forces relative to the
inertial forces, so it

I just buy it by the tube.One thing else that I forgot to mention was to use
the Marine Goop as it has the U.V.blocker in it.This will prevent it from
yellowing and breaking down.
One tube should be more than enough to do a fuse.

The Gooped fuse has a semi-candy apple finish to it. Plus it is exremely
more resistant to scrapes and scuffing and the fraying of ultracoat that
occur's normally with the typical covered fuselage. I don't recomend doing
wings this was because it dosn't have the torsional rigidity that ultracoat
But in any case, mass balancing seems very impractical in foam-core RC
glider wings.
Not if what you are doing is trying to break the DS speed record as Craig
is. I've seen the wing. You could support the wing tips and stand on the
center section. And it probably wouldn't flex at all. Craig is
I have a very good condition Stratos for sale. $675 without servos and
$875 with 4 Multiplex Digital servos.
I also have a very good condition Organic for $450. The flying surfaces
are brand new/never flown and the fuse is used with the typical landing
scratches. Both are + shipping. gv
I have a chance to get this slope flight completed with the proper
level two witnesses next month. I want to fly a six JR368 digital
servo model for this. (I know, get a paragon.)
Any ideas on battery type to make sure I have the eight hour go?
Sounds like the worst possible plane to use for
On my flaps, at least, I use masking tape. Never had it come loose on me.
If you have a two or three piece wing, and you can get to the servo from
the root, a lot of people say that you can take a long dowel and tap on the
servo from the side, which will pop it free.

Gotta go with Craig here. Everything I've read says that mass balancing a
control surface decreases the chance of flutter

I'm suprised I haven't seen a DS plane with mass balances yet.
