I have the new airgoil stab on my KR2S and also incorporated 4" wide
aerodynamic balances that go up to the front spar of the Horizontal. The main
reason I believe they are called aerodynamic balances is because the
couterweight
for the balancing of the control surface is in the airstream not in the
fuselage. I seriously doubt there is much aerodynamic help as far as the
"feel"
of the control. I cannot prove this of course but I can attest to the fact
the the KR2S is much more stable than the KR2. As Mark Landford and a couple
of the others who flew mine. The pitch is sensitive at high speeds but it
requires a considerable amout of force to displace the stick from it natural
center. What I mean by this is that the stick will stay put , you can let go
and the plane stays rock solid, moving to stick takes some pressure but very
little movement is required for a large pitch change. Then plane flies best
when you let go of the stick sometimes. Maybe the aerodynamic balances help
in this centering affect - im not sure. The main reason I installed my
elevatore this way was just for the easy of installing weight to balance and
it
looks cool! I didnt wan a bunch of weight inside the fuse on an arm I could
not
have access to. The weight is now permanent and I dont worry about it.
Just make a descision that works... build it once and move on... Flying time
is
here!
