Peter,
Sorry if this is a repeat message. My email keeps changing itself from text to
HTML, so my previous post on this subject would have come through blank for
some.

You are correct about the pitot system and stall speed.? However, flutter is
all about velocity of the air rather than pre
They used to also have camping at the YMCA.

Correct. I stayed there the entire week in 2010, great place, YES ice in the
hocky ring. You can camp on the indoor grass football field, NO TENT PEGS so
you need a free standing tent.

Hi Neville,?
There is no so called ?kit. You buy the plan's. ?Which comes with the manual
and all the drawings. With that there's enough to scratch build you're plane.
Then there are many parts that you can buy that are pre made from NV Aero.?

My KR-2 has a single 2.6 pound counter weight on a remote 18-inch arm mounted
in the fuselage for 100 percent balancing of the elevator.

I should add the caveat that I have no cables in my elevator controls.
Strictly a push rod configuration.

I would echo exactly what Rob said. I have flown my KR with the original plans

newer tail with the 0009 airfoil and have flight tested it to 215 mph IAS.
Neither tail had counterweights and neither tail showed any pr
Jeff; I've read the article and am very concerned. I'm a CFI so what I teach
determines pilot's behavior in practice. I want to read more before answering,
but I have four observations: 1. The Mooney turbocharged models do not vary Vne
(IAS) with altitude. 2. sailplane manufacturers lower Vne wi
Jeff; small correction- 190 IAS is aerodynamically equal to 190 TAS @ standard
conditions. Your pitot reacts to the dynamic pressure of impacting air
molecules, independent of density altitude, just like your flight surfaces
will, so flight testing to 215 IAS has been demonstrated without flut
We're back from Osh, and I would like to take this opportunity to thank all

Come to think of it aerodynamically. Doesn't elevator horns themself act as
counterbalances,

as long as my elevator cables are tensioned properly,I should not worry about

?I'll let someone else tred on that. Maybe some weight in the counter balance
is better than no weight at all?

The design does not require any balance weights on the elevator, just the
ailerons.

?My counter balanced eleavtor horn?has limited area for adding enough weigt to
static balance the elevator.I need approx 2.2 pounds on each side. Should I add
as much lead weight as possible and forget about it. or should I?not install
any?weights?in the elevator??
