Also consider this...are there any kr2s's flying with winglets? Winglets
have the same structural loading changes as extending the wings.

Strength is not my limiting factor...the @as5048 has about a 25% increase
in strength alone due to the taller spar sections...add on top of that my
spar caps are 10% thicker.

Hello All,
I'm going to use the 5048-45 airfoil and want to confirm whether the
following would be the right approach if I wanted to lengthen the wings
one foot on each side...
1) Lengthen the forward outboard spars one foot, but still taper them to
the dimensions given for the rib at the end
Larry, I still think you have too much prop on your plane. When I had my
Sterba on the O-200 cut down and pitched a little less on the M-1 my climb rate
went from about 900 FPM to about 1,300 and cruies speed increased about 8 MPH.
I would expect you to get very similar results on the KR. You
Actually, I was talking about true airspeed. It does go up with altitude until
somewhere around 8500 feet (on my plane), where it levels off, then starts
dropping off again as you go higher. The altitude that happens at is dependent
on your combination of wing, drag (including weight) and HP.

Jeff,
Are you speaking of indicated airspeed here? I would think that

I haven't normalized it for temperature, but rate of climb drops off to 200
ft/min at roughly 14,000' at 1200# gross, or 15,500' with a lighter load. In
either case, it's higher than I am going to fly without O2, although better
performance up to those altitudes would be nice. That's with the

For sure the shorter wings are a winner down low, but if you ever want to fly
out west where altitude is critical, longer wings are a hands down winner.
That's not to say one can't fly at higher altitudes with the shorter wings, but
it's sure easier with a higher aspect ratio wing and more wing

I will eventually make my wings longer. Right now mine are only about 4"
longer than th
12 matches
