KR> AS504x wing skins
And I should mention that Steve Glover at nvAero has spent a lot of time and money making a set of molds to build wingskins for the new airfoil, so thanks to him, you can now buy a set of skins if you don't want to build them. They are primarily for the 2S, I think, another reason to start with a 2S and skinny it down to KR1 width (or wider). I said earlier it would need more rudder than the KR1 plans, but meant to say "vertical stab and rudder", not just rudder. Mark Langford ML at N56ML.com http://www.n56ml.com

KR> NVAero KR1 fuselage kit?
I looked over the very nice nvaero site. It appears that there is not a fuselage wood or fiberglass kit for the KR1. (not popular?) so I guess that means plans build. It is great that the wing skins, landing gear/wheels/brakes, canopy, wing attach fittings, control stick, are avail. What about the control surface hardware and rigging? I'm guessing whats not compatible (if anything) from the KR2 would be off the shelf at aircraft spruce. In fact, if we didnt have nvaero, I wonder if the entire plane could be plans built? (would have to solve the canopy problem, and fabricate landing gear). Also, one wonders WHY do the plans "may have extended lead times" nvaero is GREAT to have though :)
KR> Flaps versus belly board versus spoilers
HI Larry, Not sure what you mean by "the KR is not a design that call for spoilers"? They definitely kill LIFT which takes care of the "floating problem" of the KR.. They would work on any airplane when placed in the proper location. I've got several Moni motorgliders which utilize them and they will float like a KR if you don't use them. Originally a set of doors were installed on both sides of the main wheel pant, but the most it did was cause a nose down pitch attitude. Spoilers were the solution. If you're using spoilers, you don't have to "point the nose down to dirty up the air flow".. They will stop the wing from "flying" very effectively. In a lot of cases you actually have to keep power in to cut down on the descent rate to keep the plane flying. I know there are other homebuilt designs using spoilers. One type raises up out of the wing like a pair of scissors. The ones on my airplanes deploy like a belly board except they are on top of the wing. You don't need very big ones to kill the lift. Normally installed outside the prop diameter in the root portion of the wing for best lift killing.. All these designs work well. You just need to figure out which one you want to use, how easy they are to build/install and enjoy! Just my .02.

The KR is not a design that call for spoilers.? The only shortfall, if you can consider it a shortfall, is the need for deployable drag in the landing approach.? It is a very slick design that makes speed control in landing? a bit tricky.? It will also float after the flare if too much speed is carried on the approach. Effective flaps or a speed brake are both proven solutions to speed control on landings.? The speed brake is probably the simplest to build but effective flaps may offer other benefits beyond simply adding drag.? If you're building to fly, go with what's proven.?

KR> First flight of the year
My first flight of the year, 1/11/2015 with my oldest 12 year old son, Juan Eduardo, we flew to San Nicolas, Buenos Aires landing and come back to San Pedro, the flight was 50 minutes on very hot day, 95? f out and 101? f into the cockpit San Pedro landing was at 1470 feet over the soft runway (grass), in San Nicolas was at 990 feet with a density altitude of 2170 feet. the climb was very soft to keep oil temperature below 248? f, the cruiser to 1500 feet was comfortable if we forget the heat. you can see a video of flight here: https://www.youtube.com/watch?v=bv8x8p5JXg0 Saludos Eduardo Barros San Pedro, Bs.

KR> Jabiru 2200 - KR1

One more bay would help, but I'd go for two, along with more rudder and horizontal stab. A larger rudder will improve spin recovery also. Might as well start with KR2S plans and narrow it down. We had that conversation last week, so check the archive. A typical VW is closer to 160 pounds. I plan to build something similar, but with Corvair power...

KR> Jabiru 2200 - KR1
Couple things, I have a Jab 2200 on my current plane (Avid Mk4). I was thinking of selling the avid and purchasing everything needed to build a KR1 with the proceeds. One of my EAA buddies remarked "no one builds those anymore". To me, that means nothing. The KR has great looks, performance, and ease-of-build. I found a page somewhere that had numerous single seat planes that were supposedly "better", but none looked as good, or had the features. I believe that a KR1 with the 85HP Jab and the Diehl wing skins at full length, would cruise far and climb fast, and stall slow enough to be LSA. The Jab weighs 140LBS, which I believe is less than a Revmaster type VW and prob about the same as a minimal VW engine. I wonder what engines have been used on the KR1 though. It seems there are so many more KR2's, for example youtube has almost no KR1 vids, which is too bad... It also would be great to know if any KR1's are flying with the Diehl wing skins not cut down, and what the climb and stall speeds are. One other thing I wonder about is how well they recover from a spin. (If thats an issue I'd just put a BRS on it, or wear my emerg chute)
