John Edwards wrote: > Has anyone flown a KR-1/Corvair combo? I don't know of one, but Richard Shirley has a 3300 Jabiru on his KR-1, which is essentially the same power, but lighter. Some weight in the tail would be required, and the wing loading would be high, and landing speed correspondingly higher than with a lighter engine. But that's essentially what I plan on doing, with more wing area and a longer tail to tame pitch sensitivity. Loads of fun would be assured, as well as 200 mph plus, straight and level. Steve Trentmans's turbine KR-2T has flown plenty, but it's a gas-guzzler, at something like 12 gph. There are details from Steve at http://www.n56ml.com/strent.html, and also in one of the Pine Bluff gathering sites on www.KRnet.org. Mark Langford ML at N56ML.com http://www.n56ml.com

I agree these are learning platforms. As to the effect, I think of how minimal stall strips are and yet they have a major effect. BTW, the F4U Corsair, arguably the best piston fighter ever made, had a dangerous tendency to snap-stall the right wing under a couple different conditions during landing on a carrier and during a abort when power is suddenly added. A 6" stall strip added to the left wing changed the whole situation for the better. Someone mentioned affecting the structure of the wing, and I would also be concerned about creating a stress point at the corners of the openings for these things, from which a crack could extend.

KR> Weight And ballance
Kr friends, I have maybey a stupid question. We are almost at the point that we will start with the engine mount. So I have heard that there is a possability to calculate the distance. So this I will all understand. I want to do 1 weight And ballance sesion (2 pax, 1 pax, full fuel, low fuel). I want to do an exstra weight sesion without Wings. This all outside. Is there a possiblity to calculate all the data so I can do a w without wings so we can do this inside, to check that the engine mount is oke. Or do you all say, this is not possible And you need for a good check in all times the wings.

"Has anyone got any tips on how best to attach it to the ply bulkhead." Hello Peter, I used stainless steel truss head sheet metal screws around the perimeter. Both sides have the traditional piano hinge and the top has the full width (radius) angle for the forward cowling so the only place I had to add screws was across the bottom. Don't forget the Fiberfrax between them and good luck with drilling that titanium. I used cobalt drills and a lot of oil on the stainless and it wasn't what I would call easy. I would assume the titanium is going to be tougher but also lighter. Stephen Teate Paradise, Texas The information in this email is confidential and may be legally privileged.

The obvious first choice is to go with conventional sailplane-style spoilers that are essentially hinged flaps that deploy upwards off the upper surface of the wing, but the ones used by Mooney are interesting in their own way. They are the Precise Flight "SpeedBrakes" and they operate scissor-style as they emerge from the wing. Picture here: https://preciseflight.com/general-aviation/shop/speedbrakes/ and they do have a system available for experimental aircraft but they want $4595 for it ;o) They are electric, the set weighs 9 lbs. but that includes electric actuators. A clever builder could come up with a mechanical scissors motion and dispense with the electrics to save the weight of actuators. It obviously took a great deal of engineering and testing to determine the best place to put them on the airfoil. Anybody got a wind tunnel? ;o) Just more food for thought.

KR> KR-1 Corvair...
Does anyone know of a KR-1/Corvair that has flown? I have a KR-1/VW1835cc that I fly as my daily flyer. I am considering upgrading to a Corvair 3000cc since this is the lightest version in the Corvair line. Has anyone flown a KR-1/Corvair combo? John E
KR> Weight And ballance
Weight and balance CG,center of gravity, is a sum of the moments[arm x weight]of each piece divided by the sum of the weight of each piece measured from a common datum point.The arm being measured from a common datum point.This is how I computed radio changes in aircraft.Measure the component distance from the datum,multiply that with the weight of the component.This becomes the moment for the component.Add the moments to all components and divide the sum of the weights of all components=CG.Aft of the datum is positive and forward of the datum is negative.The datum point can be any point the designer wants.I believe Ken used the aft face of the main spar.Any thing I say may be wrong.Works for me.Tommy W.

KR> Weight And ballance
Weight and balance is simply a summation of weights and moments. If you know the weight and centroid of the wings then you can certainly do a good calculation without them. On the e-3 they often do the final weighing without seats, paint, and other things. Those are added back later. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site/mykr2stretch/parts-for-sale On Jan 20, 2015 9:24 AM, "stefkr2--- via KRnet" wrote: > Kr friends, > I have maybey a stupid question. > We are almost at the point that we will start with the engine mount.

KR> This morning's flight
Had a nice flight this morning to breakfast in Pagosa Springs, CO roughly 100 nm north from Los Alamos. Flew there along with a 200 hp RV-8, a 180 hp RV-7, a 160 HP RV-6, a Cirrus SR-20 and a Tri-Pacer. By comparison, my O-200 powered KR is a couple of knots faster than the Cirrus SR-20, seems to fly dead even with the 160 HP RV-6, is just a few knots (7 - 10) slower than the 180 HP RV-7, and gets badly smoked by the 200 hp RV-8. The Tri-Pacer got a 10 - 15 minute head start for a 100 mile trip and arrived in the pattern at the same time as the KR both ways. This was cruising there at 10,500' and home at 11,500'. Beautiful flight in the snowy mountains today. This weekend I swapped out the standard 100W aircraft landing lights for a pair of 11W LED landing lights from SuperBright LEDs.com. These LED lights were made specifically as drop in replacements for the 100W Aircraft Landing lights, so no modifications were needed. Cost was $20 per light with $10 shipping. -Jeff Scott Los Alamos, NM
