If (when) I build another cowling, I'm very tempted to make the spinner a 12". The inner part of the prop doesn't do anything but stir up the air, and the bigger spinner helps streamline the front of the plane.

Before I started the project, I had the same questions as you. Nothing that I saw for sale in any of the catalogs looked very good to me. Then I was given a broken spinner off a Cessna 177. (Production spinners have a tendency to crack in the area where the props comes through.) Since it was free, I figured I could play around with it a little and see if I could get it to work. I ended up cutting about 10" off the tip and then building my own backing plate. It turned out very nice...and the price was right. You can find broken spinners at most aircraft repair shops. Take a look at a manufactured spinner on a flyable production airplane, and then use that design to adapt the shortened spinner to your airplane...and build your backing plate to fit.

And, guessing from the background in the photo of the KR-2, it sure looks like Arizona desert. Or Nevada. One of the ads on the site is for a black BD-5. Has the same marble back-ground, but also has an e-mail address. Bet if it's not the same guy, he knows the guy with the KR. The e-mail address is: wtb3@sedona.net And Ron is right. If that KR is not carbon-fiber, you better hope it hasn't been left out in the Arizona sun too long. Well, here comes the nurse with my medications and straight jacket again.

Ok for all of us old people, back in the earley 60's, i think 60 -62, mother Mopar (Chrysler to the underprivliged) came out whit what they called long ram engines.How this translates to airplanes is this, they wanted to be able to get ther land yats up to speed as quick as possable,which means low end torque.Now we are running at realtive low rpm's, so we need low end tq. If anyboby remember's these cars, the intake runners went from one head all the way over past the other head and set above the ext. manafolds. These engines had thier max tq. before they got to 3000 rpm. So i was thinking, how do we do this for ower engines? I called Mopar Performance, the performance divison of Chrysler and asked about this. The feller told me the formula for this is 8400x rpm = intake runner length. So 8400 x 3000 ( what most kr's run at) and you get 25.20 " of intake length. I realize the cam ect., playes in to this, but this is how they did it. It's got a lot to do with sonic pulses and a bunch of other juink most of us wouldn't understand.I 'm not saying the intakes that are pre made are not the right length or any of that sort of stuff, i've just never heard any thing on the subject.There are some other stuff i had in mind, like a foolproff fuel injection for the KorvaiR motor, and a way to have your cake and eat it to for the ignition, but i'll wate till tomorow.

This pic show the two eyes removed from the wing side and the center one removed from, in this case the flap or a KR the aileron side of the hinge. http://rvflying.tripod.com/p1070003.jpg This pic shows the two halves mated together leaving a 1.5" slot. http://rvflying.tripod.com/p1070004.jpg This pic shows the pin position center of the hinge for the cut mark and .75 marks for the 90 degree bends. http://rvflying.tripod.com/p1070005.jpg This shows what the final arrangement looks like. Looking back, I believe you can do this before you mount the hinge as the flat stock is never cut and you will insert the pins anyway before you attach the hinge to a spar. http://rvflying.tripod.com/p1070006.jpg For my final assembly, the elbows will be positioned inside the joint with small holes drilled so that safety wire can be inserted. Yes, the bends do come out of that 1.5" slot.

Dr Dean reported the upper bracket angle of about 60 degrees and built his as such which resulted in a healthy amount of camber at the axle, and other guys have built their gear with no camber at all.
