Truth be known, that's probably how the RAF48 should be set up, which is what Dana did. Really, the tail needs to be angled down 1 degree for perfection with a 1 degree root incidence, but I'd rather have the tail off by 1 degree than the whole wing off by 2.5! Besides, the tail's probably off by 1.5 on the stocker anyway. These tail numbers are not exact, just what I remember from setting mine up a few years ago. But you're right that the shape of the airfoil is sufficiently different that the aft spar needs to be raised or, you'd end up with even more incidence than a stocker. The numbers for the incidence and washout of the AS series was determined by Mark Lougheed through some pretty amazing CFD analysis (electronic wind tunnel) work. He's one of those guys we drove away from KRNet with all of our superfluous email about 2 years ago...

According to the current issue of Experimenter magazine, the gross weight and stall speed limits for the Sport Pilot License are 1200 lbs. and 39 kts. It looks like Mark Langford is going to have the first KR-2S that is Sport Pilot License legal. THere is only one knot difference between the SPL regs. and Troy's plane. Marks flaps should give him more than the one knot needed to be Sport Pilot License legal. Assuming that the FAA approves the SPL, we may be looking at a resurgence in interrest in the KR by all of those pilots that have lost their medical. The Experimenter article mentions that the FAA is having a hard time with the no medical part of the new regs. What else is new? What we are going to be looking at for the next iteration of the airfoils is a wing that can meet the requirements without flaps. We only need a slight increase in lift without increasing drag at cruise. I don't think that reducing weight is going to get us there as Troy's KR-2 is one of the lightest ones around.

Sometime in the next few weeks, I'm going to need to make the decision on what kind of flaps to build. I need to freeze the design before I start cutting wood. I would like to know the relative merits of the various flap arrangements in the context of the KR2 airframe. Like, split flaps vs. hinged flaps vs. fowler flaps. My first inclination is to go with the fowler flaps, but the split flaps with piano hinges, swinging from the bottom of the rear spar would be the simplest to build. Any ideas would be greatly appreciated.

I know for a fact that the heated air from the oil cooler has been used in quite a few Dragonflies that are stationed up north. The reports are that they work very nicely and the air is clean (no funny smells). If the air from the oil cooler on a VW can heat the cabin I am sure it would work as a carb heat source but why not use the exhaust? The oil cooler may not warm up fast enough to provide carb heat during the early phases of flight and the exhaust pipes are hot almost instantaneously. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ http://www.evansville.net/~boeing/project_viking/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: How to Make Mim's PIG GO From: Mike Mims Date: Mon, 11 Oct 1999 17:25:40 -0700 X-Message-Number: 20 "Ronald R.

Red fuming nitric has a extra oxygen atom in molecule when compared to NOS. Yes, the dentist use it in small amounts to relax you. I had it floating in my test cells all the time, its heavier than air and stays near the floor ( both nitric acid and NOS [ nitrogen tetraoxide]). When our socks were sweaty the socks decayed when they were washed. Both liquids boil at less than atmospheric pressure, the material in the tanks are liquid and fume when release at atmospheric pressure. Rocket engines burn the substance as a liquid.

My VariEze traveling toolkit included a piece of sandpaper and a filler called Marinetex. Anytime I found any nicks in my Aymar Demuth wood prop, I repaired them on the spot. Marinetex should be easy to find at boating/marine shops. It has fiber reinforcement built in and drys fast.

Well, I've looked at them all, and I almost did the hinged at the bottom of the aft spar thing. In fact, I posted a drawing of it a couple of years ago at http://home.hiwaay.net/~langford/flap.gif . I think it would work fine. Using my X-ray 20-20 hindsight, I'd say that might be the ticket! Fowlers require a complex mechanism and don't provide the drag that I really felt was necessary. Of course you could use a belly board, but now you've got something else to screw around with while landing, as if you didn't have enough already. Simple flaps could be built like the flap in the drawing above, but wouldn't give you the drag either...

The jury is still out on th new airfoil. That's all I will say but please make sure that you have the piloting skills required.
