I cannot agree however on your statement that it it can be more accurate than a transit. You might approach or even match the accuracy of a transit at times but I don't think you will exceed it. I think a water level is a good idea with only one exception. Water expands and contracts quite a bit with variations in temps. and therefore can give an erroneous readings depending on the temp. at the times different measurements are taken. So long as all measurements are taken during a period of constant temp. then there should be no problem. Also measurements taken in the sun compared to those taken in the shade can vary somewhat. I've spent over 40 years in the construction business and have seen first hand the errors that can creep into a project due to the use of 2 foot levels. (You don't see 2 foot levels to layout foundations for buildings and such, you see transits) I know some levels are better than others and as Mark Lankford put it some are just plane "crappy". It's not always the kind of level being used or how well it's calibrated. It's also human error, no 2 people will read a level the same. What's a centered bubble to one may be slightly off center to another. I don't mean that in a bad way, sometimes you can check something for being level , then check it again and second guess yourself as to whether the bubble is exactly centered. This doesn't even take into account cumulative errors. I will take a good transit over anything I've seen over the years. I can also say with a great deal of certainty that my KR-2s is within plus or minis 1/32" (firewall to tail) in terms of angles of incidence, dihedral, washout-or any other elevation relative to the top logerons at the firewall and tail section. A transit can be set up and left set up if desired and elevations can be taken anytime. The height of the instrument will not change regardless of temp. flucations. Do I need that kind of accuracy----Maybe not!! I did it this way for my self, because I have the ability, the means and the will to get it that way. Builders are free to set their own standards as to what is acceptable to them. >>>>>>THAT' WHY IT's CALLED "EXPERIMENTAL" !!!!!!

The 460F-35 is exactly what I now have (and intend to use for starters), except that mine has twin carbs. The MZ 301 seems like a good choice based on the weight, price and output power. The BMW is too heavy for the power output in my opininion. The 120-130hp Hirth is still my favourite albeit rather expensive in South Africa. They are used in quite a few two seat kit helicopters where reliability is of the utmost importance. Regards, Hennie "Now for the actual reason for my post. I've been looking at a lot of engines lately and have a few I'd like to put out here for comment.

I have a friend close by with a proper KR2 at a slightly more advance building stage than mine, so I am able to compare. Also, we'll be finished at around the same time and he's using the bigger Corvair engine, so I should be able to come up with some interesting comparisons.

The point I'm making, he was the most safe KR builder out there that I knew off, yet a KR still took his life. Being cautious does NOT guarrantee a long life. I've often been told the story of a glider tug pilot from S.A. - Parys (seemingly the most risky thing to do in the eyes of the insurance people). He did this safely for most of his life, but in the end he was killed peddling his bicycle from Parys to the airfield. a Car simply drove over him killing him on the spot. Thus, death (or the lack of it) is not always a matter of keeping to the rules only. That's ALL I'm trying to say.

Are you inferring that people who build to plans die and those that dont survive? You say ,in effect that Sakkie used to pick you out for making changes.-youre alive and he is buried.Please elucidate. ! ! ! Sakkie and the builder were both killed in a KR that many say should never have taken to the sky.Sakkie,at that time CEO of Rand Robinson (SA),really helped to make the KR take S.Africa by storm in the seventies.Untiring,he demonstrated the KR,all over SA.He availed himself to test fly ,and convert the builder to the KR.At that time I was heavily involved in gliding and homebuilt gliders and was devastated when I read even the preliminary accident report.Unknown to Sakkie many changes had been made.It was suggested that the KR took off and could not lower the nose.--both were killed.Investigation showed that the builder had only 5 deg down elevator.The joystick assembly was not bolted to the mainspar--only held on with self tapping screws usually used in metall.It was suggested that in a desperate attempt to get the nose down,the stick and mount were ripped out the spar.Photographs showed quite clearly that the stick had been forced forward.It was suspected (with reason) that the spinner was filled with lead to correct tail heaviness.However the spinner was never found.Also unknown to Sakkie (obviously) most of the bolts holding the wing attach fittings were not in safety.They were not even protruding past the nuts locking fibre.It was a practice to have at least 3 threads past the nut.Many other bolts were not in safety.Aluminuim spacers were required for the undercarriage assembly.The builder (if one could call him a builder) substituted sawn off sections off a broomstick ! ! !. as spacers,also I am sure unknown to Sakkie.The centre secton spars and the outer wing spars were badly crushed at the WAFs owing to over torque of the bolts.The structural integrity was severly compromised.One of the most heartbreaking photos I have ever seen was that of the stick ripped off the spar in an attempt to get the nose down What went through Sakkies mind when he saw the assembly held onto the spar with self tapping screws instead of bolts and just rip off I dont know.This is just the tip of the iceberg I am told.The final inquiry revealed more.This accident reverberated throughout the homebuilding fraternity.and spelled the end of the KR for a considerable time.That was about 30 years ago.Thank goodness the KR still survived eventually.---a remarkable aircraft conceived 50 years ahead of its time.I do hope I am wrong Hennie but your remarks,appeared to exhibit callous indifference.Sakkie may be buried,(no fault of his) and you are alive,but be careful,you may be next.

Problem for me is that all these imported two stroke engines are VERY expensive in South Africa. So, when I have the finances, I'll rather bite the bullet and buy the 130 hp Hirth two stroke engine. This gives slightly more power than the Corvair at roughly a third of the weight which will suite my project like a glove. Even the much smaller Rotax 503's have become very expensive over here. The only other alternative at this stage (if money was no factor) would be the 6 cylinder two stroke 180 hp Arrow engine. But then the Hirth is powering more aircraft (including helicopters) and should be quite reputable by now. Only advice I have is to ALWAYS be aware that your engine can fail and NEVER fly in a situation where you totally have to rely on your engine like flying low over trees, mountains etc. That's a microlighting habbit that will always stay with me. I've seen what happens when you trust your life to your engine and put yourself at un-required risks, I've never been that dumb to this date and it's saved my butt on many an occasion.

Hi Jim, "Hennie, I do not know if you are aware there is a design from Rand -Robinson for a KR-1 with extended wings, a KR-1b motorglider. This sounds like the direction you might be headed" Yes, as far as I can determine (...I've read all I could find on it), no modifications were made to either the spars or WAF's. However, I've allready started to beef up my spars for the AS5048 in & AS4046 out(inner spars already completed), so this is definitely the way I'll go. I'll use Mark's suggested method of using bushings through the spars where the WAF's are bolted through. I'm convinced that this will be perfectly safe for a 20ft wingspan plus the occasional 2 ft each side wing tip extensions. I should have all my spars modified by this Friday, so I am determined to go this way. I'll beef up my WAF sizes and lenghts also although I've been informed that to this date this have NEVER failed on any KR.

I've also allready done too much work to change my spars as promised and will be finished with this change by this Friday, I picked up all the extra wood before gluing and it is not a lot of weight. What is is, is a LOT of piece of mind, so I'm happy with the way I've went. I'll make up a lot of time when foaming and glassing my wings. I've also seen my friend's wings which were built using high density PVS foam and cut with a hot wire - the initial finish must be seen to be believed! It takes less time to do it in this way also. I WILL follow your advice on the bushings for the WAF bolts though - thank you for the idea. Regards, Hennie "I'd bite the bullet and slice the spars apart longways and rebuild them, using the same caps but longer verticals between the caps, leaving you with a light, strong spar, and extra room inside for fuel tank capacity and stuff like bellcranks." ------------------------------ Date: Mon, 12 Aug 2002 01:44:10 -0500 To: "'krnet@mailinglists.org'" From: "van Rooyen, Hennie(SF02)" Subject: FW: spoilerons - Please delete if you are not into modifications Hi Harold, Please promise to keep me posted on the results using this airfoil. I nearly went the same way and no one bothered to answer my question why, of all the new airfoils for the KR, the GAW-1 is the only one which did not gave satifactory results. I've got an old newsletter stating just the oposite. Also, spoilerons have been proven to work effectively, even at low speeds IF they are located in the gap between the extended fowler like flaps and the main wing where they can make use of the high pressure air under the wing for better control response. The Robertson stall conversions on the Bonanzas is an excellent example of this. Regards, Hennie "The wing is a GAW-1 type. It should fly next year." ------------------------------ Date: Mon, 12 Aug 2002 03:20:31 -0500 To: "'krnet@mailinglists.org'" From: "van Rooyen, Hennie(SF02)" Subject: FW: attaching wings at fuselage - Delete if you're not into modif ications Hi Brian, Thank you for the practical info.

I think that spoilerons will safeguard one against this condition as it has the same effect as shortening the wingspan when deployed, so releasing it should give that span back with immediate effect. Also, because it's only applied to the wing that's required to go down, it should not cause any undesired stall behaviour. I can no longer extend my stub wings as my all my spars are built and I DEFINETELY want a single, tapered section of airfoil only on each side - there are numerous benefits to myself in this configuration. A belly brake is fine (I had one on my first KR and from high speed taxi test can verify that they have a pronounced effect at 80 mph.) In my case, however, I require full span fowler flaps as I'm REALLY after a 25 - 30 mph landing speed without slowing the top end down to much. I've searched the net and found the perfect and easy way to build slotted fowler flaps that can also reflex slightly as I require this function to increase my top end speed, compensating for the fixed landing gear and non tapered fuselage. Regards, Hennie South Africa "Way back when I also had the idea of using the existing flaps and making the ailerons flaperons also. My biggest concern is with making the wing tips more suceptible to stalling and therefore spinning the plane when you are low and slow" "I would rather extend the stub wings another 6-10 inches to give me more flap surface." "I would speak to some people that have flown with both belly boards and flaps first." ------------------------------ Date: Mon, 12 Aug 2002 08:56:46 -0500 To: krnet@mailinglists.org From: Kerry Miller Subject: VW 1600 question Message-Id: <3.0.6.32.20020812085646.007af100@pop3.ticnet.com> Does anybody know what the STOCK compression ratio is for a 1600cc VW?

I don't have any info at hand, and am trying to give you a quick answer, but I can tell you that if it's a stock 1974 Type 1 it's 7.3:1, and I believe that is fairly typical. I'm sure somebody can find an exception to that, however...

There is a resistance to flow that water has that is sufficient to introduce error. It was very difficult for me to generate repeatable results. It seemed to be most sensitive to minor disturbances. If I placed a .025" piece of aluminum under one end carefully there was no noticeable change in water level at the other end. I would constantly chase level back and forth from one side to the other. I prefer a smart level for short distances and a transit for longer distances. I took a lot of pain to rig my fuselage so that firewall vertical and horizontal was the reference point. That allows me to quickly level the fuse with a smart level on the firewall. Then perform a check by insuring that the main spar is level also. My point here is that we need to focus on repeatable results. The tool used, be it transit, water level, bubble level, smart level or chewing gum and string, is not material to the discussion in an absolute sense. I'm sure that there are others who have had great success with water levels. In my case it didn't work out. Like Mark stated in one of his recent posts, "do a little research". Then figure out what will work for you with a little experimentation. If you can get reliable results with your method, how important is it to you that I use a different method and get equally good results? On the other hand, if your method is not giving you satisfactory results, listen to others, form a hypothesis of what might work for you and test your hypothesis. We really need to get off this dead horse of you have to do it my way or you did it wrong! It consumes way too much bandwidth with no valuable information transpiring the KRnet. None of us has the time or resources to test every method of accomplishing every task in building our KRs. All we need is the one method that works for us at the time we need it. That being said, I completely understand that everything I said might be wrong for you, but it does work for me. Now does anybody have experience hanging an intercooler under a Type-IV VW? That's were I am right now and my experimentation is finding a bunch of ways that don't work for me. Please send photos of your successful installations. I'm itching to use my new found TIG skills before I forget what I learned at the SportAir class. Hope to see you all in Red Oak next month.
