I have around 70 hours with the Dynon D100, and are very happy with it. It does not have to be any larger, all information is very easily read. Maybe I just havent figured it out yet,but somehow the compass is showing to much deviation. If you run a moving map along with the Dynon this is not an issue. Within the next week, if weather allows, I will pick up a CTSW in Berlin. This is equipped with the MGL Enigma. It is exiting to see if that screen is big enough for all the additional features. Reasently I have startet to fly a C172 Garmin 1000-this is a toy.You keep finding new features at least the first ten hours. This G1000 is absolutely the best EFIS I have tried, Naturally with that pricetag. Helge Andersen

AS I have special plans for my armrests it would be of great help to know how large the hole for the stick must be. Could someone inform me of the stick travel at the top of the armrests. thanks HM

Did you folks see the front hinged opus 3 in the "super cozy" thread HM

This plane is not really plans or kit build. Kai Christensen also made the design.This is his third homebuilt. The first I believe was a Jodel ,nr two was a Long Eze. I talked to him once at the Stauning fly in. It is not a Cozy but there are some similarity.The top longerons is lowered,the canopy he has pulled over a positive mold(and it is really great).It has a center stick,and he has altered the C of G to avoid ballast when flying solo. After this picture was taken he has added an angle of attack indicator. Believe it or not --it has got new paint. Right there is a gullwing for the rear seat. I heard it was built within one year.

What Burt would do?????????? The most common mod. I think concerns the canopy. I noticed a 3 place in Denmark ,where the view has gained and the access has become better so has the shoulder space. www.kzclub.dk/Rally2000DS/planes/index_8.htm Seems like there is some tension in the fuselage side above the landing gear.

You can find more on MT props on:www.mt-propeller.com Helge

Variable pitch has been used by Uli Wolters in Germany where a lot of nice props are being manufactured. Hope this works 1. time tried Helgeusers.sisna.com/dbmonk/nl24.htm

What Helge in Denmark is doing? I am suggesting you think twice before puring biodiesel on the strakes, it might get rancid in the summerheat before the economic diesel engine has emptied the tanks. I am still going for the D5.I have also considered to leave the reduction gear,but dicided to use a cogged belt reduction. Then I get the propellorshaft elevated to where it belongs,and I get the bearings that I know will hold the prop. I am not sure the crankshaft has got the pressure bearings needed for the longitudinal force. Also I believe I need max power (4000 rpm ) for takeoff on my grass runway. No4 if you want to use the V10 I suggest you build the main spar with a big -O- in the middle.This you can put your engine into and get your balance right.Thats what I would have done if it was the only way to fit the desired diesel. Hilsen Helge

I forgot to mention 23.963 to and included 23.999 just to get it complete. Cheers HA

In Denmark we have adopted some of the US regulations. Concerning the fuel system it must comply with FAR 23.1091 to and included 23.1105 for fixed wing aeroplanes and motorgliders. Sorry I can´t set up a link.Somehow I dont have any succes trying to find it on the net. Cheers HA

In My former life in the offshore buisness we used titanium in a plant for preparing seawater to be injected into the oilreservoir. Exept for some none fireproof plastictypes and gold it was the only material that was not corroded by sodium hypochloride (I think it was) I cant imagine that it would corrode when used in an aeroplane. Great material; light as aluminum, strong as steel, shiny like chrome.For welding you would need a special chamber.I never had the welding certificat for titanium,but you sure need to be skilled to do the job.For bolting must be used either titanium bolts or insulated bolts.(nylon washers and tube) HM

You might want to check this www.rospeller-aero.com . This is a german manufacturer.Claimed to be for rotax and others,they got diameters up to 70`.It might work with other engines at a price about 4000$. HM

I have been offered some composite parts which have been stored for some time. Now I would like to know if there is anyway to tell if the parts have been weakened by sunlight. Advise be appriciated HM

While I was working offshore on the oil installations in the north sea we started to use fibercast pipes from Amron for seawater service. In this line of business Quality is rated very high.After assambling pipes with epoxy, Heat treatment was a must before pressure test could be performed.There were no time limit between doing the assambly and the heat treatement. There were never problems with the quality.I believe when in doubt do the heat thing.My entire plane will be heated Helge

Sure retract is very tempting. I to was considering a solution where the retract was fixed like original.Could look a bit like the Velocity. On the other hand ,using the Infinity system you could redundant the original fix points and save some weight. As for reinfocrcements would`nt Infinity supply the data needed ? Regards Helge
