Marc Zeitlin Posted September 11, 2008 Share Posted September 11, 2008 I can't answer about the 1/4" CLT's, however my guess is that they are beefed up for the cozy.Some folks believe that they're making their planes safer by using thicker lift tabs on a COZY MKIV, but all they're actually doing is making their plane marginally heavier. The 1/8" lift tabs are more than adequate - none have ever failed. Quote Marc J.

Rick I'm not quite sure I understand the question, however (at least for the Long-EZ) you will need 5 NC-3 and 2 NC-3A. !!!!! However I do see I made some mistakes. Here is a revised drawing.

mfryer Posted October 7, 2008 Author Share Posted October 7, 2008 The canard glassing is finished (except the elevators and swooshy tips). I made a frustrating goof. The Roncz plans call for a 1" wide peel ply on the trailing edge. I later (too much later) realized this should have only been applied to 1/2" of the trailing edge. Some considerable damage was inflicted to the top foam to remove the peel ply. After sleeping on the problem (no, I did not actually sleep on the canard) I masked 1/2" of the bottom trailing edge glass and filled in the damage with micro. All in all the repair went well. I will begin work on the elevators when some materials arrive from ACS and McMaster Carr. http://flyingbackward.blogspot.com/ Flying Backward Quote Link to comment Share on other sites More sharing options...
JTest Posted October 7, 2008 Share Posted October 7, 2008 G'day Looks pretty good. Thanks for the 1/2" pointer. I would have made the same mistake; only mine would have been 2". I will be putting mine together next month. I have spent the last three months moving hangers and setting back-up the shop. My wife and kids got four weeks for a trip to Australia and Fiji. Looks good and thanks again for the pointer. Still looks good. Jeff Quote Link to comment Share on other sites More sharing options...

Looks good and thanks again for the pointer. Still looks good. Jeff Before you do it, take a good look at the pictures at the back of the chapter, and at the drawing in the plans. All you are trying to do is ensure that you have a glass-to-glass bond that is at least 1/2" wide at the trailing edge of the canard. Mine turned out with a little dip on the top surface, but I got a good glass-to-glass bond. After I installed the elevators I filled in the dip with micro and sanded to contour.

I agree that a little over 1/2" would be fine and a little dip is easy to fill. However the full inch of peel ply was very difficult to remove and caused unnecessary damage to the foam. One other suggestion.... I ordered 10 extra yards of 3" uni tape for the spars and nearly used all of it. Also as usuall the layups took a very long time for me to complete. Defiantly make sure that you have enough material and time before you start and begin early in the day and make sure you don't get tired or rushed. From what I have read, and this makes sense, the canard and especially the elevators require a very good quality workmanship. Quote Link to comment Share on other sites More sharing options...
mfryer Posted November 11, 2008 Author Share Posted November 11, 2008 Hey all. It's been a while since I posted an update here, so.... The elevators are now fully glassed. I am getting ready to order some parts from the CGs soon so I will be able to mount them (no! the elevators you fool!) . I have also cleaned up and painted a used worm drive assembly I purchased from a fellow Canard Zone member (thanks!). http://flyingbackward.blogspot.com/ Flying Backward Quote Link to comment Share on other sites More sharing options...

mfryer Posted January 16, 2009 Author Share Posted January 16, 2009 the 5.00 -5 have been used by some but they are a bit big for a long ez they are heavy and expensive. they require a big set of wheel pants. the 3.40 tire were used on the early Varieze's but not used much anymore. the tire most use on a long ez and vari eze's is the 4.00-11.00 by 5 lamb tire, lamb sold out to Chin shin a few years ago who still makes the same tire. as you can see they are a bit cheaper then the 500- 5's. about 5 times less. you may want to check with Matco to find out which wheels you have, there is a difference in the wheels used with the different tires. the tube valve stem is in a different position. On the front we use the 2.80/2.50 by 4 tail wheel tire about an 8" diameter. they cost more the the main tires. http://www.aircraftspruce.com/catalog/lgpages/tailwheeltires.php http://www.aircraftspruce.com/catalog/lgpages/lambtires_tubes.php I need to order some sundries from ACS (brushes, micro, etc). I hate to order just a couple small items because the shipping costs start to add up. So I am going to order my smaller replacement tires as well. They are available in 6 and 8 ply, which are recomended? Quote Link to comment Share on other sites More sharing options...
mfryer Posted February 15, 2009 Author Share Posted February 15, 2009 Other the last few months I have been fiddling around with the canard. Finally I have decided to put it away for a while and start the nose gear and nose. Today I trial fitted the worm gear assy. ng-8 disks and ng-30 plates. I also cut, bent, welded and painted a crank. More to come when I order the nose gear strut, ng-6 and ng-15 castings. Cozy girrrl nose wheel is en rout....

mfryer Posted June 17, 2009 Author Share Posted June 17, 2009 Well today seems to be the day for Long-EZ builders to show there noses.... This weekend my brother assisted me with the shaping of my nose.... Perhaps because my real nose is already somewhat large, I don't feel the need to compensate with a really large aircraft nose. I did however extend the nose about 4" over what the plans call for, unfortunately this did not leave space to move the battery forward so this minor modification is really only cosmetic. I do like the way the nose shape is turning out. I just hope I don't have to kick myself later for not allowing for more forward weight. Of course there are more images and details on my blog http://www.flyingbackward.blogspot.com/ Quote Link to comment Share on other sites More sharing options...
TMann Posted June 17, 2009 Share Posted June 17, 2009 my brother assisted me with the shaping of my nose....Yeah ..... my brother helped me with my nose ....... when we were kids. It's sort of off to one side of my face as a result. Excellent progress PTM! It's amazing to me how many Long-EZs are currently at this same stage. That pretty much speaks well of the design. 30 years later and folks are still starting Long projects (..... is that a pun? ) Quote T Mann - Loooong-EZ/20B Infinity R/G Chpts 18 Velocity/RG N951TM Mann's Airplane Factory We add rocket's to everything! 4, 5, 6, 7, 8. 9, 10, 14, 19, 20 Done Link to comment Share on other sites More sharing options...

Kinnerhatz Posted June 17, 2009 Share Posted June 17, 2009 Looks great! It's refreshing to see such a stock build. Is that urethane foam on the nose? Some people have trouble with the long-term durability of that stuff. Quote Link to comment Share on other sites More sharing options...

Some people have trouble with the long-term durability of that stuff. Yes it is. That is the first I have heard about duribility problems (cringe thinking there may be a CP mention of it). Still That doesn't supprise me as the stuff is quite crumbly. If I were to do this again I might consider another type of foam. Quite easy to shape though.

Hey Martin, If you really would like to do all that work again, I have some extra blue foam(wing foam), if you'd like I could bring enough with me for that nose job when I come to Arlington. It's just taking up extra space in my shed, it's yours if you want it. I can toss it in the back of my truck, I'll charge you a Pepsi for the handling and shipping.

Bruce Thanks, but I think I will take my chances with the urethane. It was fun shapping the nose and canopy frame, but not so fun that I would do it again. If you do come up to Arlington, i'll throw in the Pepsi for free, I understand the some of the local Olympia EAA folks will have an RV or two with ice you can keep it cool in.
