    Grove Landing Gear Mod

    Marc, mentioned a proven and tested system gear system not the one you are thinking about?

    Grove Landing Gear Mod

    thanks Marc, you just saved me a lot of typing. it sounds like you want a wider stance on the gear then stock, if that is your reason to do all this engineering and work I have to say it is a waste of time and money as you will not find a more stable plane on its gear then the cozy 3 and Marc, you mentioned a proven and tested retract system? or was that a proven but not fully tested or a tested but not fully proven system?

    Grove Landing Gear Mod

    when you say Grove gear struts you mean the bent aluminum fixed gear legs?if so why would it attach to the spar?

    Berkut Kit

    we also have an SS spacer between the bearings that is .015" smaller then the bore in the casting between the bearing recesses, so even if the bearing was to fail the gear would still pivot but with some play. the bearings are still holding up even after breaking a nose fork and loosing the nose wheel. my fork and fork pivot are now made of billet 7075 alum. the stock long ez fork has been known to break even on some light long ez's.

    Berkut Kit

    Sorry Skiing comes before airplanes. i will have to check on the bearing numbers I used. and the engineering was done by a retired Space shuttle engineer and he calc'd the loads and spec'd the bearings for me. and I guess he was right as they seem to work just fine. he said the bearing could take the load and the 5/16" bolt would shear before the bearing would break but the ng 30 would be the first thing to go if the loading was exceeded. he said the bolt and bearing has about ten times the strength of the NG 30

    Long EZ Height ??

    the long ez main gear axle is at WL -22" the bottom is at WL +.9 so about 23 ". depending on the size tires used, the plans size tires are about 11.5" in diameter. so 23" + 5.75 for half the tire = 28.75"

    Berkut Kit

    the load on these bearings are not that high. taper roller will work but are big overkill I weighed the taper rollers that wilhemson uses and they are almost a pound compared to the ball bearings which weigh about the same as a quarter. the reason to change is that the bushings get worn and you get wobble on the nose gear strut and this has been known to cause wheel shimmy. The bushings do work , for awhile, the small ball bearing seem to be better as I have used them for 400 hours with out any sign of wear changing the bushings to another bearing is not worth doing if you are going to add pounds to the aircraft.

    Berkut Kit

    they do work but the ball bearings are simpler and do not have to be adjusted for preload the ball bearing have built in preload and are a lot lighter in weight. the ones I used are 5/16" id single row sealed ball bearings.

    If you do build these I would suggest that you do away with the bushings and use ball bearings as I did or a tapered roller bearing like the Wilhelmson units

    Cozy MK IV seat belt source

    the best belts for the cozy are the ones sold by ACS. http://www.aircraftspruce.com/catalog/appages/seatbelt5.php They are designed to work in our cockpits the lap belt adjustments are at the buckles and pull out from the center. this is best because there is little room to have a buckle and a separate adjuster. if the adjuster is on the side it gets caught in the cushion and is very hard to readjust. the shoulder straps tighten by pulling down and have a release strap that is pulled up to release. reasonable price and they work perfect for our planes, and no need to re invent the seat belt

    is this a complete flying plane or a project?

    Microlight 410

    it is phenolic micro balloons, it is slightly lighter then glass balloons. it was used on some of the first Ezs but because of the price is not used by most builders. does sand easier but not that much easier to make the extreme price difference worth it.

    Did they change the definition of sarcasm? even I can't see any sarcasm in his statement. what word tipped you off to the sarcasm? was it the words "Good point" or was it the word " thanks"

    Throttle quadrant - this may be cool

    They use that cheap, pull only, lawn mower cable. too many have mowed a lawn with their aircraft using those cables. and they are made for a front mounted engine.
