    Yes I can confirm that. The classic used a short-and-fat one-piece aileron, whereas the XS uses a long and thin component construed out of two foam cores that need bonding prior to layup.

    That should read "constructed" .........I'm having trouble with my smell checker :-( On 23/02/2013 11:28, nigel_graham@m-tecque.co.uk wrote: > Yes I can confirm that. > The classic used a short-and-fat one-piece aileron, whereas the XS > uses a long and thin component construed out of two foam cores that > need bonding prior to layup. > > On 22/02/2013 19:00, spcialeffects wrote: >> <spcialeffects@aol.com> >> >> Could someone just confirm for me if what I am thinking is correct >> please.

    Subject: Re: Damping Grease
    Kelvin, I did not see an answer to your question, >From my standpoint as an owner and tech support for Europa, I find the O ring solution is marvelous. My plastic disc stays quite clean, negating the need for the sticky grease. However, DO NOT USE THE GREASE DZERK FOR GREASING THE FORK SPINDLE. Reason for this is a grease gun (even a hand one) applies the grease under strong pressure. If you grease until the new grease comes out of the top, rest assured it is blowing past the O ring also. Grease on the plastic plate of course eliminates the friction plates effectiveness as it is now lubricated with slippery grease. I use Aeroshell 22 for my spindle and wheel bearings, but any HIGH VISCOSITY bearing grease is OK. The spindle sets in the housing with a spacer between brass bearings so only use a film of grease on the shaft and put a small amount in the recess. Do not pack it full, as it isn't needed. Make sure the seal and seat are clean and reinstall. This shaft doesn't turn that much, and frankly I am more worried about corrosion in wet environments. Personally, I place some weight on my rear tie down/stab tubes to hold the nose off the ground and I remove my nose gear fork every annual inspection and apply a bit of grease, it also allows a proper repack of the wheel bearings, as well as inspection of the fork, and the shaft. I clean my disk annually and at the 5 year point I install a new one. Check the pin is still secure. Reassemble and set the steering force for about 16-21 pounds of pull at the rear of the tire. We use a scale and a bit of safety wire loop to go from the axel bolt back around the tire rear surface. Then hook our scale up and pull. Note there are two frictions. The first is the torque to break the friction, then there is the rotational torque. 21 pounds for the breakout and no less than going around is what I set the friction when new. Then I adjust after initial taxi tests. On grass, 16 pounds breakout is about right for me, but on asphalt on a warm day, you may encounter shimmy if you land and lower the nose immediately. (You can hold the nose off until 35 Knots quite easily, and solve the shimmy problem unless your dampener is quite loose.) If you choose to use the sticky grease for the shaft as well as the shimmy dampener plate, that is OK as the manufacturer of the grease insists it is a lubricant also. I ordered some grease from them a while ago and they failed to ship to the US, so I am trying to acquire some from a retailer in a small quantity for those clients that use or wanted such a grease. Best Regards, Bud Yerly Tech Support ----- Original Message ----- From: Kelvin Weston<mailto:kelv@kdweston.biz> To: europa-list@matronics.com<mailto:europa-list@matronics.com> Sent: Wednesday, February 20, 2013 3:11 PM Subject: Europa-List: Re: Damping Grease <kelv@kdweston.biz<mailto:kelv@kdweston.biz>> All I am about to assemble my nose gear and shimmy damper and intend purchasing some of the damping grease from Newgateonline as recommended. I can find no mention of this damping grease in any Europa documentation or indeed on the Europa Club website so I'm assuming it has come about from experience during operations. I did find some old threads on this forum which provided some background to it's use. However, before I rush out and purchase, I have a few questions: Mod 59 installed an O ring to prevent grease getting onto the friction plate but am I right in thinking that this damping grease is used between the shimmy damper friction plate and the nose leg bearing housing? Also, have owners used it to fill the fork spindle bearing housing via the grease nipple? The build manual has no mention of the grease to use in the spindle housing, so I guess some general purpose Aeroshell No 5 would be OK? Many thanks. -------- Regards Kelv Weston Kit 497 kelv@kdweston.biz<mailto:kelv@kdweston.biz> Read this topic online here: http://forums.matronics.com/viewtopic.php?p=394691#394691<http://forums .matronics.com/viewtopic.php?p=394691#394691> http://www.matronics.com/Navigator?Europa-List<http://www.matronics.com/N avigator?Europa-List> http://www.matronics.com/contribution<http://www.matronics.com/contributi on>

    Thanks Bud Good advice, as always. I shall assemble the friction plate dry, without the damping grease initially and install the fork as you describe. If shimmy becomes a problem in use, I can always add the damping grease later. Thanks again. -------- Regards Kelv Weston Kit 497 kelv@kdweston.biz Read this topic online here: http://forums.matronics.com/viewtopic.php?p=394881#394881

    Hi! Kevin, For my experiences:- If you have a trike wheel fairing you may not get to experience two examples of wheel shimmy and still have a wheel fairing to bother about!
