Another unusual feature of the STATEK double probe seems (from the picture) to be a rather long TE side tube which appears to about 18cm if the picture is to scale. A double TE/Static probe would suit me better than a triple probe and it would be helpful to know whether or not this model works well for both functions. BTW my email above no longer works. Thanks in advance for any help.

I have had the older, usual TE (1 way) fin probe on a DG400 for many years with no problems (upgraded to an ILEC probe with 2 small holes instead of the original 4 slotted). I now have the Triple way on my 600, and it's already showing problems: there are some small O-Rings which have started deteriorating and are a ... to replace. The probe itself is available in black carbon fibre, or in aluminum: I strongly suggest the latter. The composite ones have soon cracked (nearly invisible cracks) near the plug, giving problems with vario reading. If you are choosing within the options for a new glider, I'd have it with two separate connectors for TE and Ptot, and would be happy with fuselage statics. From a reliability point of view.

Yes I should have been more clear - I am thinking about equipment for a new glider. I have had the triple probes on 2 previous gliders without too much problems from the O rings. I have variously used a little PTFE or silicone dry lubricant on the rings of the probe itself as it is noticeable that when the probe gets stiffer to insert you get some rubber marks on it from the internal rings. I wonder if there is any better way of preserving the O rings?

In the tail fin we have two adapters. The lower one is for total pressure with a one hose connection in the fin only. The upper one is a multi probe adaptor having three hose connections in the fin. We use the STR/ST1 probe for Total pressure (and not just the extending adapter part).We use the STATEK/DN/UN for Static and TE. This is a special design. You can find detailed info at http://home.wxs.nl/~kpt9/esa-systems.htm . This one of the subpages of my home page. Contact me in private if you like to know more.

I wonder if there is any better way of preserving the O rings? I've always used a hardware store silicone grease by GE on mine. The ones on the ASW 20 C were still good when I sold it 11 years; the ones on my ASH 26 E are still good after 9 years. We have 100+ degree summers and sub-freezing winters. Good O rings should last indefinitely as long as they aren't used "dry", as they do in much more severe conditions, like shock absorbers. -- ----- change "netto" to "net" to email me directly Eric Greenwell Washington State USA Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AirTalk.org Forum Index -> Sailplanes All times are GMT Page 1 of 1   Jump to: Select a forum Aviation----------------alt.aviationAviation safety EnhancementPlanes, gliders and flying in AustraliaAviation et pilotage (Français)rec.aviationAviation (Aerobatics)Hot air, gas balloons and airshipsHang-gliding, paragliding, foot-launched flightAircraft Design & BuildingInstrument Flight RulesAviation (Classifieds)Military AircraftNaval AviationAviation (Miscellaneous Topics)Owning AirplanesAviators (General Discussions)Aviation related productsAircraft RestorationHelicopters and rotary wing aircraftsFlight SimulationSailplanesAviation (Students)Light aircraftFlying related activities in the UK Airports----------------alt.airportsEdinburgh Airport Glasgow Airport Humberside Airport Luton Airport Aberdeen Airport Glasgow Prestwick Airport  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
