Also, are senders matched to specific instruments or are they readily interchangeable. I have an EMS but senders are not included and I will have to source them myself. Also any contacts or suggestions for potentiometers ( e.g. for measuring flap position). Have looked in Spruce catalogue but prices seem to vary considerably between manufacturers!

That was the first thing that occurred to me when the whole graphite causing Al corrosion was pointed out to me. The fine print, though, is that the spark plugs actually screw into steel inserts, like heli-coils. Hence the admonitions to use the anti-seize sparingly. It prevents there being excess compound which could migrate to contact with the aluminum head. glen matejcek aerobubba@earthlink.net ________________________________ Message 3 _____________________________________ Time: 06:34:04 AM PST US From: linn Walters Subject: Re: RV-List: RE: Gear legs rusting in mounts glen matejcek wrote: > >HI JR- > > > >>I know the gear legs and mounts are not aluminum but the cylinder heads >>you are screwing the spark plugs in are aluminum? >> >> > >That was the first thing that occurred to me when the whole graphite >causing Al corrosion was pointed out to me. > The only thing I've seen on the graqphite/aluminum subject was a picture of thin aluminum sheet that had been corroded through and a disc fell out.

Seems I'm always taking my Van's tailwheel apart for cleaning. After it gets dirt & dust on it after a while, it doesn't hold in the straight ahead position. Is there a zirk fitting for lubing it? Where would I get a wheel pant for it? How many hours should I get out of a stock tailwheel tire with "novice style landing/bounces"? Greg SNIP Greg, If you use my retrofit fork, the lubrication schedule doesn't change. You still need to clean and lube it periodically. Also check the pin and control arm for burrs or wear. Use your scotchbrite wheel to clean up the pin as needed. I suggest that the end of the locking pin be slightly blunt with rounded corners as opposed to perfectly round. This allows more of the flat sides of the pin to remain in contact with the control arm notch. You can (and should) observe (and understand) the operation of this while you've got the thing apart for cleaning. The pin should engage the control arm as deeply as possible. There is too much to this topic to write here, but fortunately it's common sense stuff if you simply observe how the locking pin works. If you buy a complete tailwheel unit from me you will notice that I don't use the bronze bushings that Van's uses. And there are no useless grease zerks installed. My sockets use an engineered plastic bushing that requires no lubrication. More $$$ than bronze, but worth it. HOWEVER, the steel parts must still be greased or oiled to prevent rust! AND the locking pin must still be lubed! So, it doesn't change the need to service the tailwheel, but it does make manufacturing easier mostly because it doesn't require and grease zerks. BTW, IMHO, the grease zerks aren't for greasing, they are there to lock the bronze in position and nothing else! Based on my Rocket, using my tailwheel products, I have cleaned and lubed my tailwheel exactly once in the last 150+ hours (2 years). I found no wear, and did nothing except lube it and reinstall. I'm doing a bit of a torture test on my stuff to see what happens with minimal maintenance. All I really was doing when I lubed it was to take it apart for inspection! The tailwheel tire was slightly worn, but it should last for several hundred more hours. FWIW, I fly off turf, but almost always go somewhere with pavement. So, 1/2 the landings are on either surface. I would like to make a tailwheel pant and sell it... but there simply aren't enough hours in the day! Van's tailwheel pant will fit. refer to the website below for a photo of a tailwheelpant installation. BTW, I have units in stock and ready to ship.

Cox" I would suggest that you contact Barrett, Aerosport, Performance or Mattituck on the correct distance from the flange. It needs to be consistent, the depth of insertion is also a factor, the probe's life is affected and I beg to differ that the distance is unimportant. As you increase the distance from 2 to 4 inches the combustion impulse is reduced and the read becomes more consistent. The temperature will drop as the distance increases (slightly), but what is important is the consistency of Max Temp for ROP or LOP operations. You can be assured that one inch will avoid the first tubing bend but placing it closer than the pros advise will hasten a replacement probe. You may find a recommendation of at least 2" and not more than 4". Consult the professional engine builders.
