Anticept Posted February 23, 2023 Report Share Posted February 23, 2023 I've seen them installed slightly off alignment, but yes the air dam is supposed to be facing forward and aligned to the longitudinal axis of the aircraft. Quote Link to comment Share on other sites More sharing options...
Big Flapper Posted February 23, 2023 Report Share Posted February 23, 2023 Thanks, I have been thinking about straightening mine and then test flying to see if it makes any difference. Quote Link to comment Share on other sites More sharing options...
swedishCT Posted February 23, 2023 Author Report Share Posted February 23, 2023 Jeff, that's exactly what I needed. Your the best! If it's no to much to mask, could you please send me the following as well: Outerdiameter of the port, Inner diameter of the hole the hight of the airdamm And the width of the airdamm Quote Link to comment Share on other sites More sharing options...

I agree that the air dam should be forward, but I have seen installed both fore and aft from the factory. Quote Link to comment Share on other sites More sharing options...

Having it aft would completely screw with the static readings, that's weird! Quote Link to comment Share on other sites More sharing options...

Or you could just purchase one from FD. See attached picture for part number. Quote Link to comment Share on other sites More sharing options...
swedishCT Posted February 23, 2023 Author Report Share Posted February 23, 2023 Thx alot Bigf As i metioned earlier on, I've tried getting one directly from FD, and the answer I received about 1 week ago was that they do not know when they can get me the parts and they can't give me an exact price of the parts due to price increase world wide etc etc. On 2/17/2023 at 5:52 PM, swedishCT said: Hey Anticept, thx for the info! Thing is that I've been in contact with FD and they do not know when they can provide me with the parts. Do you have any picture of the static port?

swedishCT Posted February 24, 2023 Author Report Share Posted February 24, 2023 So here is the final result, thx a lot for all the help! Quote Link to comment Share on other sites More sharing options...

Anticept Posted February 24, 2023 Report Share Posted February 24, 2023 I don't think there is actually any crosshatching on them. There isn't on mine. I think the one post that showed it was an illusion or just a one off on that one. Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted February 24, 2023 Report Share Posted February 24, 2023 I have two in the shop right now, and neither have the crosshatching. Quote Link to comment Share on other sites More sharing options...
Anticept Posted February 24, 2023 Report Share Posted February 24, 2023 If anything that would just make the airflow more tubulent anyways which you don't want on a static port. Quote Link to comment Share on other sites More sharing options...
Towner Posted February 24, 2023 Report Share Posted February 24, 2023 Not sure why mine has the cross hatching. In someone else’s picture, it has the sticker over the area and I wonder if the sticker is covering the hatching? Quote Link to comment Share on other sites More sharing options...
swedishCT Posted February 25, 2023 Author Report Share Posted February 25, 2023 Okey, then here comes one without the hatch, ill post some picture latter on of the finished part Quote Link to comment Share on other sites More sharing options...

Anticept Posted February 27, 2023 Report Share Posted February 27, 2023 Sand the face of it as smooth as you reasonably can, including the air dam. Quote Link to comment Share on other sites More sharing options...

I'd like to keep that in my back pocket for a rainy day. Beautiful print BTW, is that resin? If so it probably won't require additional sanding/smoothing.

swedishCT Posted February 27, 2023 Author Report Share Posted February 27, 2023 Ofcourse! I'll share the stl! Yes, it's resin printed on a formlabs 3 using their though resin, it's so smooth that sanding it would not make that much of a difference, perhaps the only part I would have to file/sand down would be the bumps from the supports on the leading edge of the airdam.

swedishCT Posted February 27, 2023 Author Report Share Posted February 27, 2023 So here are the stl-files the outer thread of the static port is m16x1,5 the inner thread of the static port is 1/8" BSP the inner thread of the nut is also m16x1,5 static port nut m16x1,5 v1.stlstatic port m16x1,5 v1.stl Quote Link to comment Share on other sites More sharing options...
Anticept Posted February 27, 2023 Report Share Posted February 27, 2023 If it was resin printed then nevermind on sanding. My last suggestion is take some used engine oil and brush it on it. This is to make sure it doesn't turn to a liquid mess. The bellies get a bit of oil all the time. Quote Link to comment Share on other sites More sharing options...

I have a resin printer also as well as FDM. A tip I learned for FDM printers: If you need something smooth and still precise, brush on some UV cured resin to fill in layer lines, then hit it with a UV light to cure it. Then you can sand it very smooth with some fine sandpaper without losing dimensions. Quote Link to comment Share on other sites More sharing options...
swedishCT Posted February 28, 2023 Author Report Share Posted February 28, 2023 Thx for the heads-up anticept, however the resin I used has great chemical resistance and is not affected by oil, gasoline, ethanol, diesel etc. https://support.formlabs.com/s/article/Solvent-Compatibility?language=en_US Flyingmonkey, that's an awesome way to get things super smooth. However, I've pretty much stopped using my FDM printers and soly use my resin or sintering printer since the result are that much better, I find that the resins out there have such great properties that one can almost 3d print anything, one just has to use the right resin and printer. Once again thanks for all the support and happy/safe flying! Quote Link to comment Share on other sites More sharing options...

Once again thanks for all the support and happy/safe flying! Yeah, my FDM is a dust collector most of the time too. The only advantage it has is that the PLA & ABS used in FDM are a little more durable than resin, which tends to be a little brittle. I think both with become brittle and break down over time exposed to UV light, so I'd definitely check your homemade static port carefully at each annual. The good news is you can print a new one in a couple of hours! Thanks again, this is an awesome bit of engineering. Quote Link to comment Share on other sites More sharing options...
sandpiper Posted March 6, 2023 Report Share Posted March 6, 2023 A pitot tube like yours pulls out. You may need to carefully work it out with a pair of pliers. I wrapped mine with some duct tape and also used it on the jaws of the pliers. The pitot has a quick disconnect to separate it from the pitot tubing.
