    The DJM pitot tube is well made and relatively easy to install. It’s not made to be flown in icing conditions – like the rest of my airplane (RV4). There are a couple things to consider before buying. Once the hole is cut in the wing skin, the pitot tube needs to slide into that hole from the top, which it does very nicely thanks to it’s small profile on the bottom. However, to make that happen, you will need an opening in your forward wing spar web adjacent to where you cut your hole. The top portion of the pitot (where the mounting flange is welded) needs to fit through that spar web opening, with the nose of the pitot pointing down and through the hole you’ve cut. If you don’t have a lightening hole in your wing spar web, you will need to mount the pitot tube further aft to allow it to be inserted.

    I made a doubler that was riveted on inside of the wing skin with a bent angle on one side that was also riveted (cherry max) to a rib. It doesn’t come with a cut out template, so you’ll have to make your own. A small portion of the tube protrudes through the top of the welded on mounting flange, and you can use this to make an accurate cut out template. Punch a small hole in a piece of paper for the plastic tube to go through and then press the top of the tube onto the paper to make an impression of the tube. Draw this impression on the paper and then cut it out with an exacto knife to make your template. I then took a piece of scrap aluminum and drew the template onto it. Then cut out the hole for the tube carefully to make sure I had a close, tight fit. I clamped this aluminum template on the pitot tube flange – at the work bench – and drilled 4 1/8” holes for mounting the pitot tube. This aluminum template is then used to mark the cut out hole in the wing skin, and after that is done, and the pitot tube fits it nicely, the template is taped back on the bottom of the wing skin and doubler if you are using one, and the four mounting holes are drilled 1/8” (#30). The pitot tube is then in inserted from above, with the doubler in place if you are using one, for a trial fit. Clecoe it in place and enlarge to mounting holes to whatever size fastener you will be using. The pitot tube is pretty light so I used #8 structural machine screws because I could dimple the skin and machine counter sink the pitot flange for flush screws.

    I think it took me longer to write this review than it did to install the DJM tube!
