Simple 'L' shaped, aluminium pitot heads available either as pitot only or pitot static, both have flange mounting to aid underwing fitting. #15144 Made in USA
The combined pitot-static looks just like the photo and appears that it should work fine for its intended application, but purchasers should beware that the welds are fairly ugly. They're fairly large, not symmetrical, and the heat-affected zone wasn't cleaned up. One of the welds is fairly close (1/4 behind) the single static port hole. Again, the port should work just fine, but I was expected a better fit and finish - every time I look at it, I want to grind the weld off and redo it (saving that effort was the entire point of buying this assembly). It'd be nice if they offered an option of buying the parts (two bent tubes, endcap, baseplate) unassembled, so that end users could put them together in a more aesthetically pleasing manner. For a low-stress application like this, I'm pretty sure the tubes could be held in place in the baseplate using industrial adhesive, and there was probably no need at all for the two tubes to be welded together at the bottom.

At last - a simple, inexpensive, good-quality pitot-static head for homebuilts! Thank you AC-S!

This particular design doesnt work well with the 230 airfoil. It doesnt seem to be low enough to get out of disturbed air. I get erratic and unreliable airspeed readings. Im going to switch to a mast type coming straight out of the leading edge.
Ответ:The distance from the flange mount to the L is fixed. The vendor has no record of any max airspeed data. It is an experimental part intended for small general aviation aircraft. No record of any failures due to airspeed.
Ответ:The four mounting holes are drilled and countersunk to use 1/8" diameter AN426 100* flush head rivets. The mounting holes are 1.1" center hole diameter.
