Posted 5 Oct 2012 I have an Avid Mark 4 STOL which I bought as a project. It has not flown. Am in process of recovering wings. I am not crazy about the pitot system on this bird. I like the look of the one Spruce has for about $150.00. Anyone have any suggestions ? The pitot tube on the plane now is just aluminum tube with a pipe fitting and a slight flare pointing into airflow. Bill Share this post Link to post Share on other sites

THe main issue is the static port placement, as avid has you have an open filtered tube under the dash. The accuracy is highly suspect! Personally, I would invest my resources in a decent static port mounted on the side of the cowling. John Miller did that, hopefully he will chime in here and give his .02 attached is a pic of his set up. I use the airspeed needle as apoint of refernce but don't actually believe the number it's pointing at, must be a government needle Good Luck, Bryce Edited 5 Oct 2012 by BryceKat Share this post Link to post Share on other sites

Posted 7 Oct 2012 Thanks Bryce, I went ahead and ordered one of those static ports from Spruce. I also ordered the experimental pitot tube from Spruce. I like the looks of it and it will be an easy install (I think) Had to make a snap decision as I want to get the wings covered before Oct 15. Thanks for the help.
