BG914785312 No need to reassign. Just configure it in inav output card

skyfox60 Even in a ( felt ) calm position you will not achieve an constant zero indication. There is allways a little bit indicaated around zero. These pressure sensors are very sensitive and on low speeds ( which is around zero ) it is nearly impossible to get a stabler and correct indication. This failure becomes lower and lower at more and more raising speeds. So dont worry about that. Just fly and check the speeds indicated. On a really calm day ( very early or later in the early evening, your indicated airspeed and your GPS ground speed should more or less match. With talwind flying your GPS speed ( Ground speed is the higher one, and with headwind, your indicated airspeed is the higher one. Make sure to determine your stall speed, too. That is only dependent on and related to the airspeed, and not on the Ground ( GPS ) speed. You will see, the 4525 works perfectly, once your aircraft has resonable speed achieved.

Arnror It's a dipole, so it doesn't matter. Just order it in the same way as the TX antenna.
