I would like to ask you, dear members of the arduplane forum, if the lenght, inner diameter and type of material of the air tube of the airspeed sensor matter in terms of affecting the precision of the sensor. I have searched all over the internet about longer air tube cables and have found nothing.
I'm building my first rc plane with Pixhawk, and my problem is that the df13 cables I have are all too short, and so I don't have enough cable and rubber tube to place the airspeed sensor as much closer to the front as possible.
Since I'm in Angola, it's preety difficult to import new parts, and I would like to know if, instead of extending the df13 cables to the sensor I was thinking if I could use a much longer tube to place the pitot much ahead in the plane. Since I can be given me some unused hospital leftover tubes, like those types usually used in blood transfusions, transporting oxigen, etc., I would like to know if those can be the solution to my problem.
I tried a sample once and even though they are a bit tougher than the original rubber tube, and it has 4mm external diameter and about 2.5mm inner diameter, and they can fit in the sensor well tight. I hope the materials and the lenght aren't a problem and wont make wrong readings, causing the plane to crash.
I'm looking forward to read about your experienced oppinion.
