Using Pixhawk 1 with latest AP and MP.
Read the wiki and the other questions here, but it seems my airspeed sensor is an oddball- no one ,mentions the 45250 5A1. Is this just another version of the same —DO sensors that seem to be the baseline sensor? Are there less noisy sensors available?
I have large noise spikes in the signal- up to 14 kph after preflight calibration. Move sensor? Tried that.Change location on external I2C strip? Tried that. Maybe isolate sensor with copper tape? What works here? Dare I use it on an auto takeoff? Looks like a stall-spin event to me.
