I used an APM 2.5 and know that I need a case to keep light and wind off the barometer on the APM.  But does the PX4 need a case or a cover to help it?  The reason I ask, is I'm having a hell of time…Continue

Hi Richard,

My apologies for not getting back to you sooner.

Unfortunately I have been very busy lately looking for contract work to supplement my retirement income and helping to support the ArduRover User Group.

Since you work in Davie during the week, maybe we could meet up at my place at the end of one of your work days?
