You can check this on the attached screenshot. The difference is usually within a range of just a few meters. GPS signal reception is typically very good[…]

It doesn't correspond to GPS altitude. - the gps altitude in most modern gps already goes through some processing, my experience is that it is generally correct within a few meters I'm just confused as to what would be the purpose of this smoothed gps/baro altitude. There is already a widget for "thermal gain" that[…]

Instead of MSL I should have written "altitude". Removing GPS jitter is exactly whyt I want to achieve. On my cockpit(s) I have flight level and altitude fields. The first are self-explaining and a METAR based calibration works just fine here. I use them for collision avoidance and airspace compliance in higher altitudes. The latter[…]

I know its very subjective and I have heard all the pros and cons for steerable vs non steerable. I think there will so be stories where the steerable was best and the non steerable was best. I was trying to get an understanding of what the general consensus was on the comp scene where everyone has[…]

I use the Square on my "fast hand" (right) which means when im low and its a "panic" throw ill use that one, and the Beamer3 on my "slow hand" (left) which ill use if im High. My setup has 108kg and ive a 140[…]
