so in my limited, drunk testing i have done with my reluctant GF and i, i tested out disabling VPS and landing protection while it is fighting my hand that is covering all the sensors on the bottom, while my GF toggled it in the app for me..
so test one: what we did is; i had her do the auto take off with VPS and all normal protections enabled, but in sport mode, i they gently grabbed onto the aircraft as it was hovering trying to hold over the sensors and grip onto it tightly, not move it around or down or up.. once it goes full speed, i had my GF toggle VPS and landing protection off in the menus, and.,..... nothing changed it continued to fight my hands even when i lifted it up while still gripping it, once it was stationary again it started maxing out its motors. this is what i was talking about, a software looping issue, the vps and landing protection are disabled but because in a full fight while disabled it keeps trying to escape regardless..
so test 2 as a sanity check disabled VPS and landing protection before taking off, then did take off and i grabbed onto the aircraft, it actually slowed down if i was holding it slightly higher then its take off point holding it right at its take off spot where it was hovering itself ensuring all the sensors on button are cover, it was stablized at normal prop speed no maxing itself out to escape.. interesting.. so i then had my GF turn on landing protection, the aircraft didnt complain about anything then i had her turn on VPS and it whent full speed trying to escape my hand. so thats interesting it gets stuck on but not stuck off.. maybe intentional programing built in for this or maybe software is actually stuck in only 1 direction..
test number three: i decided to have my GF turn VPS and protection on (or well keep it on) and do the take off, i then grab it as normal, and try to not move it just cover the down firing sensors... then have it fight for its life, with protection then being turned off.. so we do that, its fighting still, i let go and it lifts up and drifts a bit but stabilized, then had her turn VPS and protection off i then grabbed onto the aircraft again (using my a step ladder because it was like 12 feet up) i held it exactly in place again and it was chill.. i then jumped off the ladder, and it started to wine up hard then slowed down again, it was wining hard during the free fall.. so now im curious about the IMUs, but i can't disable IMU compensation or limit them (for obvious reasons)
test 4, had VPS and protection off, did lift off let it stabilize then i grabbed it and spun around in circles, it was fighting hard... both directions, including my drunk dizzy stabling back to take off spot..
test 5 i had vps on holding aircraft as it was fighting hard but did a full forward len (to simulate it fighting head wind as hard as it can) and had my GF hold left stick full down to try to have it initiate landing, with sensors fully covered and steep angle with it fighting hard as it can to not die.. it would not land it would slow down very briefly then speed up hard again..
lessons i learned is....yes there is either a software loop or dji has blocked turning off VPS if its in a battle fighting that fight.. and no there isn't a loop or software block the other way with vps off being switched on, it just starts fighting.. the other lesson is... i'm not very sure, but, some interesting infos.. that is how my mavic acts, and reacts, can't say if that's how everyone's mavic acts and reacts or if mine is doing it right or wrong.. just what it does... |
