Yes, I will do it again as soon as my safety gear all set and solving how to remotely turn off battery power, perhaps a push solenoid to the switch will do the trick or I extend battery wire to install a 60amps relay in between.
BTW, Solo logs shows 2 barometer, where are they at ?
Thanks P2P.
Good article- thanks for the link!CreativeCOW
Check out the blood and gore in that article. It might make you think twice. Why keep the props on? Same result without props.
When you do this again, please do it on Periscope? I'd enjoy having popcorn and a soda.
Actually, that would be Stabilize mode. Starting in manual mode the motors remain at startup speed until you raise the throttle above half. But good tip regardless..Couple points:
Switching to manual mode, unless you pull the throttle stick all the way down, the motors will be commanded to run at half power because of the centering spring on the stick.
OUCH-DAMN!!Pursuant to your personal Darwinian experiment, this was posted a bit ago in the Yuneec forum.
PERSONAL SAFETY
As mentioned, please let us all watch via Periscope or...It would be useful for future training.
The patient was in v-fib, was shocked, failed to convert and died.I think I found the answer to what I am seeking.
I found this SOLO Service Manual by accident when I google, but its link is not available in 3DR website.
Google this and you will find it, its 32MB

Automatic Takeoff
Hold Fly again to initiate automatic takeoff. Solo rises to 10 feet and hovers until receiving further control inputs.
So it is 10 feet .. LOL
This Service Manual is very good for me, it explains many many things I wanted to know.
I was looking at cases where Solo flipped during auto landing as report by members here, now I want to focus on that.
So far looking at my own slow and controlled manual landing log, where I land and take off on concrete floor, I see -4 meters read by the barometer during take-off and landing just before actual ascend from floor and when about to touch down to floor.
I suspect it is a vacuum from propeller wash is what the barometer is reading.
To test this theory...LOL...I will use a landing grill like this :

And raise the grill say 1 to 1.5 meters above concrete floor.
And do full power take off MANUAL, with Solo tied down and grille weighted down too.
I want to see if the barometer will read less minus altitude compared to concrete.
Service Manual stated 2 barometer used on Solo
At Pixhawk Flight Management Unit:
- Measurement Specialties MS5611 Barometer
MS5611-01BA03–Pressure Sensors–Altimeter Pressure Sensor Modules–Measurement Specialties
.....and the same Baro unit at Pixhawk Stabilized Internal Measurement Unit
This is the minus altitude I speak of :

What do you guys think ?

P2P,
I am trying to figure out, does this minus altitude has anything to do with Solo throttling up because the auto pilot "thinks" it is descending too fast during auto-landing and causing a flip ?
If Solo can do auto-landing, it should not ever flip if the floor is even ground, even on concrete.
Solo designed goal is to be operated as least as possible in MANUAL mode, I pity those who flipped their Solo.
Besides, if I let my 12 year old daughter play with it, I want to make sure she can use AUTO as much as possible and be troublefree.
She is already eyeing on my Solo...LOL.
