I have a Phantom 4 and without building an entirely new drone, what motors can I put on it to lift about 5-8 lbs? I'll have to keep the 9.5" props (may be able to use 10" b/c of the small size of the frame. I'm doing some cargo drops and need to lift a little more than what it can lift now (about 2-2.5 lbs). Would I have to change the ESC's, too? Any other considerations?Thank you.See More
"you could easily do this with an arduino [nano/micro/whatever] + SD reader + MPL3115A2. If you wanted to also beam down the data in realtime you could also use a set of radios. Total cost [if buying from ebay] would be about 10 bucks.…"
"all you need to do is look at the logs.... read the alt vs the time line.
But rather than trying to measure decent 'rates' all that is really important is the final Z vib (and x and y to a lesser degree) shock value as it hits the…"
"If you're willing to connect a Raspberry Pi to the Telem2 port and read the MAVLink messages using dronekit (this requires a little programming), then you can record the changing pressure vs. time, which will give a pretty accurate descent rate…"
I'm doing some testing on parachutes and want to record descent rate. Is there a way to do this with say, a cube, without going to a pitot tube? I would think that the angular descent of a parachute would not give accurate descent rate (or would it?) due to the lateral motion. Does the cube have an RTC to record the samples by time along with the other sensors, so I could calculate speed over time? How about an add-on to a cube (a la arduino shield) to do the airspeed descent rate. I'm…See More
