"but do we realy need parachutes ;)
just look at the vid where all engines are out at 700m height (and stayed disabled till the ground):

"hi all and thanks for the kind words :)
Have updated the post to include pictures and some description of my setup.
 
I can share the code for the quadcopter if someone wants to try it with its ArduIMU.
For those who have no IMU yet and wants to…"

"free falling with minimum throttle is usually ok but try to descend from high altitude with constant, but not too low speed.
yeah, I know about propeller turbulences etc.but the fact is other projects are much more stable in such conditions."

"I see wobbling while descending is still there (I think attitude control function has some flaws) ;("

"btw. here is my axn with basic ardupilot+arduimu:

"hi,
I've just finished my quad based od the ArduIMU and Jose's source.
There is still some work to do with PID tunning but it flies quite stable even in high wind.

"your main loop is running at 100hz now.
isn't it to slow for a stable flight and what's the problem with the higher frequencies here (as far as I know most platforms work at more then 200hz and even astonishing 1khz) ?"

"hi
anyone knows what are Kp_ROLLPITCH and Ki_ROLLPITCH values and do I have to tune theme also ?

cholo"

"hi,
will it be possible to port ArduCopter code to the ArduImu ?

regards,
cholo"

"I've done radio test and it seems something is wrong with roll channel reading. I use 8ch 2.4ghz receiver and didrones ppm encoder. number of channels is set to 8.
what is wrong with that configuration ?"

"hi,
I've just finished building of my ArduIMU JJ quadcopter and start testing.
what's strange copter reacts properly for pitch and yaw but not roll.
is it normal in AP mode 2 (stabilization assist mode) ?

regards,
cholo"
