I'd like to add a safety parachute to the Arducopter !! help me decide....
As part of the project is to use an expensive DSLR on the copter,
My GF said i must have some kind of emergency parachute... after joking at it, i thought deeper -
I'd rather feel much safer having a parachute as backup to all electronics (even though i plan on 6 or 8 motors)
Just imagine an emergency button that will immediately turn off all motors and shoot a parachute.
as parachute takes some time to open (=some free fall height), the benefits are sure and obvious for a 100m fall.
but if i'm around 5m above ground, (which can still be nasty to the DSLR) - would i have enough "falling time" to open the parachute and having enough braking force ?
think i better make one by myself ? is it rather simple as cutting and connecting wires to a cloth,
or it is more complex design that i could hardly achieve and i better get a ready one ?
i came across this as the only parachute i could find:
It looks sturdy and well balanced & stuff... it's totally affordable !
they say the 40" version has 7KG resistance. i'm safe on this side, i dont want a much bigger one.
how about the opening technique ?
i could stuff it in a small plastic tube attached to the top of the dome, using a small solenoid or servo to kick it out...
how do i ensure it opens reliably ? i guess it depends on the folding inside the storage tube...
