Multirotor parachute tutorial

So a little while ago I created a parachute recovery system for my Quadcopter. It works so well that I've decided to make a quick tutorial on how to make one, It really is very simple.
Here's the tutorial:

very cool unialfred!

if i may make a suggestion, you might want to look at chutes with less shroud lines...

more expensive, granted, but think about the equipment you're protecting

trust me, there's nothing more exciting than to see your chute deploy in a big knot and watch thousands of dollars worth of hardware falling to earth at terminal velocity

i used to use those chutes for UAV helicopters and they worked well - less shroud lines = less chance of entanglement

also, i'd think about rubber-banding your shroud lines together so they don't become tangled in the container from normal use/vibration before you deploy

this was my first test with a chute something like yours - later i changed to the rocketman chutes because of deployment failures and refined the system...

pretty cool - nice and professional looking anyway
unfortunately, after you get done mounting that i don't think you'd have room to mount anything worth protecting doesn't look too light

what is very interesting to me though is how fast that chute is inflating - i could never do that using the packing method they are

You might also want to look at the price tag :P $499, no thanks. I'll stick with my <$10 parachute system which works just fine
With eight lines it works just fine, Haven't had a single line tangle yet or mallfunction. I've even tested opening it while at different angles and fully inverted, It still opens just fine. The size is the only problem I have ,It weighs a little over 150 grams so isn't really much extra weight, especially if you were putting it on a hexa or something. I think If I had a smaller tupperware container I would be able to pack the parachute down smaller but then you run the risk of the chute getting wedged.

you could use phenolic or carbon tubing - both are light and readily available from the rocketry industry. this would allow you to pack the chute much tighter into a smaller space

the problem then becomes deployment - you could use a spring like they did (heavy), or a small explosive charge (FF black powder) and an electric match - that is what i did in the heli recovery test video. all this is very inexpensive. also take a look at different materials maybe and see if what you're using is the thinnest and lightest

i didn't realize their systems cost $500 clams - that is insane - you could build a replica for probably less than $50 using all off-the-shelf parts and probably less using the material you're using

I have to agree $500 is a bit high for that system

For that price I would expect a fanfare and some fireworks on deployment and a waiting group of firemen to catch my copter should disaster strike.... I like the $10 version.
