for using them sincea while, i recommend a pyrotechnical parachute ( much faster to deploy and better luck if machine is spinning..).
I use mainly Rebelspace or Galaxy parachutes, regarding Galaxy i donot recomment the cutoff system for the Esc's but i would recommend to use a main switch 200A from Jeti models for examplen all this coupled with a 869 MHZ remote ( or on the authorised frequencies in Canada).
One mportant thing is the attachment ofthe parachute on your frame: Parachute container can be a simple support, but the cords between parachute and machine must be strong and attached on stron g spots of your machine+ have an eventual safety cable ( metal) between machine and payload in case the payload support breakcs when the parachute deploys ( very intense instant pulling..).
If you doubt about the parachute systems, here is a link to a video i made a while ago with 7 meters of rope and parachute container pointing down at the moment i did depoy the parachute...
If you need any help, do not hesitate to contact me, i will share any useful information ( safety is a matter for all of us to ensure flight authorisations...)
