We are now live at www.skycat.pro. The development project continues, and updates are added to this blog in random intervals.
We have parachutes launchers available in many weight ranges; optimal 1 - 6 kg and these could be extended with higher impact level up to 11 kg. For larger up to 23 kg multicopters we have XL - series with pilot chute principle.
For those who wants to digest all information available of products, we have left this blog as it is. This blog follows closely main steps we have gone through while developing parachute launcher. Blog might feel like Do It Yourself kind and to be honest, in the beginning it was.
After hundreds of hours thinking, designing, prototyping and testing our patent pending launcher turned to be the most reliable parachute launcher for professional use. We have searched all possible boundaries of technology and from this blog you'll find results of these successful tests but also not so successful tests.
You never know where The final limit of technology is without experiencing it. That's the reason why we have done tests for scenarios which might not be even realistic on flight.
For production versions of Skycat we could proudly to say that we have experienced zero mishaps, never failed a single eject and parachute has deployed every time. This includes rescue scenarios with every imaginable scenario copter could face in air. Check this out as one sample of our test sessions!
Skycat parachute launcher has been tested beyond all imaginable abuses copter possibly could experience in flight. We have sink it to water, it has been heated hours to 90°C and exposed to extensive moisture, we have frosted, defrosted and frosted it again, it has been in mud and snow and still it has worked. Same overshooting tests we have done also for electronics. This is not promise you can use our products outside of submarine but we have tested it so :)
Fly safe - Let's keep our copters flying!

Henri, great tests! very interesting!
The secret is to fly at high altitudes because if you stay at medium heights the parachute won't open and it will cause damage ;)
By the way, how are you going to eject the drogue? Spring?
That really is tall, probably too tall.
I could provide 3cm carbon fibre tubing and perhaps larger although it would probably be easier to just get a sample for $25 from these guys and they seem to have up to 4cm diameter.
updates: Here is series of images as pdf of packing the main chute. Today I ordered one possible pilot chute more. Hopefully this third version is suitable. This is 1.8m2 chute from Opale Paramodels. Main chute feels good and therefore I trust this also.
I think one biggest risk we have is that pilot chute tangles before it opens the main chute. I believe pilot chute has good change to open because it is pushed out. Opening is only matter of luck if copter is spinning or is upside down. Anyway, this pilot chute is so big that it has good change to even turn copter and pull main chute out. If only pilot chute opens will speed be for 10kg copter according to descent rate calculator about 10.5 meters/s. It is way better than free fall.
@Randy: Is it possible to have automated deploy for high risk copter mode so that APM does decisions before operator sees something going wrong? Or does it have capability to wait and try to turn copter to best possible deploy orientation until last possible deploy altitude?
For all viewers: We must be proactive in safety of these heavy flying machines. Yesterday accident caused death of a pilot is again one sample what might happen if everything goes wrong. In this case pilot was flying 3D and none safety system couldn't prevent hit but same result is very possible with any large camera copter.
It's very good Randy that you have understood safety importance and are involved in this one minor project for safety. You as all developers understanding insight of APM have best influence for developing safety systems.
It's sad to see cool 10k€ camera copters flying without any parachute even parachute is possible to buy from store today.
Anyway I will and hopefully many of you continue developing a chute which anyone can build if commercial version is unsuitable or too expensive. So far here is only three of us involved.
Keep it coming, very interesting! ;)
Has this spring enough force to eject the parachute from the tube? I good spring too would be the ones that are used in mattress because they aren't too stiff and have a long range of compression. Unfortunatelly i have never seen being sold in stores, just already in the mattress hhehehe
