Dear reader,

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 :)

This blog will still be updated as well our Facebook pages www.facebook.com/skycat.pro and Twitter at https://twitter.com/skycatpro

Fly safe - Let's keep our copters flying!

Christian, 

No reason here to feel disrespected :)

All emergency recovery systems on market for Inspire 1 which I've seen are controlled similarly: PPM or PWM signal to recovery system and parachute is released. If there are partial solutions available it doesn't mean it is more simple. It just means that you need to figure it out how to use it by yourself.

If someone has a radio or automatic eject module which is able to control RC servo, it can control all of these today known recovery systems.

Our reseller has just bundled package with all needed gears including independent radio which is easy and simple solution today. There are people who need plug&play recovery system now. When another control solution is introduced, could current RC transmitter be replaced with that new one. With Skycat you can still use use original transmitter if you want and also another new one, i.e dual radios.

I know - it is not possible to get a servo signal out of the flight controller on the Inspire 1.

That is in fact what I am looking for. A simpel 2,4 GHz TX/RX system with one channel that can control a servo. If a product like the transmitter in the french video exist it could also be a product for your reseller and still be a plug&play product.

Hello Christian Wiggers!

I don't know if it can help you but I think there is something to do with this system with a mini Arduino and an accelerometer. With time to configure it, I think it could avoid the necessity of having another remote control.

Or maybe with the Mayday module from North UAV?? A little pricey but I think it could do the job.

I have seen the Mayday system, and i think it look promising. But for now I would like at manuel system, were I control when it shall work. I have a idea about mount a SPS Safetypowerswitch so when the parachute deploys the power cut off.

It is very important that the system is simple and works every time because the Danish transport and Construction agency is going to test this system and hopefully approve it in the same way as with redundancy is approved on the S900 and S1000.

Mayday looks promising attempt for automatic eject. We are one of the Kickstarter backers and are eagerly waiting unit for test.

On another forum, someone told about the camremote module to trigger his parachute

Pixhawk automatic parachute recovery worked!

Setup was our test quad copter with Pixhawk and latest beta 3.3 firmware. We used two Triggers: one for Pixhawk manual/automatic eject and one Trigger connected directly to RC receiver for backup. In case Pixhawk had failed we could have ejected normally using pilot radio. It is good to have two or even three triggers for different sources and radios for redundancy. Once ground station is able to eject we'll do Trigger for it also. 

We tried two different kind of recoveries and two of each:

  1. Manual eject request. CH7 was set for eject request and it worked as should.
  2. Automatic eject. One motor was powered via relay (Skycat relay trigger) and from altitude approx 50 meters we shut one motor down by cutting it's main power (+ cable). Copter tilted immediately and started fast spinning one motor arm pointing to ground. It took perhaps 10 - 20 meters of fall and then parachute was ejected. Both attempts were visually similar.

Video is on youtube today.

It was only four tests we made but based on results I would activate automatic eject for casual flights. As video shows everything happens very very quickly and if pilot freezes on critical moment, then automatic eject is at it's best.  For over the crowd and other risk flights I won't use it yet and in all cases would recommend to use two eject sources: One for Pixhawk and one for pilot. If autopilot freezes, you still can take copter down using pilot radio.

ah, excellent!  Bring on the video!

You'll see it first thing in the morning in Japan!

We combine quickly two camera video today and sometime later make more comprehensive with all four cameras we had. This time we have for sure enough angles to view.

Here is the video of an emergency situation which Pixhawk controlled all the way automatically and ejected parachute. All we did was motor failure using RC controlled relay to cut power of the motor:

Awesome Henri!  I'll be sharing this!

Thanks Gene!
