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!

Hi Henri,

Ok, I'll have a look at the logs and see if I can figure out why it took so long to eject.

Hi Randy,

Great! Check also if Pixhawk ejected at all or was mine manual radio request first. It was Taranis, X8R with SBUS in connected to channel 7 if I remember correctly.

We try to make some setup which allows to determine delays more accurately. High speed video on standing copter is one option. Most difficult is to rule radio delay out. Accurate analyze would need oscilloscope where one trigger is set to receiver channel signal pin monitoring PWM High state (to Pixhawk). It tells accurately when command is set.
And another trigger to output. Delay in between these is Pixhawk delay.

This just takes some time to setup all properly.

Hi Henri, Are you testing the new 84" chute?  Look like it ;)

Now it is something huge in air! 

To put this in to correct perspective; copter on image is one meter from motor to motor.

Hi Henri, That is the IFC-192-S we shipped you, it has 18 gores!  That is an awesome photo.  I don't see a lot of photos on this chute.  So the chute is 16' across (almost 4 meters).  The chute is rated up to a 92Kg load.

Can you tell me about the copter?

Gene,

This is your largest parachute IFC-192-S! You'll get this photo and lot more once artists has tuned them, this was just quick screenshot.

Copter is our heavy lifter X8. This time it had easy flight weight 9 kg which it can lift with four motors. With 8 motors it should be capable to lift 13 - 17 kg to eject altitude. Flight controller is The Pixhawk.

Pixhawk 1 automatic eject worked on "real" case!

Auto mission start from table was slightly too careful and copter flipped off the table after some centimeters. Ground effect changes perhaps too quickly on this case and aggressive take off is required.

Anyway, parachute was ejected! Minimum eject altitude is set to 0 meters and therefore it was ejected towards the ground..
