Nice vid of a BRS save following a negative G wing failure during an airshow in Argentina. I'm not sure I'd be doing Acro in a RANS but that's just me. Glad to see he made it ok http://forums.ubi.com/images/smilies/25.gif

That is just beautiful. http://forums.ubi.com/images/smilies/25.gif http://forums.ubi.com/images/smilies/clap.gif http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif
What a life saver. This is a coincidence because I have been looking at BRS systems lately. They are expensive and since I am on a tight budget I am thinking about making my own. My concept at this time(and it is only an idea at this time) is a 3" diameter mortar tube containing a pilot chute that will be deployed by means of a chambered and altered shotgun-shell with a hammer and firing pin wire-pull device operated by the pilot and easily accessible such as a pull-ring under the seat . The pilot-chute is attached to the apex of the main chute by an 8 to 10 foot long static-line. The pilot-chute pulls out the main-chute which will be a US Army T10 reserve packed into a tube with the smaller pilot-chute tube mounted on it's side. This device is mounted behind the pilot in such a way as to not disturb the beauty or appearance of the airplane or to be noticed by an untrained eye until closer examination. I would test this device/set-up using a pickup truck traveling 20 MPH being satisfied with the testing with a total of three tests if successful. The main's risers will be connected to my seat harness. Since my plane will only be weighing about 500 pounds fueled and with me in it and is a slow-mover the devised system should be able to provide a survivable decent rate in the event of a large bird strike or some other catastrophic event that causes a structural failure. I have no intention of ever doing anything to over-stress the plane anyway, but you never know. But it's just an idea. People will criticize it for being home-made, but anything is better than nothing. The pilot in that video will gladly agree I'm sure.
Those systems are the way to go.

I don't know why anyone would ever attempt those sorts of maneuvers in anything but an Extra 300 or similar high quality aerobatic planes.

The pilot was 22. After failing to die in an air-crash he then had unprotected sex, drove home ****ed and had bacon and egg butties for breakfast, with mayonaisse. When you're twenty two the wings never come off.

At least that was my recollection.

But you're right Aimail, you'd be nuts to do that sort of thing in a flat pack kite. Go not gentle into the good night...so to speak.

Pretty sure that is the Argentinian guy in a Rans S9 ???

The Rans S9 is a purpose built aerobatic aircraft and its been around since the mid 1980's. They are very common in competition and display aerobatics, even here in Australia. I do not know the reason for the wing failure but it was likely structural fatigue in an older air frame.

Whatever the case, the Rans had smoke running so it was in a competition or display, it certainly wasn't a kid taking the local aero club Piper up for a spin.

Doesn't appear to have the same G tolerances of the Extra and the Zivko Edge 540

Anyway, like anything that's Argentinian with wings it fell out of the sky in flames. http://forums.ubi.com/images/smilies/halo.gif

-4g isn't exactly a low g-limit.
