Last w/e I was demo jumping the new Rage 97. I was loading this canopy at 1.55 (I have over 900 jumps), and had talked to my canopy coach before test jumping it, regarding the probable characteuristics. He expressed some doubts as to whether the new breed of canopy with the formed nose to keep the wing more rigid (and improve the aerodymamic qualities) was actually as effective as claimed. His belief was that they could react unfavourably to turbulence, the wakes of other canopies etc. I made two uneventful jumps on the Rage and then went to make a third. I found myself a little crowded in the landing pattern as I was tending to catch the canopy ahead of me. I was unable to turn inside this canopy because I was wary of crossing a line of tall trees which produce a fair amount of roll so I flew a little wide and only turned in after the other canopy after it was quite some distance ahead of me- I would estimate at least 100ft if not more. At the point where my canopy intersected the wake of the other the right hand side suddenly and dramaticly collapsed and it fell into a sharp downwards and backwards spiral, throwing in line twists as it went. At this point I was at approximately 300ft AGL. I fought to clear the twist and succeeded but was then left with a canopy that still had most of the cells on the right collapsed and was now spiralling forwards to the right at high speed. I was only able to re-inflate the canopy with some difficulty by pulling on the right control toggle about 3-4 times in succession and managed to get a good canopy above my head by 50ft AGL to come in for an off landing in a ploughed field next to the landing area. I feel that a canopy that reacts in this manner to what must have been a fairly mimimal amount of wake must present safety issues as regards the design characteuristics. I would be interested to hear if anyone else has experienced this type of problem with the Rage?
