Firstly condolences to the family and friends of the deceased
I flew Airborne Wizard, Streak 1, Streak 2, 2B Streak 3 & a SST wings
Wizard- hated it, smacked around by turbulence, speed wobbles over 45kts when tucking the bar in to lose height
Streak 1 wing- nice wing overall with inflight trim but slow (50kts)
Streak 2 nice all round wing overall with inflight trim (54kts)
Streak 2B nice wing overall with no inflight adjustable trim and set reflex (54 kts)
Streak 3 - loved it quite stable pin point your landings and reasonable speed (60-61kts hands off)
SST- overrated, claimed 70kts trim which the best I saw was 67kts but sat right wing low when in the front hole, middle hole (62kts) was much better, nice in turbulence as it was always in compression being strutted but could Dutch roll (side slip) really easy if you changed direction really quickly which was a horrible feeling as you basically felt like you flew side ways with what felt like minimal control and had to roll towards the skid to get it to basically hook up
Did it twice, first time during a S turn and second time just after it to see if it was just a 1 off
Never did it again
From what I have heard the Arrow is a SST basically with a meter off the wingspan which helped the handing some what I am told
Overall I did about 760 hrs combined with Airborne wings mostly on the 1, 3 & SST
Never had any issues other than the SST those 2 times
