Had my first-ever quad-line experience today. A 60-minute outing with my brand new 1.5 SLE.
It went surprisingly well. Quite a few crashes, but I was expecting that and they were gentle-ish, non-fatal ones.
It's easier to launch (re-launch) a Rev than a delta.
There were a few problems though.
The LE end caps kept coming off.
On 3 or 4 occasions the lines suddenly (and for no reason that I could see) went VERY slack and the kite fluttered down, LE first and very gently, to the ground. Usually from quite high up, and slightly off the middle of the window.
It's very hard to set aside the automatic, dual-line reactions. Must see about buying a pair of handcuffs ...
Oh, and when I got back home and re-ran the instructional DVD, I discovered I'd fitted the vertical shafts on the wrong side of the sail (ie, on the bridle side). It still worked though. Sort of.
Shall try again tomorrow!
(PS - Is it necessary to stretch/equalise a set of newly-bought Laser Pro Gold lines?)
