Stan B. and I have had success converting our old hlg to dlg. It is a matter of putting the Y tail feathers with skew on, changing it to turn right and removing the finger grip and moving the washin tab from the left to the right pane. You might wonder why would we do this when the larger dlg flys so well…
Well, they are lighter, we can get them higher than we could javelin style and most importantly we can fly them with way more incidence, which make for excellent thermal ability.
I am quite sure the lager dlg gliders will out perform the smaller converted ones, but I am also sure that the smaller converted hlg will out perform the old javelin hlg….and this way absolutely everyone can fly hlg/dlg.
So get your old gliders and get them converted and you will get 100′ launches like when you were a kid!
