My "discontinued item" sailplane arrived today and to my surprise it wasn't a Hacker Sting but rather a Norvel GlassAir 400 ARF Motor Glider.
The ship is almost identicle to the sting in specifications but now I can buy spare parts for it on-line! It can be configured for either a .049-.061 glow or a Speed 400 4:1 Speed Gear with an 11x8 folding prop.
Maybe...just maybe, Hobby Lobby is picking up the GlasAir line in their new Catalog 37. When they ran out of Stings, they substituted it with the Norvel model.
