Although I built a short-wing (4.28m) version of my scratch-built JS3, somehow I never got around to flying it. The long version (5.14m) simply flies awesome so I’ve never seen the need to install the short outer wings. Plus the short version doesn’t quite look as good as the long-wing version.
Chocofly also offers its JS3 in the long and short outer wing version, but I only ordered the long outer wing version. A few weeks ago Dani (Chocofly) put his set of short outer wings in my hands and urged me to give them a try. We’ve had some awesome slope conditions in the past few weeks, so I did. My impressions confirmed what Dani told me: it’s a very different plane. The JS3 becomes very agile (rolls great 🙂 ) but at the same time doesn’t seem to lose much of it’s thermalling capabilities. It’s a nice addition to the JS3 that extends the range in which the glider can be used to conditions with stronger lift and wind and where the pilot wants a more agile plane.
For me, the JS3 already had the broadest range in which a glider is excellent to fly. I’ve never flown a scale glider that is so good to fly and so much fun in conditions with very little lift way up to good slope conditions. The short outer wings further extend this range upwards. Interestingly, I did notice that the JS3 accelerates faster, but I did not notice a large difference in the top flying speed (see my next post). Important to note however is that even in the short wing version it doesn’t match the Diana2, which is still my favourite plane for good to excellent lift conditions. This in partly because my JS3 is the lighter GPS edition (and thus not as robust and heavy as the Alpine or HG Editions – my Chocofly Diana2 is an early Alpine Edition), but also because of the winglets – which limit the top speed of the JS3 (the Chocofly Diana2 comes with a set of “tiplets” for when it really gets “hot”)(see my next post). That’s however no criticism of the JS3 – it’s an amazing plane for the slope, but not built as a slope racer. I very much enjoyed flying the short wing version and have ordered a set of short outer wings.
Below a few pictures of the short and long outer wing version side-by-side.
