Although it might not be ideal for a 1st time build, this model could make a great EDF trainer (if it came with some decent landing gear). That had to be my biggest dislike on the JAS-39. The landing gear is what I'd consider a joke. (a bad one at that) Included in the kit is a full armament package for those that want a scale display, but it flies slow enough without the added drag.
I bought this one as soon as I spotted it and read that it was "90 mm fan ready". Unfortunately, what Sapac considers 90 mm ready is considerably different from my own idea. Check my Projects page for an in depth on the build and modifications I made to accommodate the Wemo midi and Hacker B50-9XL that is powering mine. There you can also find a link back to a build/discussion thread on RC Groups that could prove useful as well.
Unlike the Sapac Eurofighter that comes with the control surfaces pre-hinged, you have to cut the surfaces loose on this kit and cut hinge slots yourself. I elected to use the thin CA type hinges installed with Yardbird RC's ultimate RC foam glue (URCFG) to make life a little easier. I also used Blenderm tape to seal all hinge gaps. Other than that, 5 or 30 minute epoxy was used for the rest of the construction.
Radio gear consists of 4 Hitec HS-82mg servos controlled via a Spektrum 6100 receiver with a Castle 10 amp BEC supplying receiver power. The ESC in mine is a Turnigy plush 80 amp and a Zippy-R 4800 ma 5s lipo finishes out the power scheme.
At 6 pounds, my JAS-39 is about 2-1/2 pounds heavier than advertised for a stock 70 mm version due to the modifications that included a fiberglass inlet duct, glasswork on the bottoms of the wings, and total repaint after assembly. The big battery helped contribute to the weight too. In spite of the extra pounds, it's still a bit of a floater and handles well at slow speeds. If you manage to stall it, it falls straight forward with no snap or roll tendencies. My other complaint would be that it's not very fast either. I'm guessing that top speed on mine is somewhere in the 65 to 70 mph category. I had the same motor, fan, ESC setup in a Fly Fly Mirage that would do close to 90 at about the same weight. Not sure of quite what the difference is as both are similar in size, too.
It does look good in the air though. With it's good handling it makes for a stress free (almost boring) flight until time to land. Then you need to be "on the money" and grease it, or you can be sure the flimsy gear will collapse. My 1st flight attempt didn't make it off the ground due to insufficient angle of attack with the stock setup. It ran off the runway into the grass (at speed) and folded all 3 of them up against the fuselage.
