Some of you may have seen the L-39 that I released a couple years ago. My main goals with that design were to make it a relatively simple build while still having it resemble the L-39, as well as giving the builder the ability to fly it with a 50mm EDF, or an equivalent to the FT F pack. After flying it for a year or so I started to notice how boxy everything was, and I found lots of little spots where I could make the design a little easier to build and more importantly, look quite a lot better.
For version two, my goal was simply to retain or improve the awesome flight characteristics of the original design, while getting the model to look more like the full size L-39. This is the end result!

The biggest changes I've made are adding many more facets, and changing up the geometry of the intakes as well as other curves. Aside from a slightly bigger horizontal stabilizer the plane has the same wing and vertical stabilizer located in the same spot on the airframe so the flight characteristics of the original model are carried over into version two. The EDF power system has not changed so if you've built V1 as an EDF you can build version two, sadly the option to build the jet with a FT F pack equivalent is no longer available, although retrofitting one wouldn't be too difficult.
Top speed is great and slows down very well for landing. I was able to clock V1 doing 64 mph at Flite Fest and V2 definitely feels a tad faster, so I'll say it is the realm of around the 70 mph.
The L-39 tracks like an arrow and the controls are very smooth giving you the ability to fly like a pattern ship, but it can become "snappy" and abrupt when you really start banging the sticks around.
If your plane stalls it will likely drop a wing but it is nowhere near entering a spin, all you have to do is level the wings and then power out.
Since the plane lacks a rudder the aerobatic ability is limited to the basics such as, Loops, Rolls, Inverted, Split S's etc.
I like launching this plane by holding it right in front of the wing and giving it a really strong toss, you really need to give this bird a solid toss or else it won't have enough airspeed to sustain flight.
Landing this model is quite simple all you need to do is bleed almost all your airspeed and get it close enough to good 'ol terra firma to put ground effect to work, then right before to hid land, flare the plane and you'll "ride" a cushion of air to the ground.
I'd want to wait until I've flown at least one unforgiving plane that flies quite fast and taught you how to avoid stalling.
